Hi, I'm Diego

Fullstack developer

Fullstack developer with 6 years of experience building web applications. Background in Biological Sciences (BSc) and Ecology (MSc), bringing a scientific approach to analyzing and breaking down complex systems.

When I'm not at a keyboard, I'm probably with a cat, deep into a game, out somewhere in nature, or working through a reading list that keeps growing faster than I can finish it.
