Full stack engineer in João Pessoa, Brazil. I work on distribution and credit systems at PneuBras, and I am building the technology governance function there.
PneuBras. Microservices behind critical distribution operations across three product lines: Pneubras, Pneucommerce and PNBLub. Java, Spring Boot, Docker, Grafana, CI/CD. I helped structure the credit stack (Supplier and Liber) and the DEPS risk analysis, which together account for roughly 17% of company revenue. The company crossed R$1 billion in annual revenue for the first time in 2025.
Since February 2025 I also handle dev governance: formalising process, writing the technical documentation, and defining how the development team relates to the rest of the business. Right now I am founding a Technology and Innovation vertical, so that engineering sits in the strategy rather than in a ticket queue.
South Vale. My own consultancy. Senior software work for companies that need execution without building a team for it.
framebudget. Fit a video into a token budget for multimodal LLMs. Models do not watch video, they receive still frames, and the usual approach of grabbing one per second wastes money on repeated screens while missing anything shorter than the interval. This measures what changes and spends the budget there. Cut 47% off the cost of a screen recording with nothing distinct lost. Python, MIT.

Wisdom Imóveis. Data visualisation for real estate buyers and investors: market speculation, asset appreciation, fixed income comparison, and a discovery dashboard that pulled every listing in the city into one place. Sales rose 23%.
DBC Company. Started as a Java intern building REST APIs over Oracle, MongoDB, Kafka and PostgreSQL, then moved into the Salesforce engineering track.
