Hi there!

I’m Claudio, a programmer from Brazil.

I’ve been writing code for over twenty years, mostly building web-based distributed systems for both public and private organizations.

I’m working with React and TypeScript, and occasionally with Node.js and Java.

At the same time, I’ve been reconnecting with my academic roots, exploring systems programming with C, Rust, and more recently, Zig. I also like to revisit computer architecture and operating systems.

Despite all the experiences I’ve had, I still feel excited about learning new things and sharing them with others. I strongly believe in learning in public. It’s one of the fastest ways to deepen understanding, gather meaningful feedback, and connect with others.

I’m also convinced that teaching is not only rewarding but also one of the best ways to grow and learn further.

This blog is my shared learning journal — a place to publish what I study and what I find useful. Hopefully, it will help others along the way, and also serve as a reference for my future self.
