Two Decades of Code. Now Amplified by AI.

The Foundation

20+ years of hands-on engineering. Ruby on Rails since it was beta software. PostgreSQL since before it was cool. Led teams, split monoliths, integrated 15 payment gateways, presented 50+ live coding demos. The kind of deep expertise you only get by shipping real products at real startups.

The Multiplier

Now I pair with AI to build faster than ever. Not as a crutch — as a force multiplier. I write the rules that guide AI assistants (see ruly), architect the systems, and let AI handle the boilerplate. The result: startup-speed output with senior-engineer quality.
