RESTful API Jobs

Front end work has already done. we need api work and laravel backend work. I’m expanding a React.js front-end and need a solid Laravel hand to wire it up to a clean, well-documented REST API. Your job is to build out the endpoints in Laravel, return JSON responses the React components can consume, and keep the codebase readable and testable as it grows.

I am expanding my in-house ERP and need a clean, well-documented API for several custom modules that sit alongside our existing inventory, HR, and accounting areas. The current system already exposes sandbox and production endpoints with separate keys, so your work must plug neatly into that dual-environment pattern. Core requirement: the new endpoints must handle user authentication using an API Key strategy. If you want to architect them so we can add OAuth2 or JWT later, that future-proofing is welcome, but for now the live build must rely only on API Keys. You will create the APIs and test the endpoints, then hand over concise documentation that shows other developers exactly how to hit sandbox versus production, obtain or rotate keys, and handle typical error responses. Deliverable...

We are looking to engage a senior-level software professional with strong expertise in interoperability solutions, particularly within healthcare systems. The requirement involves designing and implementing scalable integration solutions using InterSystems technologies such as HealthShare, Ensemble, or IRIS. The consultant should be capable of developing robust frameworks that enable seamless communication and secure data exchange between disparate healthcare systems, especially EHR platforms. Hands-on experience in building and managing integrations using HL7, FHIR, DICOM, RESTful APIs, SOAP, and JSON/XML formats is essential. The role will require close collaboration with cross-functional teams to understand integration requirements, design compliant architectures, ensure best practi...

1. Payment Gateway Optimization (Razorpay) Goal: Switch from manual UPI ID entry to UPI Intent (auto-opening apps like GPay/Paytm) or Turbo UPI. Action: Integrate the Razorpay Native SDK (not just a WebView). Scope: Implement this in both the Customer App (for order payments) and Delivery App (for wallet top-ups or security deposits). 2. Call Masking API Debugging Goal: Ensure privacy by masking phone numbers between Customers, Delivery staff, and Restaurants. Action: Audit current API integration across all three apps. Identify why errors occur during the "click-to-call" handshake and fix the state management handling the call triggers. 3. Dynamic Incentive Schemes (UI/UX) Goal: Display real-time earnings potential to drivers based on the new admin panel structures. Action...

I’m building out a new React front-end and now need the server side to catch up. The priority is a robust Node.js backend that exposes well-structured RESTful endpoints returning clean, predictable JSON. The data layer will live in MySQL, so you’ll design the schema, set up migrations, and write queries or use an ORM—whichever keeps performance high and code readable. Although Laravel experience is welcome and I do plan to introduce a small GraphQL layer later, right now your main focus will be the REST API: authentication (token-based), role management, pagination, filtering, and solid error handling. Clear inline documentation and a concise README or Swagger / OpenAPI file should accompany each route so the React team can plug in immediately. I’m flexible on tim...

About the Role As a Senior Fullstack Engineer, you will own the technical health and architectural evolution of mission-critical web applications. You will act as the primary anchor for robust .NET backends and dynamic React frontends, bridging the gap between high-performance server-side logic and modern user interfaces. This role requires an autonomous mindset to navigate diverse codebases, provide clarity through documentation, and drive technical excellence across the delivery lifecycle. Your success is measured by system reliability, the proactive management of technical debt, and your ability to mentor and elevate the engineering team. Key Responsibilities Fullstack Execution: Lead the development of robust architectures using .NET (Core/5+) and React, ensuring high performance, se...

I’m upgrading an existing e-commerce platform and the next milestone is a robust admin dashboard built with React, Tailwind CSS (plus the occasional Bootstrap helper), powered by a Java Spring Boot API backed by MySQL. Priority scope The public-facing site is already live, but the back-office tools are still thin. I want a dedicated dashboard that lets authorized staff control the whole store from one place. All admin routes will be secured with stateless JWT authentication. Core modules to deliver • User management – create, edit, disable users and roles • Product management – CRUD for catalog items, images, categories and inventory levels • Order tracking – view order history, status updates, refunds and fulfilment notes Technical expec...

We are seeking a highly experienced Senior Full-Stack Developer to design and build a scalable online tutorial streaming platform that enables creators to upload, manage, and sell video-based tutorials. The developer will be responsible for the entire development lifecycle, including system architecture, backend and frontend development, deployment, security implementation, and long-term maintainability. The backend architecture must be developed using both Python and Java, leveraging the strengths of each technology to create a robust, scalable, and high-performance platform. The system should support secure content delivery, user management, payment processing, and efficient content administration. The ideal candidate has strong experience with distributed systems, video streaming tech...

I run a RO-based tech agency and I need a technical partner to take over running it. This post is specifically for technical freelancers and consultants who've already been running their own show — winning clients, scoping projects, managing delivery — and want to do it with an existing agency, team, and client base instead of building from zero. If you're a developer or architect who outgrew just writing code and started running your own consultancy, managing clients, and subcontracting to other devs — this is your role. This starts as a freelance engagement with a 2-week paid trial. If it works, this becomes full-time with a base salary + commission on new business. Partner-track, not employee-track. You get: an existing team of developers, active clients, and...

We have an application based on Node JS . We need some work , intergration and ongoing work for it

I need a clean, well-documented Node.js solution that fetches JSON data from a specified API endpoint and turns it into a professionally formatted PDF made up exclusively of tables. The flow is straightforward: call the API, parse the JSON payload, map the fields to table columns, then render each table so it paginates gracefully and, when necessary, repeats headers across pages. Key points • Source data arrives solely from an API in JSON format—no manual entry or secondary feeds. • The PDF contains tables only; no images or free-form text blocks beyond table headers or footers you may add for clarity. • Any solid, maintained library is fine—pdfkit, Puppeteer, jsPDF, or a comparable Node.js toolset—as long as it supports custom styling (borders, alte...

Tenho um portal próprio construído em React e quero que ele converse de forma nativa com a API do Oneflow. O objetivo é automatizar processos para que o cliente final possa, dentro da área logada, fazer todo o ciclo de “entrar-verificar-assinar-acompanhar” sem depender de ações manuais do meu time. Cenário atual – Portal em React já publicado e com back-end Node. – Credenciais de API e documentação oficial do Oneflow em mãos. O que desejo automatizar primeiro Meu foco principal é o acesso do cliente final, permitindo que ele: • visualize documentos assinados, • consulte o status de cada contrato, • navegue pelo histórico de transaçõ...
