RESTful Jobs

I’m refining an existing REST API and need a skilled developer who can jump straight into the current codebase and modify several endpoints without breaking backward-compatibility. The tasks in scope are clear: • Adjust the response data format so it’s consistent with our latest JSON schema. • Change specific request parameters—some fields are being renamed, a few are becoming optional, and one new parameter will be required. • Enhance the overall functionality of these endpoints, adding small but important business logic checks that currently live in the client layer. You’ll receive: – Postman collection and environment – Up-to-date API documentation (OpenAPI 3.0) – Access to a staging server plus a Git repo for pull reque...

I'm looking for an experienced backend engineer to develop a RESTful API.

The project’s front-end designs are already mapped out in Figma and the React codebase is in place, but the heart of the application—the .NET back-end—still needs to be built out and wired to multiple APIs. I need help turning that blank canvas into a secure, well-structured REST layer that the React client can rely on. Your main mission is to design and implement the entire server side in .NET (Core 6 or later is fine), then expose clean, versioned endpoints that cover: • User authentication and role-based authorization • Fast, reliable data storage and retrieval (SQL Server or a lightweight alternative—whatever fits) • All business-logic processing, kept neatly behind service interfaces Along the way we’ll be integrating three categor...

Our hospital-management platform is already running on Django and Django Rest Framework; the next milestone is full HL7 FHIR compliance. I need new endpoints and model work that cover patient management, appointment scheduling, medical-records access, inpatient and outpatient (OPD/IPD) flows, radiology & imaging, and billing—all exposed through a clean DRF API. The job touches every layer of Django: designing or refactoring models and database schema to mirror FHIR resources, wiring serializers and views for RESTful operations, and building or adjusting the HTML templates, forms, and server-side validation that staff will use day to day. A complete OpenAPI/Swagger schema should accompany the code so downstream systems can integrate without guesswork. Deliverables • Djang...

An API built in Node .js is required to pull detailed Instagram profile and audience metrics so they can be consumed by an existing platform. The highest-priority data points are followers, following, engagement rate, audience country, e-mail addresses, and city/state, followed by age, gender, fake-versus-real follower ratio, profile picture and post metadata. Engagement rate must follow the “likes + comments over a period of time” formula; please make the period configurable so I can test different windows later. The service should expose clear JSON endpoints, return clean, well-typed responses, and include concise setup instructions for deployment on a standard Node environment. Before final hand-off I need a simple document that flags any fields Instagram does not make...

I am building a bespoke payment processing system and need the core module that can accept both eChecks and ACH transactions seamlessly. The workflow must cover customer authorization, bank verification, and settlement within US banking rails. Alongside basic charge and settle flows, the gateway has to support two key features from day one: recurring billing cycles that I can configure by amount and interval, and real-time instant payment notifications so my application can update order status the moment a transaction changes state. Clear, well-documented webhooks or callback URLs will be fine for those notifications. Code quality and clarity are important because this module will plug into an existing SaaS platform. Please structure it as a self-contained REST API (language is flexible;...

I’m ready to roll out a minimum-viable e-commerce product that works seamlessly on both the web and mobile devices. The first release must let shoppers browse a product catalogue, add items to a cart and complete checkout through Stripe. I also need a lightweight admin area where I can create or edit items and review every order. Because inventory accuracy is critical, I expect strong protection against overselling under heavy traffic—database transactions or row-level locking are fine so long as stock counts stay correct. Whichever approach you choose, explain the strategy and make sure it scales. Stripe will handle payments, but I’m open to layering in other gateways later as long as automatic refunds and bank-level reconciliation remain intact. I prefer the front-en...

My web app is already live on Firebase Hosting and was built entirely with Firebase Studio. The last piece I need is a seamless Stripe checkout flow for one-time purchases. Here’s what I’d like done: • Connect my Stripe account to the project and store the keys securely in Firebase. • Create the Cloud Functions (TypeScript preferred) that generate a Stripe Checkout Session, listen for webhooks, and update Firestore with payment status. • Drop the frontend code into my existing React components so users are redirected to Stripe Checkout, then returned to a confirmation page once payment succeeds. • End-to-end testing in test mode, followed by a live mode hand-off with brief setup notes. Acceptance criteria – Customer can complete a singl...

I need a mid-senior developer who already feels at home inside API Routes and can wire them cleanly into a modern front-end. The core of the job is to build production-ready endpoints that cover full CRUD operations, secure them with OAuth, and connect everything to Google’s, Instagram and Tiktok APIs. Scope of work • Design and code REST-style API Routes in the /pages/api or app router (v13+) structure, following best practices for scalability and testability. • Implement OAuth flows end-to-end (consent screen, refresh tokens, secure storage) so every protected route seamlessly authorizes through Google. • Stitch the new endpoints into my existing front-end components, returning the exact data shapes they already expect. • Handle all CRUD actions&mdash...

create a RESTful API endpoint that Chipply can send daily JSON exports to, and YoPrint can pull those exports into their program.

Preciso que o fluxo de dados que hoje recebo em formulários preenchidos pelos usuários seja transformado, via integração de API, em PDFs de documentação técnica padronizados. O arquivo final deve trazer as especificações detalhadas que cada usuário informa e, em determinados casos, servir também para a criação de currículo no mesmo formato, usando a mesma base de informações. O que espero de você é um endpoint estável que receba o payload do formulário, componha o layout pré-definido (texto, cabeçalhos, possíveis tabelas e logotipo) e devolva o PDF pronto para download ou envio por e-mail. A lógica de template precisa ser fl...
