I’m building a new system that will expose data-retrieval endpoints and need a developer who can architect, code, and document a clean REST API from scratch. The service will be read-only for now—its sole responsibility is to accept requests, query the underlying data store, and return well-structured JSON responses with minimal latency. Here’s how I see the engagement: • Scope – Design the endpoint structure, query parameters, and error-handling scheme. – Implement the API using a mainstream framework you’re comfortable with (Express, FastAPI, Laravel, Spring Boot—your call, as long as it’s maintainable). – Connect to an existing relational database; I’ll provide schema details and sample data. – Add pagination, basic rate limiting, CORS configuration, and concise logging. • Deliverables – Source code in a private Git repo. – Postman (or similar) collection covering every route. – OpenAPI/Swagger spec for self-service onboarding. – Brief deployment guide for a Linux server (Docker welcome). – A short hand-off call or video walkthrough once everything is running. • Acceptance criteria – All endpoints return the correct payload in under 300 ms on local tests. – Unit and integration tests achieve at least 90 % coverage. – No critical issues flagged by static analysis or security linters. If you’ve built high-throughput, read-only APIs before and can turn this around quickly, let’s discuss timelines and next steps.

With a decade of experience building high-performing APIs, I am confident in my ability to architect, code, and document a clean REST API perfectly suiting your needs. Having worked extensively with Java and PHP in service development frameworks like SpringBoot and Laravel, I understand the importance of ensuring your new system is maintainable for long-term success. My experience in handling relational databases aligns well with connecting to your existing schema. In my past projects, I've always focused on extensive unit and integration testing leading to high coverage which I have no doubt will continue into this project. Additionally, static analysis and security linters would remain a crucial part of quality assurance throughout development. All this contributes to building an API that is both fast (under 300ms) and highly secure; two aspects that are paramount for any successful API. With my skillset and commitment to delivering quality work, we can turn your vision into reality. Let me help you build this solid foundation for your system that will perform-readily now & scale willingly later.

You need a clean, read-only REST API built from scratch: well-structured JSON responses, low latency, sitting in front of an existing relational database, with the production niceties (pagination, rate limiting, CORS, logging) and proper hand-off material so anyone can pick it up later. That last part is where most of these projects fall short, so it is where I focus. You get the API, but you also get the OpenAPI/Swagger spec, a Postman collection covering every route, and a short deployment guide for a Linux box (Docker included), so onboarding is self-service rather than a series of questions back to me. On the stack: my strongest is ASP.NET Core Minimal API, which gives you fast, low-allocation request handling and first-class OpenAPI generation out of the box, comfortably under your 300 ms target. That said, the framework is your call. If you would rather stay on FastAPI, Spring Boot, or Laravel for maintainability reasons on your side, I will match it without changing the price. How I would run it: Milestone 1 (design): endpoint structure, query parameters, pagination model, and the error-handling scheme agreed with you before any heavy coding. You sign off on the shape first. Milestone 2 (build): all endpoints wired to your database from the schema and sample data you provide, plus rate limiting, CORS, and structured logging. Milestone 3 (hardening and hand-off): unit and integration tests to your 90 percent coverage bar, a clean pass through static analysis and security linters, the OpenAPI spec, Postman collection, deployment guide, and a walkthrough once it is running. I have built read-only APIs against existing schemas before, so the unknowns here are your data shape and your latency-sensitive routes, both of which we nail down in Milestone 1. Send the schema and a couple of representative queries and I can confirm the endpoint design quickly.

Hi, This project aligns well with my experience building production-ready APIs focused on performance, maintainability, and clean documentation. My approach would be to first design a clear API contract—including endpoint structure, query parameters, pagination, error handling, and response formats—before implementing the service using a modern framework such as FastAPI or Express, depending on your preferences and deployment environment. What you'll receive: • Well-structured REST API connected to your existing relational database • Pagination, rate limiting, CORS, and request logging • OpenAPI/Swagger documentation • Complete Postman collection for all endpoints • Unit and integration tests targeting high coverage • Dockerized deployment setup and Linux deployment guide • Clean Git repository with organized code and documentation • Handover session to walk through architecture and usage I place a strong emphasis on performance, security, and maintainability, ensuring endpoints remain fast, predictable, and easy to extend as your platform grows. I will document it properly so you can maintain it with AI. I can start immediately and would be happy to discuss the database schema, expected traffic, and timeline to provide an accurate delivery estimate. I would also like to know the number of APIs that needs to be built. Cheers, Apoorv

Hi, I understand that you're not looking for a full application but a well-architected, high-performance read-only REST API that can serve data efficiently from an existing relational database. For this project, I would recommend FastAPI because it offers excellent performance, automatic OpenAPI/Swagger documentation, strong validation, and is very well suited for low-latency APIs. My approach would be to first review the schema, design clean endpoint structures and response standards, then implement pagination, filtering, rate limiting, logging, and error handling consistently across all routes. Planned deliverables include: • REST API source code in a private Git repository • OpenAPI/Swagger documentation • Complete Postman collection • Unit and integration tests with high coverage • Docker configuration and Linux deployment guide • Final walkthrough and handoff session Estimated timeline: 1. Architecture & endpoint design – 1 day 2. API implementation – 3 days 3. Pagination, rate limiting & logging – 1 day 4. Documentation & Postman collection – 1 day 5. Testing & deployment preparation – 2 days Total: approximately 7–9 days. I have experience building database-driven APIs with a focus on performance, maintainability, and clean documentation, and I'd be happy to discuss your schema and expected query patterns before we begin. Thanks & Regards, Bhupender
