Staff Software Engineer · Mountain View, CA

Hi, I’m Lorenzo.

I’m a staff software engineer who specializes in iOS, AI workflows and agentic coding, and cares about apps that feel fast and the platforms that let teams ship them.

I’ve led architecture, performance and platform work at Walmart, Care.com and Vizio, and for Hulu, HBO and Disney. Lately I’m happiest wiring AI into the way software gets built, tested and shipped.

I’m based in Mountain View, California.
