Matheus Cardoso
Software Engineer
I'm currently working at 4Selet and Zero7, and my biggest open-source project is at Abacate Pay. I care deeply about craft, detail, and making interfaces feel right.
Previously, I collaborated with Goiás F.C. and others. I curate playlists every month and run every day.
You can reach me on X and via email, or see my code on GitHub.
