    // About

    Eduardo Dionisio Fernandes. 20+ years in C++ — from real-time embedded systems to distributed trading platforms. Based in Brazil, working remotely for global teams.

    I built Code Royale — a multiplayer coding battle platform — and maintain open-source projects across Go, TypeScript, and Python. I share daily on X where 8K+ developers follow my work. I believe in conscious C++: knowing what happens between your code and the silicon.
