Over mij
Zero to 30,000 visits a month on pure automation: an agent researches, writes and publishes every morning, and I approve it once. That's my own product, built end to end.
My code is merged at Expensify, a Featured Client here. Primary engineer on a public post-quantum protocol, 990+ commits. CTO, 8 years building software.
I build SaaS MVPs and AI web apps in Next.js, React, Node and PostgreSQL, AI agents and automations that run daily, and I rescue apps built fast in Lovable, Bolt or Replit. Auth, payments, admin, RAG chatbot, deployed, source in your repo.
