Fellipe Souto

Senior Software Engineer | AI/ML & Systems Architecture

About

Nearly 14 years delivering production software across AI/ML, fintech, logistics, legal technology, SaaS and enterprise data platforms. I combine hands-on Python and Java with agentic AI, RAG and systems architecture, and I have spent years teaching what I build, from Caelum classrooms to university lectures at FIAP.
