How we work together.
A written plan, a shipped build, or ongoing product leadership — each scoped to where you are, with pricing you can see before we talk.
I look at what you've built or what you want to build and return a written plan you can act on — with me or without me. One document, real recommendations, evals, cost model. No deck theater.
I ship the thing. Production-grade software in your hands: scoped feature work, eval gates, monitoring, cost ceilings, fallback paths, and App Store review or the equivalent gatekeeper where it applies. Not a prototype. Not a "finish this with another agency."
Ongoing product leadership for founders who need a senior brain in the room. Design, AI infrastructure, and production discipline — embedded enough to make decisions, structured enough to not blow up your week.
Let's talk.
Thirty minutes. Bring what you've built or what you want to build — you'll leave with a real recommendation either way.
