APIs with a clear contract, ready for another team to use
When one system needs to serve several applications — web, mobile, or third-party systems — the API is what connects them. I build RESTful APIs with consistent endpoint structure, uniform response formats, and clear error handling.
Every API I hand over comes with documentation covering the endpoint list, parameters, sample requests, and sample responses — so another team can start using it without guesswork.
I also handle authentication, per-role access control, and adding an API layer to systems that are already running but have no programmatic interface.
