As Method

How I Ship with AI

Four principles behind every app I build solo.

Spec-driven

I write the spec. Agents write the code. I review every line.

Human-in-the-loop on architecture

AI accelerates the edges. I own the structure.

Tooling as leverage, not replacement

Claude Code, Codex, MCP — in service of shipping, not of looking busy.

Taste is the edge

Eleven years of iOS is what makes AI output shippable.
