A picture of me

My name is Mario. I love learning, tinkering with systems, and trying to explain them! I'm a big fan of adventures around nature, so Munich is an awesome place to live!

Currently, I work for Lyft as a backend engineer in the Routing team. Other 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 is quite 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)

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)

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 and later on sold it.

If you want to contact me, you can schedule a chat or use any of these links:

Note: “Ortiz Manero” are both surnames, not middle names! It's how we go in Spain: they come from my father and mother, respectively :)
