How I work
Four habits, each with a case to prove it.
- 01
Complex in, simple out
I map every edge case, then cut the model down until the common path takes one decision.
TrueProfit - 02
Evidence decides what ships
Funnels, heatmaps and usability tests shape the design, and I measure again after launch.
Vieclam24h - 03
User need × business need
Every screen has to earn trust from users and move a number for the business.
PayME - 04
A designer who ships code
I prototype in real code with Claude, Codex and Gemini, and validate before asking engineering.
