Bio · background
· current focus

Name Luiz Carlos Costa da Silva
Software Engineer

Based São Paulo, BR

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

Currently Backend engineer at
Auria AI — agentic AI,
B2B security triage.

Open to Interesting problems,
considered collaborations.

Software engineer with a B.Sc. in Computer Science from USP and roughly a year of hands-on work taking AI products from zero to one. 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.
