REST API Jobs

I’m building a net-new Salesforce application and need an APEX developer who can take it from concept to deployment. The core objective is to stand up a custom solution—not tweak standard objects—so strong experience writing scalable APEX classes, triggers, and Lightning components is essential. Here’s what I’m after: • Automated workflows – We’ll start by mapping the business processes together, then you’ll translate them into Flow or APEX-driven automations that run reliably at scale. • Custom user interfaces – Expect to design and code responsive Lightning pages/components that make the UX intuitive for end users. • Oracle API integration – The app must push and pull data to an existing Oracle system via RE...

I’m building a cross-platform mobile application for both iOS and Android and need a full-stack developer who is equally comfortable in Python on the backend and Flutter on the frontend. The core build will revolve around four key features: secure user authentication, real-time push notifications, a smooth in-app purchase flow, and a set of social-media style activities such as posting, liking, and basic feed interactions. On the server side, you’ll architect and code the REST (or GraphQL, if you prefer) API in Python, wire up the database layer, and make sure the authentication tokens sync seamlessly with the Flutter client. On the mobile side, you’ll design responsive UI widgets in Flutter, integrate platform-specific purchase APIs for both App Store and Google Play, a...

I am seeking an experienced Node.js developer to build a custom backend automation tool for an e-commerce marketplace. The system will handle two core automation components: dynamic price tracking and automated order fulfillment. Core Responsibilities: 1. Automated Repricer Engine: - Programmatically scan/parse public item catalog listings to track market price shifts. - Dynamically adjust my store's pricing based on target competitor rules (e.g., matching or undercutting). - Enforce a strict "floor price" matrix to ensure the system never updates a listing below cost. 2.

This project starts from a blank slate: I need a full-stack, production-ready business management web application that unifies ERP, CRM, inventory, billing and accounting features in a single responsive interface. Scope of work • Front-end: React.js with modern component architecture, state management and a clean, mobile-first UI. • Back-end: Node.js + powering a REST API that the front-end will consume. • Data: PostgreSQL for core transactional records and MongoDB for any unstructured modules; well-designed schemas and migrations are essential. • Core modules: customer relationship tracking, product & stock control, purchase/sales orders, invoicing, multi-stage accounting, plus an admin dashboard with real-time KPIs. • Security: JWT-based authentic...

CRM SaaS platform built on Laravel + Blade + + Tailwind CSS, with authentication, a database, and core infrastructure already live in production. We've had a full frontend prototype built out separately — a single interactive HTML file ( + Tailwind CSS) covering several major feature areas of the product, all fully clickable and functional against local browser storage. We now need a Laravel developer to wire this prototype into our real backend: real database tables, real API endpoints, real authentication, and real permission enforcement. This is not a from-scratch build. The UI, UX, and interaction logic already exist and work. The job is backend integration — designing the database schema, building the API, and connecting the two. Why This Should Be Faster Than a T...

We have a WordPress plugin that sells services on a CREDIT model. It is already CODED and already TESTED on a local machine: 31 of 33 smoke tests pass (the remaining 2 wait on OUR input data, not on defects) plus 6 of 6 payment-gate tests — including a real PayPal SANDBOX payment and refund. We need an experienced developer to take it onto a real staging domain and turn it into an accepted, live system: Stand up a fresh WordPress -> install & configure the plugin per the docs -> RE-RUN the provided acceptance suite on the real domain (30 smoke tests in M1; the 3 dataset tests complete the 33 in M2; plus 6 PayPal-gate tests) -> fix anything the real environment exposes -> go live on PayPal (one real transaction + refund) -> finish the operator docs ->...

I need a clean, reliable bridge built between our DonorPerfect CRM and DonorDrive (Bonterra) so the moment someone registers for one of our fundraising events, every relevant detail moves automatically into DonorPerfect. The DonorPerfect online API user manual is ready for you; DonorDrive also exposes an API and webhooks we can use. For each fundraiser we run, I have to keep three data streams perfectly aligned: attendee information, their donation records, and their event-registration status.

Instead, the existing ERP will serve as the primary functional reference, while the frontend is redesigned using a modern technology stack with an improved user experience, cleaner architecture, and significantly better performance. The backend will be developed separately using Laravel with PostgreSQL, and the frontend should communicate through REST APIs. During frontend development, dummy JSON data should be used for all pages and forms. Backend API integration will be completed later by our backe...

This project is a client–server solution in C# and .NET focused on endpoint (workstation) security. The client component runs on each workstation and enforces security policies locally, while all configuration is managed remotely through a web-based front end (front-end technology is your choice — required as part of the delivery). The server exposes REST endpoints for policy distribution, client status reporting, and centralized management. Expect modern .NET practices — dependency injection, async/await, EF Core for the data layer — with clean, layered architecture and thorough unit and integration testing. Deliverables Architecture and database schema documentation Workstation client, server, and web front end with full source code Automated test suite for cri...

My React front-end is fairly stable, yet the Node.js / Express REST layer that feeds it still trips over itself. Some endpoints lag, others throw inconsistent errors, and the authentication flow occasionally lets requests slip through untouched. Here is what I need from you: • Profile every REST route, identify the hotspots, and bring average response times back to an acceptable range. • Add (or tighten) centralized error-handling so callers always receive a predictable JSON structure. • Review the current authentication / authorization middleware, patch any logic holes, and make sure protected routes really stay protected. • Clean up any code smells you encounter along the way so future maintenance is easier. I exercise the API with Postman at the moment, b...

I need a full-stack specialist to take a social-networking concept from idea to a live, browser-based product.

Core functions include user sign-up/login, profile management, friend/follow mechanics, a dynamic feed, messaging, media uploads, notifications, and an admin panel. I’m open on tech choices, though modern stacks such as React or Vue on the front end and Node.js/Express, Django, or a comparable framework on the back end make the most sense. Whichever stack you recommend, clean code, unit tests, and clear documentation are mandato...

I need a seamless, real-time bridge between our Shopify storefront and our in-house ERP, ACME.

I need a lightweight .NET service that communicates with Epicor’s REST API and keeps our database and the ERP in lock-step. The core requirement is real-time data synchronization—changes made in either system should be reflected in the other within seconds, without manual intervention or batch jobs. Beyond simply moving records back and forth, the service must apply custom business logic before any write is committed. That logic includes: • Processing transactions – e.g., auto-generating related records, updating status fields, and posting to the correct Epicor endpoints. • Data validation – rejecting or flagging incomplete or incorrectly formatted payloads so we never pollute Epicor with bad data. • Workflow automation – triggering follow...

I’m launching a new online store and need it built from the ground up over the next six months. The core will be an e-commerce experience developed in WordPress and PHP, with a custom Laravel module where advanced logic is easier to maintain. Twilio must be woven in from day one for SMS order confirmations, two-factor log-ins, and, later, voice notifications. Because I don’t yet have a formal brand, the project starts with creating a cohesive identity—logo, color palette, typography, and the style guidelines that will inform every page template you code. Once the look and feel are approved, we can move into the build phase. Key milestones I have in mind • Brand identity package signed off • WordPress storefront and product catalogue live with payment gateway...

I’m building a small social-network site whose sole focus is letting people curate and share interesting links. The back end must run on Python 3 with Django; I’m happy with PostgreSQL for data, and you can keep the front end simple with Django templates or layer in React if that speeds you up, so long as it connects cleanly to Django’s auth system. What has to be in place: • Custom user profiles with avatar, bio and basic privacy controls • Two-way friend connections so users can follow each other’s link stream • Direct, real-time (or near real-time) messaging between friends • Link posts with title, description, tags and rich preview pulled via Open Graph • Feed, per-user timeline and quick search/filter Technical expectatio...

I already have a partially-working prototype for an industrial counter + timer built around an Arduino. It needs to count production units while tracking elapsed time in parallel, show both values on an LCD screen, and push the data over Wi-Fi to my factory LAN.
