Software engineer at the AI Lab of Folha de S.Paulo, Brazil’s largest newspaper, and a journalist by training. I design and ship the AI systems the newsroom and its readers use every day: pipelines, agents, a fine-tuned model and the apps around them, in Python and TypeScript. Based in São Paulo, open to remote roles.

CHASE
Automated monitoring rounds for the newsroom. Editors define recurring sweeps of competitor and social coverage; every article gets a summary and an embedding, a clustering job groups the last 24 hours into named trends, and a chat answers questions from the monitored content, with citations.
My role: Designed and implemented the current architecture and most of the features.
CORRETOR
Students write practice essays for ENEM, Brazil's national exam, and get an instant score on each of the five official competencies, with a written justification. The grading runs on a GPT model I fine-tuned with essays graded by the top-ranked prep school. Over 30,000 users.
My role: Led the project and fine-tuned the grading model.
DOLLY
A local-first tool that captures how a project is organized (layout, naming, toolchain, dependencies, conventions) as a small, portable pattern, then scaffolds new projects from it, checks existing ones like a linter and plans migrations as a dry-run diff. CLI, GUI and native app.
My role: Author. Designed and built end to end.
Earlier public work
Stanford Big Local News · 2024
An open-source Python scraper library and CLI that harvests police accountability records from California law-enforcement agencies, surfaced publicly through a Los Angeles Times collaboration. During my MA I designed and implemented the scraping plan for the LAPD data.
Estadão
A published interactive piece from Estadão, another of Brazil’s major newspapers, that maps robberies by street and neighbourhood in São Paulo from public-security data. I built the scraping and data formatting behind it.
Estadão
The coastal edition, mapping crime around São Paulo’s beach towns. Same role: scraping and data formatting.
