I help founder-led teams turn deep tech into clear decisions and momentum.
I run a small advisory practice where I work with founders, CEOs and CTOs on scaling engineering orgs, architecture and culture. Previously I spent 10 years in academia (computer architecture PhD) and 10 years in tech startups, supporting teams at Cockroach Labs (CockroachDB) and Neon on architecture, engineering culture and complex delivery.
What I optimize for: fewer, better decisions; safer scaling; habits that last.
Interests: product design, management, unix, dignified living, the history of computing.
