I build REST/JSON APIs that are easy to use and safe to operate: clear contracts, validation, pagination, rate limiting, authentication and error handling from the start. In Go or PHP.
Build REST/JSON APIs and backends.
Built production APIs for Cenoskop (product search and comparison), facha.sk (job marketplace REST API) and Paidshield (encrypted messaging API). Authentication, rate limiting, pagination and error handling from day one.
We agree on the API contract, build endpoints incrementally, and hand over documented, tested code. From €1,000 for a typical API.
Typical small-to-medium API. Complex scope is estimated after a quick discovery call.
Depends on your existing stack and throughput needs. Go for high-throughput/low-latency, PHP/Symfony if you need to reuse existing code and models.
