Hi, I'm Ronaldo.

I build software, ride bikes, blunder at chess and cook ambitiously.

Full-stack developer based in Uberlândia, Brazil. I like turning vague ideas into things people can actually use.

About

Half developer, half hobby collector.

I'm a full-stack developer, fluent in C# and JavaScript. I started out on the backend and quickly fell for the frontend and all the cool things you can do with it.

Away from the keyboard I ride my bike, play chess and cook chef-like meals. Results vary, enthusiasm doesn't.

I try to leave things a little better than I found them, and to get a laugh or two out of the people around me.

Work

Things I built, some of them on purpose.

A mix of client work and side projects. Want details on any of them? Just ask.
