Solo studio · AI + Full-Stack

I ship production AI products. Solo, in weeks.

Twenty years building products for five million users. Now I run a one-person studio — designing, engineering, and shipping AI-native software on my own.

How I build

I treat shipping as the only signal that matters. Small batches, real users, fast feedback — and a refusal to scale code or process before the product earns it.

  1. 01 / Discover

    Understand the bet

    One week pinning down the actual problem, the audience, and the smallest version that proves it. No sprawling discovery decks — just sharper questions.

  2. 02 / Ship

    Build it small, ship it real

    AI-augmented full-stack work — design, code, infrastructure — taken from blank page to production in weeks, not quarters. Boring stack where it should be, novel where it has to be.

  3. 03 / Iterate

    Learn from usage, not opinions

    Once real users are on it, every decision is grounded in data and direct contact. I keep the loop tight: ship, observe, decide what to cut.

Capabilities

What I'm fluent in.

Twenty years across mobile, web, infra, and now AI. The list below is what I'll actually reach for on day one.

Ship LLM apps

RAG pipelines, agentic workflows, evals — and the boring infra to keep them honest.

Build full-stack

Mobile, web, backend, infrastructure — one person, one cohesive product.

Design cloud infra

AWS, GCP — boring where it counts, observable from day one.

Lead 0→1

From a fuzzy idea to a product real people use — without a team to hide behind.
