01. about me

Graduated in Computer Engineering from Insper (SΓ£o Paulo), I believe the best way to validate an idea is to build it β€” then iterate until it's solid. If something sounds good, I prototype it in hours, not weeks.

My stack goes from Python and Node.js on the backend to Docker infrastructure and cloud deploys. I have experience with smart automations, algorithmic trading, and embedded systems.

In 2015 I ranked 93rd out of 1,604 contestants at the Brazilian Olympiad in Informatics (OBI), top 6% nationally. Today, I'm focused on building tools that generate real value β€” bots, automations, and projects that solve concrete problems.
