About

I've been building on the web independently since 2016.

I work end-to-end on the products I take on — from the database schema up through the UI a customer actually touches. Most of my recent work has been React and Node.js applications for founders who need a technical partner, not just a pair of hands. Lately I've been building AI agents, workflow automation, and MCP servers for teams that want to move faster without hiring.

I care about the boring things: sensible data models, observability, performance budgets, and code that the next developer can read without cursing. If any of that sounds like what you need, I'd like to hear from you.

How I work

Three things I keep coming back to.

  1. Ship small, ship often.

    A working slice in production beats a perfect plan on a whiteboard. Iterate against real users, not imagined ones.

  2. Instrument before you optimize.

    Logs, metrics, and traces from day one. You can't fix — or brag about — what you can't see.

  3. Boring stack, sharp fundamentals.

    Postgres over a fashionable database. Clear data models over clever abstractions. Fewer moving parts, fewer 3 AM pages.
