AboutMe
The developer behind the code
I'm a senior fullstack engineer with over 10 years of experience and a post-graduate degree in Fullstack Development from Rocketseat. I work remote-first from Brazil (UTC-3), with real-time overlap with US business hours, and I've shipped 40+ products end-to-end - from interface design to database architecture, from payment integrations to AI-powered SaaS (RAG pipelines and LLM agents).
My journey started with HTML/CSS and PHP in 2014, evolved through React and Node.js, and today I work primarily with TypeScript across the entire stack (with Python for AI work). At Softplan, I lead frontend architecture for micro-frontend systems that serve Brazil's legal sector. On my own time, I build products that solve real problems: a worship platform used by church communities (Louvando.app), an AI sermon-prep assistant for pastors with subscription tiers (Arauto), an autonomous agent that verifies legal citations against official sources to fight GenAI hallucination (Lastro), and a political fact-checking platform (Fatos Eleitorais).
I'm also an open-source author and contributor - I publish reusable libraries (chord-transposer, react-chords, domain-events, an Evolution API Node SDK), and my work on Evolution API included caching optimizations that cut response times from 90s to ~400ms and database queries from 2h+ to ~20ms. My GitHub stays highly active year-round across TypeScript, Python and more.
