I studied Computer Science and Engineering at Instituto Tecnológico de Buenos Aires. I'm originally from Argentina, currently living in Uruguay.

My work is related to cryptocurrencies, distributed systems, machine learning, interactivity, and robotics. My goal with tech is to bring new experiences to people.

I cofounded and was formerly CTO at OpenZeppelin. Currently, I'm studying music, biology, artificial intelligence, and 普通话. I'm also interested in investing and helping out early stage tech explorations.

Miscellaneous interests

  • Indie games, especially Braid, a game about time and causality that showed me that videogames can be as deep and enjoyable as books, music or art. Other games I enjoyed a lot are osu!, Today I Die, Undertale and The Witness.
  • Esports, or competitive play of videogames. I once trained and played in Starcraft 2 tournaments. Valuable resources for learning were Sean Plott's Day[9] TV and Shaun Clark's Terran Tutorials. More recent, Vibe's Bronze to GM series are an amazing way to get better fast, focusing on fundamentals. Lately, I've picked up Legends of Runeterra, a card game by Riot Games, and I'm hoping to get better.
  • Creative Coding, or making art via code. I've seen some mind-bending examples like this fantastic video from FITC Tokyo 2015, or the paintings of StyleNet.
  • Educational Videos on YouTube. My favorite channels are Kurzgesagt, Vsauce, Vi Hart, PBS Spacetime and theodds1sout.
  • Music. I play some guitar, bass, keyboard, trumpet, flute and algorithms! I've recently ventured into EDM production. You can find my tunes in my soundcloud profile.
