AI Engineering Lab

Design systems that people and AI agents can reuse.

Tokens, components and rules defined once for React, Angular, Vue, Swift and Kotlin, and published so agents can read them. Less repeated code, fewer tokens spent.

03About

I'm a Product Engineer with 5+ years designing and building digital products: web platforms, mobile apps and connected devices. I work across the whole loop, from research and UX to UI and design systems in Figma and production frontend in React, Angular and TypeScript, so ideas reach users without getting lost in handoff.

UX that starts with people

Discovery, user flows and high-fidelity prototypes for web and mobile. Today I lead UX/UI at Wellbeinn, across its mobile app, web and wearable.

Design systems that scale

Token-based component libraries adopted across squads and platforms: 30+ components, 35% less duplicated code and 30% fewer UI defects.

Fast, accessible frontend

Interfaces that perform on any screen: Lighthouse from 40 to 100 on critical flows and WCAG compliance from 30% to 95% in production.
