From 191,300 reviews, clients rate our XML Developers 4.91 out of 5 stars.I run on PrestaShop 1.7 and I’m losing too much time pushing my supplier’s catalogue live. They already send me complete stock, price and image data in both CSV and XML; what’s missing is an automated way to bring that data into PrestaShop, map every variant correctly and fill in the blank descriptions with my own template enhanced by SEO keywords. Here’s exactly what I need built: • An importer (PHP/Symfony module or standalone script) that reads either the CSV or XML feed, detects new items or updates, and writes them into the right PrestaShop tables—products, combinations, images, specific prices, stock—without breaking existing IDs or URLs. • A simple description generator: the module should take my existing text template, inject produ...
Hello, I run a CBD e‑commerce website () on PrestaShop 1.7+. Manual catalog updates are slowing down my business. My supplier provides stock, prices, and images but no product descriptions. I am looking for a developer to create a custom solution that can: Import new or updated products from the supplier file (CSV/XML, later API). Map variants, prices, and images correctly into PrestaShop. Generate product descriptions using my existing template, enriched with SEO keywords. Provide a small back‑office screen where I can review or edit the generated content before publishing. Deliverables: A clean PrestaShop 1.7+ module or lightweight external script installed and tested. Admin interface for manual edits and one‑click publishing. Concise documentation (PDF or short video) for my tea...

I already have the unsigned XML, a valid X.509 certificate with its private key, the full specification, and the link to the government-run verification portal. Your job is to write clean Java code that adds the digital signature exactly as defined in the documentation so that, when I upload the resulting file to the official site, it sails through every check. I am flexible on the toolchain—Apache Santuario, Bouncy Castle, or the standard package are all fine—so long as the outcome is a fully standards-compliant, self-contained method (or small utility class) that I can drop into an existing Maven/Gradle project. The signed file must validate on both schema and signature levels, as the portal runs those tests automatically. Because this task is urgent, I need the finished c...
The website has no or limited referencing on the web search engine such as google. We are looking for a SEO referencing specialist to guide this mission of pointing all the products to google search engine.
Our internal ERP needs to pass data seamlessly to two accounting environments: QuickBooks Online for our U.S. books and Tally (India edition) for our Indian subsidiary. The integration must automatically move three data sets—Invoices, Inventory data, and Financial reports—without manual intervention. Key expectations • A two-way or scheduled one-way sync (whichever is technically safest) that creates, updates, and reconciles records across all three platforms. • Use of the official QuickBooks Online REST API and Tally’s XML/ODBC interfaces so future version changes are straightforward to maintain. • Clear field-to-field mapping documentation, error-logging, and a simple status dashboard inside the ERP or as a standalone web page. • Data inte...
I’m running WordPress 5.8+ and using WP All Import to bring a supplier’s XML feed into WooCommerce. The feed imports, but every Greek character shows up as gibberish. I’ve only used the plugin’s default settings so far—no custom add-ons or filters—so the encoding problem is happening right at import time. I need two clear results: • All Greek letters from the XML must display correctly in product titles, descriptions, and any custom fields after import (UTF-8 or whatever encoding proves correct). • An hourly cron job set through Plesk must re-run the import automatically and reliably. Feel free to handle the fix through WP All Import settings, a small code snippet, or server-side tweaks—as long as everything survives plugin updates a...

Overview I am looking for an experienced WordPress plugin developer (preferably with API/XML integration experience) to create a custom plugin that connects to the GoGlobal Travel API. API documentation: The plugin should import and manage static data (hotels, countries, cities), perform hotel searches, display results, show hotel details, handle booking, and finally insert bookings into WooCommerce Orders for payment processing and invoicing. Main Functionality Required 1. Admin Backend (Plugin Settings & Static Data) API credentials input (API key, username/password or token). Currency selection (API-supported currencies). Multilingual support (compatible with WPML). Import & update static content from GoGlobal’s static files: Countries Cities Hotels (basic info,...
I’m launching a white-label panel that allows end-users and resellers to recharge phones, pay DTH subscriptions, and settle utility bills through a single, well-documented API. A working demo of a similar recharge website or app is essential before we proceed, so please have one ready to share. The panel must: • Support Mobile recharge, DTH recharge and Utility bill payments end-to-end. • Integrate directly with mobile network providers, DTH service providers and utility service providers via secure API or XML/JSON feeds. Beyond those core requirements I’m flexible on the tech stack—PHP + MySQL, Node/Mongo, Django, or any robust alternative—so long as performance, security and scalability are demonstrated. Expected deliverables: 1. Web-based...
AI Conversation Engineer – SMS Logic + Industry Flows (No Voice Work) DESCRIPTION: We’re building an AI-powered texting system for businesses.

I am building a focused, lightweight utility application for Android phones and tablets. The concept itself is straightforward—one practical function delivered through a clean Material-style interface—but I want the execution polished and Play-Store ready. Development will take place in Android Studio; Kotlin is preferred, though Java is acceptable if you can justify the choice. The scope covers wireframes, UI implementation, back-end logic, and essential unit tests, followed by a signed release APK. Code must compile without errors on API levels 28 through 34, respect Google’s latest guidelines, and pass the Play Console pre-launch report with no critical warnings. Deliverables should arrive in three clear stages: 1. Interactive UI prototype (XML or Jetpack Compose) fo...
I need a self-contained mod pack for the current PC build of 7 Days To Die that both deepens the gameplay loop and expands the armory. The work is two-fold: 1. Gameplay layer • tune difficulty curves so the early game feels harsher and the late game stays challenging • add fresh, lore-friendly missions and quests—radiant or scripted—complete with rewards and dialog stubs • rebalance character skills to support the new quest lines and keep progression meaningful 2. Content layer • introduce melee, ranged, and crafting items that slot naturally into existing tiers (simple XML entries are fine where possible; custom meshes and icons when needed) The finished mods must be server side, not client side. If you have experience with Unity...
This project is an internal web application that will sit behind our firewall and serve several business units at once. I need a seasoned developer who can take it from database schema through deployment and hand-over documentation. Core functionality • Role-based access: at minimum Admin and Operator, with the ability to add more roles later • Multi-company tenancy so records stay completely isolated by company • Clean form screens that feed a well-structured relational database • One-click PDF and XML output from any stored record • Real-time dashboards for key KPIs and ad-hoc reports • Solid API layer that connects to payment gateways, CRM systems and our Facturación (electronic invoicing) provider Deliverables 1. Source code in a...
I have a fresh, legitimate copy of GTA V on my Windows PC and I want to turn it into a fully-modded experience. Specifically, I’d like vehicle mods, graphic overhaul mods, and gameplay enhancement mods all added and tuned so the game stays stable and performs smoothly. Your task covers both stages: installing the required mod managers/loaders (OpenIV, Script Hook V, etc.) and configuring every selected mod so they work together without conflicts. I’ll share any existing save files and give you remote access at a scheduled time; once the work is finished, I should be able to launch GTA V and jump straight into a mod-rich session with no crashes, texture pop-ins, or missing assets. Deliverables • Complete installation of the chosen vehicle, graphic, and gameplay mods &...
I’m looking to plug reliable Indian horse-racing data into my in-house analytics dashboard and need an API that can serve three key feeds: race results, real-time race updates, and detailed horse-and-jockey statistics. The service must pull data only from officially recognised Indian turf clubs and be stable enough for production use. I’m happy to consume JSON, XML or even CSV—whatever your existing platform provides—so long as the schema is well-documented. What I expect from you: • Secure, authenticated endpoints delivering the three data sets above. • Sample requests and responses plus any rate-limit information. • Clear onboarding instructions so my developers can start testing right away. If you already manage such an API, or can b...
I want a macro-enabled Word template (.dotm) that can automatically place a run of “---” dashes/lines whenever I leave empty space in a document. The logic is straightforward: clicking Start begins monitoring the cursor so each press of Tab or Enter lays down a clean, continuous dash line; clicking Stop pauses that behavior; clicking Delete Lines removes every dashed line the macro has generated. All three commands must sit in their own custom group on the Home tab. I’d like custom ribbon icons that match familiar functional symbols: Start, Stop and a Delete Lines. Deliverables • A signed, production-ready .dotm file with well-commented VBA code. • The ribbon customUI XML and any embedded icon assets. • A short read-me explaining how to attach the...
I want every product on our site to feel effortless to browse, compare, and purchase. The redesign should focus on user experience: cleaner layouts, intuitive navigation, and concise, persuasive copy that makes it obvious why each item belongs in the cart. Alongside the visual and UX overhaul, I also need our catalog to pull live stock and pricing from Vendor A and Vendor B while still showing our own inventory accurately. Whether you prefer API endpoints, XML/CSV feeds, or another reliable method, the final solution must: • display real-time availability and price changes from all three sources, • flag conflicts or duplicates automatically, and • allow my team to manage exceptions from the admin panel without touching code. Please send a detailed project proposa...
I need an AI-driven agent that can receive incoming webhooks, run the content through OpenAI, and then act on the results inside Kommo via n8n. My end goal is hands-off, real-time task execution, not just data display. The agent must reliably automate: • Data processing • Scheduling tasks • Triggering notifications Here’s the flow I have in mind: a webhook fires → n8n captures the payload → the agent calls an OpenAI model to interpret or enrich the data → relevant updates are written back to Kommo, calendar events are created, or notifications are dispatched, all in a single seamless chain. I’ll provide current n8n credentials, sample payloads, and the desired Kommo fields. You’ll design the workflow, write any scripts or functions n...
