API REST Jobs

I need a developer who can wire my existing eBay seller account directly into a custom application through the eBay REST APIs. The first priority is reliable product listing automation: pushing new items live, revising existing listings, and ending items when stock runs out, all through code rather than the web interface. Beyond listing, I also want full order-management coverage. Your integration should: • Pull fresh order details on a schedule or via webhook • Update order statuses (paid, shipped, cancelled, etc.) back to eBay • Handle return requests programmatically so I can approve, refund, or decline without logging in manually You may build in the language or framework you prefer—Python, Node.js, or similar—so long as the solution follows eBay&rs...

I need a full-scale web marketplace that mirrors the core experience of India’s GEM portal and MP Tender, covering both buyer and seller workflows in a single, seamless system. Buyer journey The front end must let buyers quickly search and filter the catalogue, line-up multiple items to compare specifications and pricing side-by-side, then track every order from placement to delivery through a clean dashboard. Speed and accuracy of search results are critical, so please propose the stack or indexing solution you trust most (Elasticsearch, Algolia, or your proven equivalent). Seller workspace Sellers should be able to log in and manage product listings end-to-end—add, edit, suspend, or delete SKUs—and reply to buyer questions in-app. Helpful extras such as sales ...

I have a fresh mobile project that needs to move fast and I’m choosing Flutter so we can ship a single codebase to both iOS and Android right away. The core screens and user flows are already sketched out; what I need now is a developer who can translate those wireframes into a clean, performant Flutter application, hook it up to the back-end APIs I provide, and get test builds onto TestFlight and Google Play Internal Testing without delay. You’ll start with a brief hand-off call where I walk you through the UI mock-ups, shared Figma files, and the existing JSON endpoints. From there, I’ll rely on you for: • Setting up a well-structured Flutter project (null-safety, proper state management, adaptive layouts). • Implementing the UI exactly as designed and mak...

The goal is clear: take the workflows I already have in production, uncover the bottlenecks and refactor them so they run faster, surface better analytics, and connect cleanly with the rest of the platform. Primary focus • We will be working on existing models rather than building from scratch, with Camunda Optimize as the main lever for insight and performance gains. • Within Tasklist, the pain point is integration with surrounding systems; I want assignments, hand-offs, and status updates to flow through our microservice landscape without manual intervention.

Build a property-ownership data pipeline — Montreal real estate (contract, milestone-paid, remote) I run a commercial real estate brokerage in Montreal. I'm building a private database that maps every multi-residential building in a neighbourhood to the people and companies that actually own it — including owners hidden behind numbered companies. You'll build the data pipeline and database from scratch. It has to be clean enough to grow for years. What you'll build Ingest Quebec open data (Montreal assessment roll CSV, Registre des entreprises bulk export) into Supabase / Postgres Schema: Properties · Entities (people + companies) · Links · Sources — keyed on matricule and NEQ, not address strings Monthly refresh that's idempote...

I’m building PayWave Namibia, a fully-featured mobile money and community-fundraising platform inspired by Cash App but purpose-built for our local market and regulatory landscape. The initial release must let users send and receive money, pay merchants via QR, and launch or contribute to fundraising campaigns, all wrapped in a sleek PayWave-branded experience. From day one the architecture has to revolve around compliance. Biometric authentication will be the primary sign-in method, backed by a configurable rules engine that enforces KYC, AML/CFT, sanctions screening, transaction limits and audit logging. Please design this engine so limits and policies can be updated from an admin dashboard without code changes; Namibia’s legal thresholds are still being finalised with the B...

I need a developer who can build a clean, reliable cPanel/WHM plugin that lets server owners route all outgoing mail through the TurboSMTP API. My servers run on Linux and I’d like to host the finished package so customers can download the installer, drop it into their own cPanel/WHM environment, enter their TurboSMTP credentials and start sending immediately. Core scope • Outgoing mail only: the first release just has to relay messages through TurboSMTP. I may revisit inbound handling later, so keep the code modular enough to add that without a rewrite. • Admin-only authentication inside WHM: the interface must respect existing WHM privilege levels—only root or reseller-level admins should be able to view or change the API key. • Seamless installation: an S...

Senior Full-Stack Developer — Production-Ready Data Intelligence Platform I am looking for an experienced senior full-stack/platform developer to take an existing data intelligence platform from its current development state to a secure, stable and production-ready product. This is not a greenfield build. A substantial application, architecture, database, frontend/backend and technical documentation already exist. The objective is to review what has been built against the intended architecture, identify gaps and technical debt, and complete the work required for production deployment. Platform Overview The platform is an enterprise data intelligence application that integrates data from customer business systems, processes and standardises it into a canonical data model, and prov...

I’m ready to move our educational institute onto a unified digital platform and need a full-stack Flutter developer who can deliver both sides of the product: • A cross-platform mobile app for Students, Parents and Teachers • A browser-based admin dashboard that keeps everything running smoothly Mobile app scope The core build must let users view real-time attendance tracking, check grades and upcoming assignments, and exchange messages with teachers. Each screen should adapt to the three in-app roles—Student, Parent and Teacher—so the right data and actions appear only where they belong. Admin dashboard scope On the web side, I’ll need straightforward user management (add, suspend, reset), flexible content management for notices or resources,...

I need an AI-driven recommendation system that studies on-site user behavior and serves up relevant products and content in real time on my website. The core job is to design, train, and deploy a model that can interpret click-stream, dwell-time, and purchase history data, then return ranked suggestions through an easy-to-call API or directly inside the site’s codebase. Here is what success looks like to me: • A behavior-based algorithm (collaborative, content-based, or hybrid—you can advise on the best fit) developed in Python using libraries such as scikit-learn, TensorFlow, PyTorch, or a framework you prefer. • A lightweight service—REST or GraphQL—that exposes “getRecommendations(user_id)” so my front-end team can drop it straight into...

I’m putting together a cross-platform mobile application that will run natively on both iOS and Android. To move the project forward I need a single developer (or a tightly-knit duo) who is equally comfortable building the UI in React Native and crafting a robust Java Spring Boot back end. The current project notes list “For Mobile Application Tech team” under required features; I’ll walk you through the product vision and we can refine the final feature set together during our first sprint-planning call. What I do know is that the app must feel fully native on each platform, share a single codebase wherever possible, and communicate with a secure, well-documented REST API you will also build. Key expectations • Set up the React Native project, implement sc...

I need a clean, reliable approval workflow that plugs seamlessly into both our existing web application and the companion mobile app. The flow is strictly for internal staff: a team member submits new-customer details, a manager reviews the record, and a final approver signs off before the account is activated. The core logic must: • Capture and store each stage (Initial submission → Manager review → Final approval) with full audit history. • Trigger real-time email or in-app notifications so no step stalls. • Expose REST/GraphQL endpoints that our front-end teams can call from React (web) and Flutter (mobile). • Respect role-based access controls already in our PostgreSQL DB. Deliverables I expect: 1. Database schema updates and migration scri...

I already have a working chatbot and chat system written in Python; now I want to transform it into a full-fledged customer-service agent. Its core jobs are clear: answer FAQs, process orders, and handle complaints or return requests. All of this must work seamlessly inside both my website and our upcoming mobile app. What I need from you • Review and refactor the existing Python codebase so it is clean, modular, and ready for production. • Strengthen the NLP logic so common customer questions are recognised reliably and routed to the right action. • Integrate order-processing and ticketing endpoints (they are REST/JSON) so the bot can create, update, and close orders or complaint cases. • Package the finished bot as an easily embeddable web widget plus a light...

I want to build the first release of a social media mobile app that gets the user-profile experience absolutely right. This milestone is all about secure sign-up / login, a clean profile page (avatar, bio, basic stats) and a simple search so members can find one another. Messaging and content sharing are on the roadmap, so please structure the code so those pieces can drop in later, but they are not part of this delivery. I’m flexible on stack—Flutter, React Native, or fully native—as long as the finished product runs smoothly on both iOS and Android and the codebase is well-documented. A lightweight backend such as Firebase, Supabase, or a REST service is fine; choose whatever lets you move fastest while keeping things maintainable. Deliverables • Complete source ...

Our product team in Hyderabad is ready to onboard a fresh graduate who can take full-stack responsibility for completely new application development, combining Java + Spring Boot on the server side with React on the client side. Day-to-day you will design RESTful endpoints in Spring Boot, wire them to a clean React interface, write unit tests, and commit everything to Git with well-documented pull requests. Skills to bring: • Solid academic grounding in core Java concepts and object-oriented design • Hands-on familiarity with React. If you are a Hyderabad-based fresher excited about owning features end-to-end in a collaborative, small-team environment, I look forward to working together.

I’m kicking off a new browser-based application and the very first milestone is rock-solid user authentication. I need a secure, scalable login and registration flow—think sign-up, email verification, password reset, and role-based access all wrapped in clean, well-documented code. You’re free to suggest the best stack for the job; I’m open to modern frameworks such as React, Vue, Angular or a classic server-rendered approach if it suits the project better. What matters most is that the authentication layer is bulletproof, follows current OWASP recommendations, and can plug into future modules without rewrites. Deliverables (initial phase) • Fully functional sign-up / login / logout workflow • Password recovery & email confirmation • Rol...

Our team relies on Odoo’s Sales, Inventory, and Accounting apps, and we’ve reached the point where the out-of-the-box setup no longer fits our workflow. I need an Odoo specialist who can: • Custom-tailor each of the three modules so screens, fields, and logic align with the way we actually sell, stock, and book revenue. • Integrate Odoo with our existing third-party tools (CRM, courier API, and a small in-house finance dashboard) so data flows seamlessly. REST and XML-RPC experience will be handy here. • Walk the core users through the revised environment, recording short how-to sessions so new staff can self-train later. Key acceptance criteria • All customisations survive standard Odoo upgrades. • End-to-end order flow (quote → invoice)...

I already have VJ_DOC live on Vercel and open-sourced on GitHub, but I now want to take it from “nice demo” to a polished, production-ready product. My first priority is feature enhancement, with a strong eye on smooth user flow. You will be working in a TypeScript stack (React on the front end, Node.js + REST API on the back end) and are expected to follow modern development practices, clean architecture, and secure file handling throughout. Core enhancement goals • Advanced file annotation that feels as snappy as native apps • Seamless e-signature integration, including signature capture, placement, and audit trail • Cloud-storage connectivity so users can pull from and save to services like Google Drive or AWS S3 without leaving VJ_DOC In parallel, I...

Our team relies on a fully custom-built CMS & CRM written in JavaScript/Node.js. It underpins everything from project and retainer tracking to sales pipelines, and it already talks to Gmail, Google Docs, and ChatGPT to automate daily workflows. I need a reliable technical partner who can step in whenever our in-house developer is unavailable, keep an eye on system health, and roll out small-to-mid-size enhancements we queue up. Think of it as light “on-call” coverage mixed with incremental feature work rather than a full-time rebuild. Core expectations • Proactively monitor the application, troubleshoot outages or performance drops, and deploy fixes with minimal downtime. • Ship new features or integrations on request—these could range from adding a ...

I’m ready to turn my existing REST API into a polished React Native mobile application. The API is fully documented and the screen designs are complete; what I need now is a clean, TypeScript-based codebase that follows good component architecture and stays as close to pure React Native as possible. Core requirements • Authentication: wire the app to my API using Basic authentication and persist credentials securely. • Navigation & UI: a tabbed interface that presents a master list (pulled from the API) and corresponding detail views, matching the provided Figma files pixel-for-pixel. • Offline experience: cache the entire app’s data locally so users can browse previously fetched content without a connection, with automatic background sync on reconnect...

I need a single Android application that brings three abilities together: • show the live HD feed from my existing IP cameras, • let me start / stop recording that feed and push the resulting files straight to my server, and • allow me to toggle an IP-based IoT switch from inside the same interface. A simple email-password login gate is required before anyone can use any feature. Once authenticated the user lands on a dashboard where the camera stream appears immediately; from there a record button begins saving footage and silently transfers it to my server (I will give you the endpoint and credentials). A separate tab or overlay houses the IoT switch with instant on/off feedback. I am open to whichever libraries you prefer—ExoPlayer, VLC, ONVIF, RTSP, MQTT, HT...

I need a brand-new web application built on SAP Business Technology Platform using the CAP Model. The solution will be delivered as a cloud service and must run smoothly inside the SAP BTP environment. Scope The project starts from a clean slate, so you will set up the CAP project structure, model the domain with CDS, and expose the required OData or REST services. A simple yet secure log-in flow is mandatory; the app must authenticate users against the BTP XSUAA service. Once inside, users should see intuitive pages that let them submit data through responsive forms and later review that information through clear, attractive visualisations (charts or tables rendered via SAPUI5/Fiori Elements or an equivalent modern JS charting library). Core deliverables • End-to-end CAP projec...

I’m rolling out the first customer-facing release of our U.S. start-up product and need a React specialist who treats testing and quality assurance as the heartbeat of every commit. Here’s the landscape Our REST APIs are live, wire-ready, and I have high-fidelity Figma screens waiting. Your code should translate those pixels into clean, reusable React components (hooks, context, TypeScript welcome) while keeping performance lean. Quality first Testing and quality assurance is the priority. I expect functional coverage across modern desktop and mobile browsers, with a mix of manual exploration and any automated suites you judge effective. Unit and component tests must guard critical business logic, and every sprint should close with a concise test plan plus a clear defect ...

I need a Flutter developer to build a polished mobile application that lets users browse available time slots and book consultation appointments from their phones. The app must run smoothly on both iOS and Android and communicate with my existing REST-based backend for everything—user authentication, schedule retrieval, booking creation, rescheduling, and cancellations. Here’s what matters most: • Clean, maintainable Flutter code that compiles for iOS and Android without platform-specific hacks. • Solid REST API integration with proper error handling and token-based security. • A straightforward flow where a user logs in, views consultant availability, confirms a slot, and receives an in-app and push notification of the booking. • Responsive, modern...

I need a solid backend written in Python that powers one-on-one messaging for an existing mobile chat application. The core tasks are to expose clean REST and WebSocket endpoints, handle real-time delivery, persist messages reliably in PostgreSQL, and keep latency low under moderate load. Authentication is already in place; your job starts at the moment the client is authorised. From there the service must: • accept text, emoji, and small attachment payloads • write each message atomically to Postgres, marking it delivered and later read • push live updates back to the correct recipient through WebSockets • expose a simple status route for health checks and basic metrics Unit tests that cover the message flow, delivery confirmations, and failure scenarios ...

I need a seasoned MERN developer who can take a business idea and turn it into a fully working, production-ready web platform. This is far beyond a simple CRUD site—I’m aiming for an end-to-end system that automates internal workflows, stores and processes data efficiently, and delivers real-time dashboards my team can rely on every day. Here’s what the work looks like: • React will drive a responsive, component-based interface that feels fast on both desktop and mobile. • Node.js with (or a comparable framework you prefer) will power a secure REST or GraphQL API, built with clear layering and strong typing where appropriate. • MongoDB will serve as the primary data store; I need well-designed schemas, indexing strategies, and aggregation pipelines ...
