Hi. I’m Matheus Cardoso! I’m a developer and Open Source enthusiast based in Brazil.

I’ve been a recurring speaker in international events such as AltConf in 2018 and 2019, and a recurring speaker at local and national events such as CocoaHeads, Pytalks and TDC, sharing knowledge and spreading the word about Open Source.

I was also a mentor for Google Summer of Code in 2018 and Admin in 2019, having attended the 2018 summit in Sunnyvale, California and the 2019 summit in Munich, Germany.
