I need my existing app wired up to an existing external REST API so it can securely fetch data, submit updates, handle authentication, and allow users to upload files. Most endpoints accept/return JSON, and uploads are sent as multipart/form-data — your code must handle both cleanly and reliably. Deliverables: A small, reusable, well-typed API client layer (e.g., /lib/api or similar) using fetch or Axios Authentication integration (bearer tokens / OAuth details provided). Requests should be signed correctly and handled consistently across the app Example usage: at least one working flow for: data retrieval data submission login/session handling file upload (multipart/form-data) Robust error handling (including loading + failure states) and a short README explaining patterns...

Android App UI Replica (Jetpack Compose) General Information I have an existing Android application only as an APK file. There is no Android Studio source code — only a decoded version via apktool (res, drawable, xml, png, smali). The app is written using Jetpack Compose, so this task is NOT reverse engineering. The goal is to recreate the UI visually 1:1. I will provide: - APK file - decoded resources - screenshots of all screens The final result must be a clean new Android Studio project. Application Concept Type: Personal account / dashboard application 1. Splash Screen - Shows a welcome image - Duration: ~2-3 second - Automatically navigates to PIN screen 2. PIN Code Screen - 4 circles at the top - Numeric keypad (0–9) - Tap animation similar to original - Hardcode...

The project involves the creation of a DB diagram to host the invoice data and a log table with the complete result of the processing/outcome of each individual invoice.
I need a Telegram-based AI assistant that can act as a true subject-matter expert. The core idea is simple: we will feed it a large, well-structured document set from whichever industry offers the richest material, then let the bot do the heavy lifting. While the sector itself can be decided once I see which corpus is most complete, the bot must speak fluently about Artificial Intelligence concepts in particular, as that will be a recurring theme in user queries. Once deployed the assistant should: • read and index every document I supply (PDFs, Word files, web links, internal wikis) • answer ad-hoc questions instantly, citing sources • provide actionable recommendations where appropriate • deliver concise summaries of lengthy texts on request I expect a smo...
I want to commission a full-featured Android application dedicated to organising eSport scrimmages and small-scale tournaments. My budget for the entire build is approximately US $1,000, which I will release in clearly defined milestones (prototype, beta, final release, and demo video). Core scope The app has to let players create and manage teams, schedule matches effortlessly, and keep ongoing statistics so organisers can review past performances. Because most users will expect a quick sign-up flow, social-media login options (Google, Facebook, Twitter) need to be baked in from the start. I also need a lightweight in-app payment gateway so teams can pay entry fees or unlock premium brackets without leaving the platform. Deliverables • Production-ready Android APK and source co...
I'm looking for an experienced programmer to create a custom plugin/mod for the upcoming Spellbound SMP. All details for the plugin can be found in the document below. On this SMP, I'd like the first hostile mob a player kills to grant that player a buff, based on the mob in question. This assigned buff can only be reversed via use of a Reset Star, the recipe for which is also found in my doc. Our budget to start is $100, although a larger price is negotiable. I've wanted to do this for a very long time, and it'd mean a lot to me and my community if you can help me with it. It should go without saying that you'll be fully credited for your work in the descriptions of all my videos, and if you'd like to join the SMP once this is done, you can. I'd prefe...
I’ve reached the final polishing phase of my mobile game and now need a fresh set of eyes to put every Android build through its paces. Your task is to install each release on real devices (emulators alone will not be enough), explore every menu, level, and feature, and then document anything that feels broken, confusing, unbalanced, or sluggish. Please capture issues in clear English, attach screenshots or screen-recordings where visuals help, and note the device model, OS version, and steps to reproduce so my dev team can act on them quickly. Performance metrics such as load times, frame-rate drops, battery drain, and unexpected data usage are especially valuable. I’ll share the current APK, change-log, and a brief list of focus areas as soon as we start. We’ll wo...
The FIGMA for my credit-card-offers app is complete; now I need the server-side engine that will make the screens come alive. The scope is an MVP-ready backend built from scratch, including both the API layer and a brand-new database. The will work in sync with a browser extension being developed separately. I haven’t committed to a tech stack yet, so feel free to suggest Node.js, Python, Java, or another modern choice you’re comfortable maintaining. Whichever stack you choose, I expect. Need to develop both Android and iOS.
I need a clean, modern Android application that lets diners browse our menu with attractive photos, clear prices, and smooth yet simple animations. Customers will be able to place an order straight from the app; instead of a payment gateway the order screen will simply present the restaurant’s phone number so they can call or message us to confirm. Only dish names and prices should appear—no long ingredient lists—and absolutely no purchase-history screen is to be stored or shown. An admin area must exist, hidden behind a single secret code. Once inside, the authorised person can add, remove, or swap dish names, photos, and prices. No other user should even see that this option exists. Deliverables • Full Android Studio project and signed APK • Admin code ...
I need structured, beginner-friendly coaching that will take me from “hello world” to employable in Natural Language Processing. My goal is to understand core NLP concepts, build a small portfolio of projects, and feel confident discussing them in interviews. I already code a little in Python but have no formal NLP background. I’d like to cover the foundations—tokenisation, embeddings, transformers—then progress to hands-on mini-projects using libraries such as spaCy, Hugging Face, TensorFlow or PyTorch. Guidance on best practices for data preprocessing, model selection, evaluation and error analysis is essential, along with tips on how to present this work in a résumé or GitHub repo. Deliverables I have in mind: • A personalised learning ...

We need an Android developer to add iPhone-style panorama to the Open Camera app (open source: ). Goal: Implement panorama in Open Camera so it works like iPhone: guided on-screen motion, smooth horizontal panning, and one stitched panorama image. • Works seamlessly on both the front and back cameras. • Guides the user with the same arrow-line UI Apple uses, keeping motion smooth and level. • Captures a continuous series of frames, stitches them on-device, and outputs one high-quality image without pushing memory limits. You’ll work only against the official Open Camera codebase (or a clean fork you create). I’ll take your branch and merge it into our own app later.
I need help changing the visible name of an Android application that is already installed (or will be installed shortly). I will supply the current package and the existing project files; the new label itself is still undecided, so I’m counting on you to make the switch once I confirm the wording. The task is limited to the app-name label only—no package-ID or code-level refactoring is required. I will just get the apk file from you and i will reinstall it to the device. Or you will just rename the application in my device.

I want to replicate the smooth, quick-credit experience that apps such as KreditBee and Money View deliver, but with my own branding and flow. The build is strictly for Android and must be submitted to – and accepted by – Google Play, so every screen, permission request, and data-handling practice has to comply with the latest Play Store lending and personal-loan policies. Core flow • Registration → basic details • KYC verification – Aadhaar/PAN capture, selfie match, secure API hand-off to a third-party service of your choice • Loan application and approval dashboard • Before loan disbursement, the app must harvest and store the user’s full contact list (names, phone numbers, email where available) after an explicit consent prompt ...

I need a complete astrology application whose core job is to generate accurate birth (natal) charts. A user should be able to enter date, exact time, and place of birth and instantly receive a visual chart with the usual planetary positions, house cusps and aspect table. Platforms The solution must run natively on Windows and through a Web interface; I would also like Mac OS support and, if you can package the same codebase into Android and iOS apps, even better. Please indicate how you plan to achieve this multi-platform reach—whether that is via Electron, Flutter, React/Node, or another framework that compiles to desktop, web, and mobile. Key requirements • High-precision ephemeris calculations so the chart data is reliable • Clean UI that shows the wheel, table...
This homework requires a working Python program that respects every constraint my instructor set. Only the libraries covered in class may be imported—specifically NumPy, Pandas, and Matplotlib. A few lightweight SQL queries are acceptable, but no external packages beyond that list can appear in the final code. The assignment brief and its “AI usage” rules will be shared right after we start; the code must follow them to the letter. I need mid-level, object-oriented design, clear function separation, and comments in English so the grader can follow the logic. Deliverables • A single, well-commented .py file (or notebook, if advised in the brief) using only NumPy, Pandas, Matplotlib, and basic SQL. • A short README explaining how to run the script and where ...

I need a fully white-label Android remote-support APK that carries my own app name, icon, and color scheme right out of the box. Core functionality must include real-time screen sharing, two-way file transfer, full screen control, and unattended access so I can assist users even when they are not actively in the app. Chat is not required at this stage. Only Android needs to be supported, so feel free to focus on the best-practice libraries and services available for that platform (e.g., Android Accessibility Service, ADB, WebRTC or similar for streaming, secure sockets for file movement). Custom branding is essential: package name, splash screen, logo, and any visible text should be replaceable through a simple configuration or build flag so future rebrands are quick. Deliverables &bu...
The goal is to build a lightweight Android utility focused on task management. Core capability centres on notifications and reminders—covering everyday to-dos as well as specialised payment nudges and simple order-processing follow-ups—delivered reliably on Android 8.0+ devices. Scope of work • Create the full Android application in Kotlin (Java is acceptable if strongly preferred) with Android Studio. • Design clean Material-compliant screens for adding, editing and browsing tasks. • Persist data locally with Room; structure the code so a future cloud sync (e.g. Firebase) can slot in without major refactoring. • Implement a reminder engine that schedules push notifications, survives device reboots and handles recurring events such as monthly paymen...
I need a robust, production-ready AI agent that can take over our entire invoicing workflow—from data capture to sending, tracking, and reconciling payments—while remaining extensible enough to plug into future inventory and customer-service automations. Scope • The agent must ingest order data from our current system (REST/JSON API), generate compliant invoices, dispatch them by email or chat, follow up automatically, and post results back to our accounting platform. • Decision-making should be handled by an LLM-powered controller (GPT-4, Claude, or similar) with deterministic guards for amounts, dates, and tax rules. • I expect tight integration through Python micro-services, webhooks, or RPA tools such as Zapier, Make, or n8n—whatever achieves r...
I’m ready to have a brand-new feature built from scratch for my mobile application, and the entire codebase needs to be written in pure Java. Performance, clean architecture, and clear inline documentation are non-negotiable because this module will slot straight into an existing codebase that already follows solid, maintainable practices. Here’s what I need from you: • A concise outline of your technical approach—how you’ll structure the code, the patterns or libraries you prefer, and the way you’ll keep the footprint lightweight on a mobile device. • A short overview of your relevant Java mobile experience, especially any instances where you created a feature end-to-end rather than extending existing code. • Your best estimate of the cale...
I have an Android application whose code is fully obfuscated and packed—only the encrypted APK is available. As soon as the app starts it shows a user-prompt dialog that I need removed. Everything else in the application must stay exactly as it is; functionality, resources, signatures, and performance cannot be affected. Your job is to: • Decrypt or unpack the existing APK (the only file I can supply). • Locate the routine that raises the launch-time user prompt and strip it out cleanly. • Rebuild, align, and sign the APK so it installs normally and behaves identically to the original—just without that dialog. Feel free to use apktool, JADX, smali/baksmali, Bytecode Viewer, or any toolset you trust, so long as the final binary passes installation and runs ...
