About

Backend Engineer based in Wrocław with nearly two years of DevOps and SecOps experience. Currently finishing my Master's in Cybersecurity while building Node.js applications professionally.

I started in web development, hit the same pain points every developer knows, and moved into DevOps to fix them. Now I'm back writing code — but with a solid understanding of what happens after the commit. I like reliable systems, clean automation, and the many smart devices running in my apartment.
