Degree B.Sc. Computer Science,
Universidade de São Paulo

Currently Backend engineer at

Open to Backend and AI
engineering roles, or

genuinely interesting.
São Paulo, SP / remote.

Software engineer with a B.Sc. in Computer Science from USP and roughly a year of hands-on work shipping production AI systems. I tend to be most useful at the boundary between data, models, and production.

At Auria AI, an early-stage startup, I architect the database layer, data pipelines, and BI analytics behind agentic systems for B2B security incident triage.

My USP capstone was a Retrieval-Augmented Generation assistant for D&D Dungeon Masters, built with LangChain over a vector store of the official 2024 D&D Free Rules.

Hobbies.

Books, films
and Mandarin

This is what I do when the editor is closed, for anyone curious. Currently focused on reading classics and watching Wong Kar-wai and Park Chan-wook movies — I love a deeper storyline (which both have in common hehe). Also studying Mandarin Chinese on the side, i find it fascinating how challenging it is.
