Catalin Irimie.

Engineer, hacker, entrepreneur. Drawn to complex systems and the interesting ways they fail.

I spent years keeping distributed systems honest: disaster recovery and cross-region replication on GitLab Geo, PostgreSQL when it hurts, infrastructure that has to survive its operators. These days I build my own things.

Also curious about cybersecurity, macroeconomics, and the human mind, roughly in that order, depending on the day.
