Building enterprise software at Prozis. Side projects and freelance work through Flavibyte.

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 working remotely from the US.
