Interfaces built to perform,

Subject Profile

03 / 04

Not just interfaces. Systems that hold.

I care about the work underneath the surface — architecture decisions, component reusability, performance budgets, design system coherence. I've shipped across fintech, EV tech, DOOH, and HR platforms. I work closely with designers and can hold my own in Figma.

Currently freelancing from Berlin while finishing an MSc in Data Science at the University of Essex — which means I think carefully about data at the interface layer. I'm also a mentor at Girlcode Academy and have co-led developer communities for Ingressive for Good.
