Adam Peña

I build high-performance UI infrastructure: accessible, battle-tested, and built to scale.

I've led front-end development at Cash App and Plaid, building experimentation platforms and UI systems used across teams. My work emphasizes performance, accessibility, and interfaces that hold up under pressure at scale.

I speak English, Spanish, and Japanese
