How it started

The box was having no computer at all, at fifteen - my first programs written on paper, outputs imagined. Thinking outside it became the career: production systems that move real money - and the degree came after the practice, not before.

Core Foundations

01

End-to-end ownership

From first commit to the pager going quiet. If it breaks at 2am, I already know.

02

Product thinking

The brief is rarely the problem. Talk to users, read the tickets, then build.

03

Performance is a feature

Budgets before launch — not audits after. PWAs that feel native or don’t ship.

04

Always outside the box

Self-taught then, still self-teaching now — the toolkit below grows every quarter.
