What I’ve worked on
Selected contributions
Microsoft Teams

Organizer & mentor

modern-frontend-architecture
Frontend architecture that survives real traffic: component boundaries, state that scales, and performance & accessibility budgets baked in from day one. The calls we'd make on day one, handed to your coding agent.
understudy
Point it at any URL and it measures the whole brand off the live page: colour, type, spacing, and the motion static tools can't see (durations, springs, stagger). It writes a design-model.yaml, then learns the feel on top.
