About

I'm a curious geek interested in how technology works, math daydreamer and boardgame player.

I have 10+ years of experience with software engineering and data science, building performant and resilient systems with code, data and people.

You can check my open source projects in git.sitegui.dev and my personal blog in sitegui.dev.
