Claudia Alfonso

Hey, I'm Claudia 👋

happy you're here.

I've been a tech geek since I was a kid, obsessed with building things that look beautiful and actually work. Stuff people enjoy using.

This is my portfolio: a collection of projects I've built. I'm always up for a chat, and happiest when I'm building things with a-player founders.

Reach out if something sparks an idea.

Claudia in Silicon Valley

Always building. Always learning. Always up for a good challenge.

People person for early-stage startups, and for the moments when they're not so early anymore.

Over the last few years, I've helped startups build and scale their People & Talent functions from the ground up, without losing speed or quality.
