I'm Mario. I love building new things, especially if they're open source! Currently, I work for Lyft as a backend engineer within the routing infra team. If you're ever taken through a crappy dirt road, that was partly my fault, sorry.
My favorite topics are distributed systems and overall systems programming, for which I mostly use Rust, C++, and Python. Some noteworthy projects in my portfolio include:
Tremor
(Mentee)
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.
RSpotify
(Maintainer)
The most popular wrapper for the Spotify Web API in Rust. I helped improve its ergnonomics and safety.
NullDeref
(Founder)
This site itself! It’s open source and made with Hugo. You don’t truly understand something unless you can explain it to others :)
Vidify
(Founder)
Reproduces music videos for the music that’s playing on your computer, in real time. Supports Desktop, and Android phones and TVs.
Meme Stickers for WhatsApp
(Founder)
A very silly Android app that reached 5 million downloads. I wrote the first version, but I don’t own it anymore.
