Engineering leader — Platform Engineering & Developer Experience. I build and grow technical organizations that make large engineering teams faster, and I like staying close enough to the code to know whether the strategy actually holds up.
Based in Tallinn, Estonia. 18 years in software, 12 of them leading teams.
I lead platform and developer-experience work: build systems, CI/CD, release health, and the engineering-productivity practices around them. My approach is to pair platform strategy with strong execution teams and let the metrics decide what's working. I've tracked developer-productivity data for over a decade and run primary research on what actually moves the needle.
