About

I have been writing software professionally since 2009 — starting with Java/JavaEE on ERP systems, settling into a long stretch in .NET, WPF, and modern web frontends, and gradually moving more of my time into cloud, infrastructure, and team leadership.

I find the most meaningful work at the intersection of business logic and infrastructure: modernizing legacy systems without drama, designing event-driven architectures that scale calmly, and building maintainable interfaces that engineers actually want to work with. I default to thinking in trade-offs, writing down the why, and reducing surprises in production.

AI-augmented engineering

AI-augmented coding has moved from experiment to a daily part of how I work. Claude Code and Codex are tools I use to design, refactor and ship production code through agentic workflows — while staying responsible for the architecture and the trade-offs.

Off-screen

Active member of the local volunteer fire department, and a serious fan of the mountains — hiking, via ferrata, and skiing. The reset that keeps the screen-work clear.
