Germán Fernández — Software Engineer

.welcome

I'm German, a 19 year old software engineer from Uruguay, now based in San Francisco. I'm a Founding Engineer at Terac, where we're building the infrastructure for the expert economy, and a Puentes Fellow at Antigravity Capital.

I'm curious about software, companies, finance, and people. I learn by building things and paying attention to what happens around them.
