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.
Leading the development of a real-time risk management platform for treasury traders. High-performance, scalable architecture on AWS with Python, Node.js, and React.
Continued building the same platform after Sum Solutions was acquired by ItaΓΊ Unibanco.
Built the real-time risk management system from the ground up as a founding member. Full stack development β the same system that now serves ItaΓΊ's treasury.
