I’ve been in tech for over 15 years, worked on everything from telecom infrastructure to backend and DevOps for high-load systems. After serving in the Armed Forces of Ukraine, I’m now fully focused on getting back into tech and contributing long-term. I value straightforward communication, reliability, and solving hard problems.
