About Me

I specialize in Golang, cloud infrastructure, GitOps, and CI/CD pipelines. Beyond code, I'm interested in startups and business topics — something I'm willing to explore more in the future.

Based in Poland, I focus on building reliable, maintainable systems and sharing knowledge with the developer community.
