Hey, I'm Ryan \o_

Computer Science undergrad at University of São Paulo (USP) interested in software systems, distributed systems, infrastructure, and AI engineering.

My main interest is in building systems that coordinate things — users, machines, pipelines, and increasingly AI agents. And my main work sits somewhere between backend engineering and systems engineering.

Community & teaching

I'm involved with USPCodeLab, where I've worked on student software projects, technical courses, hackathons, and mentoring other developers.

I've taught and helped develop courses around web/backend development and I'm increasingly interested in teaching AI engineering and systems topics as well.

I enjoy building things, understanding how they work underneath, and sharing what I learn along the way.
