What to look for in a API Development freelancer
A strong API developer thinks about contracts, error handling, and the people who will consume the endpoints, not just the happy path. Look for:
- Clean, predictable endpoint design, with consistent naming and status codes.
- Real thinking about auth and security: tokens, scopes, rate limits, and input validation.
- Solid error handling, so clients get useful messages instead of silent failures.
- Documentation as a habit, not an afterthought bolted on at the end.
- Experience with your stack: Node, Python, PHP, Go, or whatever your backend runs on.
Ask a candidate how they version an API and handle a breaking change. The answer separates people who have maintained APIs from people who have only built them once.
