About
I'm a software engineer in São Paulo. I've been writing code since I was 12 and working with it since high school. Before code came maths: I spent a good part of school solving olympiad problems, and that's where my most-used habit comes from, breaking the problem down before writing the first line.
Today I look after the AI layer and the system design of Lean Saúde's products. In practice that runs from agent pipelines to identity and access architecture, and goes through one rule I take very seriously: sensitive data doesn't reach any model without being masked first.
Outside work I keep two products of my own running, Tô Com Entulho and Crypto Forense, and I study Systems Analysis and Development at FAM. I like teaching too: Load Simulator was built so teachers can show a bottleneck in front of the class, and it's open source. The rest of the time it's specialty coffee, jiu-jitsu and lots of books, as the shelf shows.
Experience
2025–now
Lean Saúde
Senior software engineer, applied AI. I look after the AI layer and the system design. I rewrote the company's first system, from PHP and WordPress to Next.js and microservices, and today it analyses more than 2,000 medical cases a month with AI. I also designed the ReBAC/RBAC permissions, inspired by Zanzibar, and the single sign-on for every system.
2023–2025
Skyward Tech / DEX
Full-stack engineer. I rebuilt Unimed's OPME hubs, which became five times faster, in a purchasing programme that has already saved R$ 419 million. I also led an agribusiness management platform from scratch, from the concept to companies using it all over Brazil.
2022–2023
BRA
Mid-level full-stack developer. The company's two core systems, in Laravel and Vue: the one for customers, handling thousands of sales a day, and the internal panel. Lots of queues, caching and well-written queries.
2021–2022
Midnight Esportes
Junior front-end developer. My first job. I worked on the supplements e-commerce and its admin panel from start to finish, in React and Node.
Highlights
OBMEP finalist four times, in 2017, 2018, 2019 and 2022, and gold at CUCO, the competition run by the São Carlos Institute of Physics (USP), in 2023. My teachers and the school's maths olympiad group are largely to blame.
