Work
The short version of a long path — the ventures, teams, and projects that shaped how I build, most recent first.
-
Founder · São Luís, Brazil
My current chapter, and the one where the engineering and the entrepreneurship finally live in the same place. As technical founder I design and ship full-stack products across Next.js, Unity, C# and VR, while exploring how agentic AI can do real work for small businesses — not demos, but things people actually rely on.

Instructor · Remote
On the side, I taught. Through Ada's Google PrepTech cohorts I coached 40+ engineers preparing for interviews at Google, running interactive sessions on algorithms, data structures and system design and simulating the real thing until it stopped being scary. Teaching turned out to be the sharpest way to keep my own fundamentals honest.

Machine Learning Engineer · Remote, Brazil
The machine-learning chapter. At Reclame AQUI — one of Brazil's most-visited websites — I designed and shipped end-to-end ML with Python, Scikit-learn and FastAPI on Google Cloud. The one I'm proudest of is a real-time fraud-detection model that reached 92% accuracy, alongside a lead-recommendation system trained on 500k+ companies that quietly changed how the sales team prospected.

Senior Software Engineer · Remote, Brazil
Before the models, there was the backend. For three years I helped keep the 5th most-accessed website in Brazil healthy for 21M+ monthly active users, building scalable microservices with Docker, Kubernetes, RabbitMQ and Java/Spring Boot. The project that taught me the most was leading the migration off an aging EJB monolith — it cut our deployment overhead by roughly 80% and made shipping feel calm again.

Co-Founder & Game Developer · São Luís, Brazil
A detour into games, and a good one. I co-founded Trapcat to build mobile games and interactive prototypes, leading a small multidisciplinary team of designers and developers through scope, planning and deadlines. We took Quadra Monsters all the way from concept to the app store. More than anything, it taught me how to finish and release — not just build.
-
Co-Founder & CTO · Maranhão, Brazil
My first real startup. As co-founder and CTO I built a full-stack immigration platform in Django that grew past 15k users, while we tested three different business models — marketplace, Q&A and a step-by-step guide — hunting for the one that stuck. It was also my first taste of the Y Combinator application grind, and of how much I love the zero-to-one part.
-
Web Developer · São Luís, Brazil
Where I cut my teeth professionally. Full-stack web development with a build-anything-that-ships energy: a ticketing platform (cafufa.com) on Laravel, and a white-label real-estate CRM (aqueleimovel.com) on CakePHP, both backed by MySQL. Unglamorous, fast, and exactly the reps a young engineer needs.
-
Researcher · São Luís, Brazil
Where it all started. As a research intern at UFMA's Laboratory of Advanced Web Systems, I built a service-oriented P2P network with Java, SOAP, WSDL and XML. Distributed systems got their hooks into me early — I just didn't know yet how much of my career they'd end up shaping.
