Hello, I'm Matt!

I build fun stuff on the web, and sometimes write about it.

My name is Matheus Fantinel I'm a developer aiming to build things that
spark joy

I believe software should be great for everyone — those who write it and those who use it — and that bringing joy to problem-solving is the key to that.
