Senior Software Engineer with 20+ years of experience building and operating reliable infrastructure. I care deeply about developer experience, platform reliability, and automating everything that shouldn't be done by hand — from bare-metal homelab to production at scale.
Currently working at Yazio, building platform tooling and internal systems.
