Over deze dienst

I build high-performance backends and APIs in Go engineered for scale, concurrency and reliability, not just to "work in a demo."


What I deliver: clean, idiomatic Go services; REST and gRPC APIs; database integration (PostgreSQL, MongoDB, Redis); authentication and middleware; structured logging and tests; and full source code. I also rescue and refactor existing Go codebases.


Stack: Go, PostgreSQL / MongoDB / Redis, gRPC & REST, Docker, Kafka/RabbitMQ where needed. 8+ years of backend engineering, 150+ projects delivered, 5.0.

Ideal for SaaS startups and teams that need a backend that holds up under real traffic.
