About

I'm a software engineer who learns by building. Most of my side projects start because I want to understand how something works — lately that's been AI tooling and RAG systems. I studied Computer Engineering at ISEP in Porto, Portugal, and I'm currently based in Centreville, VA, working remotely for Prozis (Portugal) as my first role out of college. Open to both enterprise codebases and startup environments.
