The lock is TuyaMCU based and uses WBR3 Wifi/BLE module which is based on RTL8720CF; TUYA IOT SDK V:2.3.1 rtl8720cf_common_lock_ty:1.1.16 pid:umca8uiv2203ua3k firmwarekey:key5943jddfsyeu3 v1:1.1.16 v2:1.3.9 Tuya-CloudCutter wont work as its not entering AP mode. Flashed OpenBeken FW, but cant set properdpIDs Thanks. I’m running a Tuya-based smart lock that currently relies on Tuya’s cloud, and I want it to function entirely inside my LAN. Lock, unlock, status, battery level—everything has to stay, but without any call home. What I need is solid API integration work. Whether you reverse-engineer the existing Tuya local protocol, pull the device keys, or wrap native commands in MQTT/HTTP, the outcome should be a clean local API I can hit from Home Assistant or a simple...

I already have a reference Chrome extension that automates web-scraping tasks, and I need an exact replica—interface, behaviour, and results must match 100 %. The extension grabs structured data from targeted pages, so every selector, background script, and content script has to mirror the original. I will provide access to the live extension, sample URLs, and the specific data points it extracts; your job is to recreate the same flow under a fresh codebase that is Manifest V3 compliant and free of third-party licensing issues. Because I need this ASAP, please be prepared to start right away, show rapid progress, and hand over a fully functional CRX plus readable source code. I will verify that: • the scraped output is identical to the reference for the sample pages, • ...

I need to start accepting payments on my ecommerce site through our CRM, Vrio. I’m open to two approaches: you can either build a small-scale custom gateway for us or hook us up with an existing processor or merchant account—whichever proves faster and more cost-effective. The critical point is that the chosen solution must plug into Vrio’s API cleanly and stay fully compliant with PCI-DSS. Required payment methods are straightforward: credit and debit cards plus direct bank transfers. If the platform you recommend also happens to support digital wallets, great, but it is not mandatory for launch. Core features we can’t launch without: • Recurring billing that talks to Vrio’s subscription module without manual workarounds. • Multi-currency supp...

Install and setup self hosted Joplin Server with Nginx and Let's Encrypt SSL Certificate on Ubuntu or AlmaLinux VPS And Document the Full Setup Process including the commands to build out the server and configuration files.

I’m building a high-speed communication interface on an STM32-based board and need production-ready firmware written in C/C++. The microcontroller is an ARM Cortex-M series device, and the single most important goal is to move packets through the interface as quickly and reliably as possible—latency can be modest as long as overall data throughput remains very high. You will design and code the full communication stack, configure the peripheral clocks, DMA, interrupts, and buffering strategy, then expose a clean API that my application layer can call from RTOS or bare-metal. Low-level register work is fine, but you’re equally welcome to leverage STM32 HAL/LL or CubeMX if that accelerates development; the final code must compile under STM32CubeIDE or GCC-based Makefiles...

I need an AI-driven auto-responder that plugs straight into my email workflow and replies in clear, natural-sounding English using a library of predefined templates I will supply. Here is the core of what I’m after: • When a new message lands in the inbox, the system should detect the intent, choose the correct template, merge any dynamic fields (name, order number, date, etc.) and send the reply automatically—no manual review unless I flag an exception. • I’m working only with email right now, but I’d like the code organized so additional channels such as WhatsApp or Slack could be added later without rewriting the logic. • Templates will live in a file or lightweight database that I can edit myself; the responder should reload them without ...

We are building a fuel tanker trailer monitoring system (pilot project) for petrol-PMS/diesel (AGO) distribution clients in our region. We have a detailed technical blueprint and now need: 1. Organizations/suppliers who can provide industry‑rated, ATEX‑compliant hardware (fuel level probes, smart GPS locks, telematics gateways, etc.) at prototype‑friendly pricing, ideally with OEM/white‑label options. 2. Embedded/firmware engineers and backend/API developers to integrate this hardware with our web/mobile platform via Modbus RS485, MQTT, and REST APIs. Note: This is a pilot project phase with ability to scale the concept to a wider client base after the tests. What We Already Have Complete system architecture and hardware list but need to know if we can get manufacturers with industry rat...

Hello, I’m looking for a software/web developer who could help me turn an idea into a simple, user-friendly platform. The concept is similar in some ways to NFC digital business cards. With these, a physical NFC card is linked to a unique user profile, which can be opened simply by tapping the card against a smartphone. My idea would use the same principle, but for storing and accessing documents and images. Each customer would receive a physical NFC card, also containing a QR code, which I am able to manufacture and programme myself. The card would be linked to that customer’s unique account. When the customer taps the NFC card against their phone, or scans the QR code, they would be taken directly to their own simple user area. From there, they could: - Create folders -...

I want a single, fully-automated application that lets customers in multiple cities book our on-site services—painting, home cleaning, plumbing, and electrician work—while also letting them purchase industrial safety goods that ship from our main warehouse. The build must ship on iOS, Android, and the Web and recognise three clear user roles: Admin, Customer, and Gig Worker. Customers will browse services or products, lock in a slot or place an order, pay online, and receive an invoice generated automatically in Zoho Books. As soon as a job is confirmed it should flow to the nearest available Gig Worker, who will see it in real time, accept or reject, navigate to the address, update job stages, add photos, and close the task. Throughout the process the system must provide: ...

I need a production-ready eKYC solution whose sole purpose, for now, is identity verification through facial recognition. The first milestone is a browser-based flow: the user grants camera access, the system performs liveness checks, matches the live capture with a reference image and instantly returns a pass/fail result while logging the outcome in an encrypted store. Parallel to this, I want the exact same verification logic exposed to my mobile apps through an SDK or well-documented REST / GraphQL API, so React Native, Flutter or native wrappers can call it with minimal overhead. Performance, security and privacy sit at the heart of the project—sub-two-second response on 4G, GDPR-compliant data retention, HTTPS everywhere, and role-based access controls. While we are starting wi...

Please share the following: 1....

I’m building an application whose core value is actionable forecasts generated by AI-driven predictive analytics. The idea is to feed historical data into a well-designed pipeline, surface trends, and return clear recommendations or probabilities to end-users inside a clean interface. I have not locked the project into a single sector yet, so whether the data turns out to be time-series sensor readings, customer behaviour logs, or financial records we can choose the most suitable modelling approach together. Here’s how I picture the flow: first, you and I refine the problem statement and decide what questions the model must answer. Next comes data ingestion and cleaning, followed by feature engineering and model selection—think scikit-learn, XGBoost, TensorFlow, or which...

I have a source Telegram channel with well over a thousand people. I am only a regular member there, yet I’d like to pull out just the recently active accounts and move them into a second channel that I own and administer. Here is what I need from you: • A working method (Python / Telethon, TDLib, or another reliable approach) to scrape the member list, filter for users who have been active recently, and then add them to my destination channel automatically. • The solution must cope with Telegram’s rate limits and any relevant policies, so batching and delay logic are essential. • A short read-me that lets me rerun the process whenever I want, plus any API keys or configuration tips required. • Proof of concept: after we test, at least a small samp...

I run a public Telegram channel with 30 000+ members but only a fraction appear truly active. I need a specialist who can dive into the Telegram API / MTProto from the vantage point of a regular member account and tell me, with evidence, exactly what member-level data is retrievable. The priority is clear: I want to know whether user IDs and usernames can be enumerated, how many can be reached, and under which technical or policy constraints. While you are exploring, please note any practical way to spot genuinely engaged users, describe the rate limits you hit, and flag the differences I would face if I ever upgraded the account’s role. Deliverables • A concise proof-of-concept script or notebook that demonstrates the maximum data you were able to pull as a standard member, i...

I need a developer who can take this accounting workflow out of spreadsheets and into the cloud. The core of the job is to deliver a web-based platform hosted on Firebase, with data stored and transmitted securely. What the application must do • Let me spin up unlimited “companies” so each business keeps its records completely separate. • Provide simple Email-and-Password authentication for every user role. (If you think we should layer OAuth or 2FA later, keep the codebase ready for it.) • Offer a clean UI where I can create customers, assign them to groups, and then post two entry types—Payment or Journal Voucher. • For each entry I’ll input debit, credit and a narration; the system automatically stamps the exact date-time and shows ...

My WhatsApp Business account is already fully verified; the missing piece is a live Meta app that lets me run large-scale marketing broadcasts through the official Cloud API. I need you to step in, create the app in Meta’s developer portal, complete all required configurations (system user, phone number, webhooks, message templates), guide it through App Review, and hand it over ready for production traffic. Once the app is live I want to be able to send segmented promos, coupons, and new-product announcements directly from my backend, so please wire up a lightweight example endpoint or script (Node.js or Python is fine) that shows how to trigger a broadcast to an uploaded contact list and how to pull delivery analytics. To keep the hand-off smooth, make sure the final setup covers...

I want to bring to life a cloud-based platform that unifies three core functions a modern accommodation business needs: a real-time channel manager, a full property-management system, and an on-site POS, all knitted together through a third-party API. Scope and objectives The system must work smoothly for every accommodation style—hotels, vacation rentals, hostels and any hybrid in between—so configurability is crucial. Inventory, rates and reservations have to flow automatically between the PMS and the external API, keeping OTA listings perfectly in sync while preventing over-bookings. At property level, staff should be able to handle the entire guest journey from booking to check-out and settle ancillary charges at the POS without touching a second screen. Key PMS modules...

I’m building a full-fledged marketplace where multiple sellers can list and ship physical products. I need the entire ecosystem put together—from a responsive web storefront to native mobile apps for both iOS and Android—so customers can shop seamlessly on any device while vendors manage their own inventory, orders and payouts in real time. Key requirements • Multi-vendor architecture: separate vendor dashboards, commission setup, product approvals, dispute management and detailed sales analytics in the admin panel. • Cross-platform experience: one code-base or tightly aligned builds that deliver the same feature set on the web, iOS and Android without sacrificing speed or UI polish. • Secure checkout: integrate Razorpay as the primary gateway and ...

I run a pulse-milling and trading operation that has outgrown our single-user Tally setup. I now need a multi-user, multi-location ERP that reflects the way we actually work and eliminates the bottlenecks we face each day. Core scope I want one unified system that covers every step from raw-grain intake through finished-product sales, while still letting my accountants post to Tally for statutory reporting. Speed, reliability and an interface my staff can pick up quickly are all critical. Key features required • Inventory management that follows stock from silo to bag, supports multiple godowns and shows real-time levels across branches. • Sales tracking that links orders, dispatch and invoices, with the option to apply customer-specific or time-based discounts automati...

I’m building a full-stack web application in Python with Flask at its core and I want it to feel as polished as any modern SaaS product. The visual layer needs to be clean and responsive, while under the hood the code should be clear, modular, and thoroughly tested. Core functionality • Secure user authentication that covers sign-up, login, and password reset flows. • An admin dashboard with CRUD control over key records in a relational database (PostgreSQL or similar, using SQLAlchemy). • Real-time API integrations that pull external data at scheduled intervals. • Interactive dashboards that present that data through charts and graphs; think Plotly, , or any library that handles live updates smoothly. My expectations I’ll rely on you to design i...

I need a complete web-based freelance job network built from the ground up. The core idea is similar to the big freelance marketplaces: clients post projects, freelancers create profiles, and both sides can connect and transact in a safe, intuitive environment.

I’m looking for a versatile engineer who can jump in right away and keep our product moving forward. The work is continuous and touches every layer of the stack: sharpening existing AI logic, extending backend services that feed it, and refreshing front-end elements so users immediately feel the impact of each release. What you’ll actually do is simple to state but vital to execute: pick up the next feature, ship it cleanly, document just enough for the team, and get ready for the one after that. Some tasks may revolve around tweaking or retraining models, others around streamlining API endpoints, and still others around refining the user interface so new capabilities surface beautifully. I need fast turnaround, solid testing, and proactive communication because these updates ...

I’m building a mobile-first fintech app for cab drivers and delivery riders that gives them access to a credit-based wallet. In the first release the wallet must let users draw and spend fuel credits only, yet the codebase has to be flexible enough for us to turn on insurance and utility credits with minimal rework. What I need is the complete product journey: an iOS and Android app for the workers, a slim merchant view so fuel stations can accept payment, and a secure backend that approves credit, settles transactions in real time, and tracks repayments. KYC, instant balance updates, push notifications, and straightforward spending analytics all belong in the core scope. Use whatever modern stack you are fastest with, provided it integrates cleanly with common payment rails and ide...

I need a complete software-development partner to turn my web-application idea into a running product. The core objective is to design, build, test, and deploy a modern, browser-based application that is fast, secure, and easy to extend. Here is what I have in mind: • End-to-end build: information architecture, UI/UX wireframes, front-end coding, back-end APIs, database schema, and cloud deployment. • Clean, well-commented source code stored in a Git repository I can access at any time. • Technical stack recommendations—feel free to suggest React, Vue, Angular, Node.js, Django, Laravel, or whatever you believe best meets the brief; I’m open to your expertise. • Responsive design so the app works smoothly on desktop, tablet, and mobile browsers. &bu...

I’m putting together a restaurant POS modeled closely on the Petpooja experience, and I need the backbone of the system built right away. Your task is to create clean, well-documented PHP APIs that my mobile and web teams can plug into immediately. Scope of the APIs • Core focus: real-time inventory management—stock levels, item variations, automatic deductions after each sale, low-stock alerts, and simple purchase-order generation. • Seamless sales and transaction hooks so that, when I’m ready, we can extend the same codebase to cover billing, reporting, and customer data without rewriting everything. • Secure authentication, role-based access, and clear JSON responses are mandatory so integration stays painless. • MySQL (or MariaDB) is prefe...

I need a full-cycle build of a School Management System delivered as a dedicated mobile app for both iOS and Android. The solution must include a solid back-end, restful APIs, and a well-structured database so that the Admin, Teacher, and Student roles each see only what they should. A classic username-and-password flow is enough for the first release, but it must be implemented securely with proper session handling and encryption in place. Core modules I expect from day one are fee tracking, attendance, timetable, examination results, push notifications, and printable reports. Everything should be responsive to different screen sizes, optimised for low-bandwidth scenarios, and ready for future additions such as two-factor login or parent access without major refactoring. Deliverables ...

My C#-based desktop trading front end now needs a direct, real-time link to Sterling Trader Pro. The goal is full API integration that goes beyond a simple data feed: live quotes and depth, every order type Sterling supports, position & risk updates, plus a back-testing harness on the same codebase so strategies can run historically before they trade live. The current application is stable and well-structured; what is missing is the Sterling layer—authentication, session management, event handling, and the conversion of our existing order objects to Sterling’s message format. All work must remain in C# and respect Sterling’s API guidelines. Deliverables • Connection module that authenticates and maintains a persistent Sterling session • Real-time market ...

I am looking for an experienced developer/team to build an MVP civic issue reporting platform for a beta launch in Kanyakumari District, Tamil Nadu, India. The long-term vision is to expand the platform across Tamil Nadu and eventually Pan-India, so the backend and database architecture should be scalable. The platform will allow citizens to report genuine public/civic issues such as potholes, garbage, drainage, water problems, streetlights and other local infrastructure issues. This will initially operate as an independent citizen platform, not an official government application. Core Citizen Features The first version should include: * Simple mobile-friendly interface * Tamil + English * Citizen registration/login * Report an issue * Upload photo/video * Automatic GPS/location capt...

I manage several property listings and, every day, messages arrive in Spanish across Text messages, WhatsApp, Facebook Messenger and Google Voice. I need a single AI-driven solution that can automatically pull each incoming message, translate it to English, understand whether the sender is asking about an available property, a booking detail, or a maintenance issue, and then craft a reply that feels helpful and human. For the reply style, I want a mix of both preset templates (e.g., directions to the property, check-in times, basic troubleshooting) and dynamic, context-aware wording that adjusts to the exact question or concern. The system should log all conversations, flag anything it cannot classify confidently, and let me jump in manually when needed. Please build or integrate with th...

My AI-generated CRM is 90 % there, but a mix of functional, interface, and performance glitches keep the core experience from feeling complete. Automations stall, nurture sequences stop midway, and the cross-selling module never fires. I need a developer who can: • Trace and squash the current functional, UI, and speed issues across the entire codebase. • Finish and hard-test the automation engine so every trigger, timer, and conditional fires reliably. • Build out the full follow-up nurture flow—email/SMS templates are ready, they just need proper sequencing and fail-safe logic. • Activate the cross-selling feature set so related-product offers surface at the right moments. Acceptance will be a fully working CRM where: 1. All existing bugs are clo...

I have an existing WhatsApp group whose entire membership I need copied into a fresh group. The task is purely about replicating the member list—no chat history or custom settings have to come across—so the solution can stay lean and compliant with WhatsApp limits. The current head-count is well over 100, therefore I’m looking for an automated method (API integration, approved third-party tool, or a lightweight script) that can: • Pull every existing member ID from the source group • Add them seamlessly to the new group without triggering spam flags • Provide a simple way for me to repeat the process in the future if the roster changes Please build in any required rate-limiting or invitation workflows so we respect WhatsApp’s policies. On deliv...

I need a skilled web developer who can take a concept for a new website, app, or full-scale platform and turn it into a production-ready product. The scope is broad: it may be a business or corporate site, an e-commerce storefront, a booking system, or an entirely custom web application, but the common thread is that the finished build must be fast, responsive, scalable, and easy to maintain. Here is what I’m looking for in practical terms: • End-to-end development — planning, UI/UX, front-end and back-end code, testing, deployment, and post-launch support. • Modern tech stack familiarity. If you regularly work with React, Vue, Angular, Node.js, Django, Laravel, Rails, PostgreSQL/MySQL, MongoDB, AWS, Docker, REST or GraphQL APIs, you’ll feel at home here. ...

I am looking for an experienced full-stack developer to build a simple, modern and mobile-friendly classified marketplace. The platform will allow individuals and businesses to list new or preloved items for sale. Buyers can purchase items in three ways: 1. Fixed Cash Price – Seller sets a price and buyer purchases. 2. Make an Offer – Buyer submits an offer; seller can accept, reject or counter. 3. Auction/Bidding – Seller sets a starting price and buyers compete by placing bids. Key features: * Simple user registration and profiles * Verified user profiles with verification badges * Post listings with photos, descriptions, price and location * Categories and search * Filters by price, location, condition and selling method * Buy Now, Make Offer and Bidding functional...

I already have RPR’s Broker AVM script and token working when I hard-code a property address, but I need a small JavaScript tweak so site visitors can type any address and instantly see the valuation. Here’s the flow I’m after: • An address field sits right inside the existing widget code—no new layout blocks; it should feel native to the page that already hosts my contact forms, listings, and search tools. • On submit, the script captures the typed address, swaps it into the widget’s Query parameter, and calls the RPR service. • The returned valuation opens in a clean, responsive pop-up modal (desktop and mobile) and stays on the same page. • Everything must run inside Sierra Interactive’s Shared Widget / JavaScript environme...

I am looking for an experienced developer or development team to help build a vehicle transport load board and transportation marketplace, starting with the Canadian car-hauling industry. The concept, business model, workflow, core features and initial visual prototype are already defined, and we are now ready to move into MVP development. Unlike traditional bidding platforms, our model is based on fixed-price loads: a dealer posts a vehicle or load at a set price, a carrier can accept it instantly, and the assigned driver manages pickup, VIN verification, vehicle inspection, photos, signatures, GPS tracking, delivery inspection and eBOL through the platform. We want to build iOS, Android and web/admin together on one shared backend, with one mobile app that provides different interfaces f...

I need a web-based inventory system that lets me see, in real time, what I have on hand, what has been sold, and exactly how each sale affects my bottom line. Every stock-keeping unit may be purchased or produced in lots, so the system must allow me to group items by lot, trace their movement, and reconcile quantities automatically. As items leave the warehouse, I want automatic profit-and-loss calculations that factor in cost per lot, selling price, fees, and any manual adjustments I make. Day-to-day, my staff will also use this platform as a lightweight task manager: assigning picking, packing, restocking, and counting duties with deadlines and status updates tied back to the relevant stock items. A clear dashboard that shows outstanding tasks alongside key inventory and financial metri...

We run a workflow-automation SaaS that lets customers build event-driven processes, route approvals, and call external services. The stack is Java 17, Spring Boot, PostgreSQL, Celery, Redis, Docker and AWS, all delivered in a fully multi-tenant environment. The immediate goal is to harden security and drive horizontal scalability without slowing feature delivery. That means: • Strengthening authentication, authorization and tenant-isolation layers • Stress-testing and tuning PostgreSQL schemas, indexes and queries for millions of tenant rows • Refining REST/JSON APIs so third-party services can plug in cleanly, with versioning and clear contracts • Profiling Spring Boot services, Celery workers and Redis caching to remove bottlenecks, then containerising improve...
