I'm Mario. I love building new things, especially if they're open source! I've recently graduated from University of Zaragoza, in Spain. My favorite topics are distributed systems and overall systems programming, for which I mostly use Rust, C, C++, and Python. The most notable projects I have worked on are:



An open-source event processing system written in Rust. My task was to implement a plugin system for it, and I have a whole series about it here.

The most popular wrapper for the Spotify Web API in Rust. I help improve its ergnonomics and safety.
