How I work
Engineering with purpose.
01
Ship with intent
Every line of code ships to production. Write it like someone's business depends on it — because it does.
02
Complexity is a tax
Simple systems survive. I default to the simplest solution that solves the real problem, and add complexity only when the problem demands it.
03
Performance is a feature
Slow is broken. Speed, accessibility, and reliability aren't nice-to-haves — they're core deliverables on every project I ship.
