03 — Built end to end

Things I’ve
actually built.

Not a portfolio of mockups. Two live builds you can open right now and use — design, front end and logic, all mine.

[ Hidden Patterns screenshot ]Live build 01Hidden PatternsFind the algorithm hiding inside three famous paintings. Watch the particles, guess the rule, then check yourself against the real one.Hidden-Patterns →[ Deep Patterns screenshot ]Live build 02Deep PatternsThe deeper follow-on. Build the algorithm yourself, work out why it scales the way it does, and find it operating in the real world — from weather models to zebrafish stripes.Deep-Patterns →

How I work

Use before look

The best idea in the world doesn't matter if people can't work out how to use it. Structure first, styling after.

Clean front end

Responsive layout and readable markup that loads fast, holds together on a phone, and stays easy to change later.

Tested for real

Both builds above went in front of real students in a real classroom. That's where you find out what actually works.
