01. THE ENGINEER

Design Fidelity
& Code Precision.

I build the bridge between what designers dream and what browsers can execute efficiently.

Based in San Francisco, I help product teams build design systems that scale across platforms without sacrificing performance. My philosophy is rooted in clean, modular code, comprehensive testing, and pixel-perfect responsiveness.
