I’m a senior, full-stack software engineer with 20+ years of experience working on complex software intensive projects. I have a degree in Computer Engineering from PUC-Rio; and also have completed all CS Master's degree requirements from PUC-Rio & IMPA.

I'm currently leading the team behind the awesome Vectornator iOS/macOS app using Swift, SwiftUI, Combine, and Objective-C with some Machine Learning & Metal on the side ;)

I also did tons of C, C++, Lua, Java, Firebase, C#, JavaScript, HTML, CSS, Python, Mathematica, Bash, OpenGL, DirectX, and Unity development before that. My Upwork and AngelList profiles contains further details.

I currently live in sunny Rio de Janeiro, Brazil. You can reach me at paulo.rr.mattos at icloud dot com.
