(01) — Statement
I build complete systems for real operational problems — from the interface to the server they run on. Product decisions, architecture, real users, and interfaces careful enough that nobody notices the plumbing. Most of my projects started as an operational problem in a business I could actually walk into.

(05) — How I work
Four steps, one feedback loopObserve
Standing at the counter watching where the queue actually breaks—not asking anyone what they need.
Define
The workflow gets written before the stack does. Most ideas die here, which is the cheapest place to die.
Build & deploy
AI agents help with implementation. I own the requirements, architecture, integration, validation and the environment the system runs on.
Watch & revise
Real use is the test. I watch where people work around the system, then rebuild around what they actually do.
The judgement is the job. The typing is not.
