About

Backend engineer with a focus on Go, Python, and TypeScript. I build enterprise-grade microservice architectures — from gRPC contracts and event-driven pipelines to Kubernetes deployments.

I ship end-to-end: Docker, Kubernetes, GitLab CI/CD, Traefik, Cloudflare. Infrastructure is self-hosted, including my own private GitLab instance for production projects.
