03 · About

Backend developer at Vatansoft.

I design and deliver scalable RESTful APIs, database models, and integration tools in Go, Docker, PostgreSQL, and Redis - using Echo, Fiber, and Gin, and leaning on goroutines and channels for concurrent, high-performance work. I structure codebases around clean architecture and a repository-service-handler pattern, and I'm comfortable owning CI/CD and Linux-based deploys end to end. I'm employed full-time at Vatansoft and also take on freelance backend work on the side.

Go
Echo, Fiber, Gin - concurrent APIs via goroutines & channels.
PostgreSQL
Schema design, query optimization, thousands of records at scale.
Redis
Queues, caching, callback/status tracking.
Docker
Dockerized deploys, CI/CD via GitHub Actions, Linux server management.

Get in touch.

Backend developer at Vatansoft, based in Istanbul, also open to freelance work - Go, PostgreSQL, Redis, Docker. Reach me directly on GitHub, LinkedIn, or email.
