Fast, Documented, Production-Ready APIs
APIs are how modern software talks. Whether you need a backend for your app, an integration between two systems that don’t natively connect, or a product API your customers can use, I build clean, fast, documented REST APIs in Python and FastAPI — for clients in the US, India, and worldwide.
What I deliver
- Backends for web and mobile apps — authentication, database design, business logic, deployment
- Integration APIs — bridge your internal systems, legacy software, or third-party services
- Data APIs — expose your datasets (including scraped data) as a product customers can subscribe to
- API rescue work — fix, document, and stabilize APIs that were built quickly and now cause problems
Every API I ship includes
- Automatic interactive documentation (Swagger/OpenAPI) your team can actually use
- Authentication and rate limiting appropriate to your use case
- Test coverage on the endpoints that matter
- Deployment to your infrastructure (VPS, AWS, Railway and similar) with monitoring
Why FastAPI?
It’s one of the fastest Python frameworks, with built-in validation and self-generating docs — which means fewer bugs and less time explaining endpoints to whoever integrates with them. I wrote a full comparison here: FastAPI vs Flask vs Django.
Frequently Asked Questions
What does a custom API cost?
Focused integration APIs typically start around $500–$1,500. Full application backends start from $2,000 depending on scope. You’ll get a fixed quote after a free scoping call.
How long does a custom API take?
A focused integration API: 1–2 weeks. A full application backend: 4–8 weeks depending on scope.
Can you take over an existing codebase?
Yes — I’ll review it first (free) and give you an honest assessment before quoting.
Do you handle hosting and deployment?
Yes, end to end — including CI/CD, SSL, and monitoring, on infrastructure you own.
What about GraphQL or webhooks?
Both supported where they fit the use case.
