MY STRENGTH

I specialize in three things:

Research & design; I conduct user research, usability testing, and design end-to-end product experiences from wireframes to high-fidelity prototypes.

Design engineering; I translate Figma designs into pixel-perfect, production-ready components and build scalable design systems with consistent tokens.

Design systems; I build and maintain scalable design systems with consistent tokens, reusable components, and clear documentation that keep products coherent as teams grow.
