My name is Mario. I love learning, tinkering with systems, and trying to explain them! Currently, I work for Lyft as a backend engineer in the Routing team.
My favorite topics are distributed systems and overall systems programming, for which I mostly use Rust, C++, and Python. Some noteworthy projects of mine include:
Tremor
(Mentee, 2021 – 2022)

A high-performance Event Processing System. My task was to rewrite its core into a plugin system, which can be tricky in Rust!
RSpotify
(Maintainer, 2020 - 2023)

The most popular Rust wrapper for Spotify’s Web API. I rethought its design, enhancing ergnonomics and safety.
NullDeref
(Founder, 2021 – Present)
](/logo-small.png){kind=logo}
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, 2019 – 2022)
](/projects/vidify.png)
Reproduced music videos for the music that’s playing on your computer, in real time. Supported Desktop, and Android phones and TVs.
Meme Stickers for WhatsApp
(Founder, 2018 – 2019)

A very silly Android app that reached 5 million downloads. I wrote the first version, but I don’t own it anymore.
