I build products.
I write about it.

A decade of building products at scale — from crypto exchanges to product studios. I write about what I've learned, and I take on consulting for founders who want to move faster.

Work with me

Sprints

2–4 weeks, one goal, zero fluff. We scope it, build it, ship it. Then you buy me an espresso. That's the deal.

Ongoing

I embed in your team as fractional product lead. We ship together. You forget I'm a contractor. (That's the goal. Also: I expect snacks.)
