Work with me
I’m a full stack engineer with 18+ years of experience building web products used by millions, and for the last few years I’ve focused on shipping AI/LLM features to production. I’m based in Santos, SP (Brazil), work fluently in English and Portuguese, and I’m open to full-time roles and selected contract work.
What I do best
- Product front ends and full stack delivery: React, Next.js and TypeScript on the front end; Node.js, Go and Java on the back end.
- AI-powered products: LLM integrations, retrieval-augmented generation (RAG) and agent-assisted workflows, from prototype to production.
- Architecture and team leadership: technical standards, code reviews and mentoring in distributed teams.
- AI-assisted engineering: daily use of Claude Code, Cursor, GitHub Copilot and Windsurf, always with review of every generated diff and tests as the safety net.
How I work
- Understand the problem first. I start from the user and the business outcome, check what already exists, and only then decide what to build (or not build).
- Small, verifiable steps. Tests and clear acceptance criteria before shipping, including for AI features.
- Clear communication. Short written updates, explicit trade-offs, and decisions people can follow later.
