Hi, I'm Marcello

I sketch interfaces and systems: type, spacing, motion, the details people feel before they notice.

How I work

About

I'm a Design Engineer and Product Engineer with 8+ years of experience. Today I'm a Senior Design Engineer at Xata, a Postgres platform for AI workloads. Before that I co-founded Stackzero, where I led product and design and shipped an API, an admin dashboard and open-source UI libraries used by thousands of developers.

Projects
