Profile

Hi! I am a Software Engineer (MSc) with 12+ years of experience and a passion for leading teams to build reliable systems for high-potential applications. Tokyoite since 2014 and not afraid of flying.

I love designing and implementing systems that produce measurable value to their stakeholders. I also like a bunch of other topics that help me keep an eye on the wider picture: delay-tolerant networking; distributed and fault-tolerant systems; data compression; compilers and runtimes; machine learning and data mining; information visualization and user-machine interfaces; policy and IP. I believe in the power of open source and its communities.
