Sobre Mim

Anyone can vibe code — I design the agents. I build closed-loop AI systems that ship entire apps, run code autonomously, and serve as custom workers for businesses. Currently Agent Engineer at Spring Global, where I lead GenAI initiatives including agent factory development, RAG pipelines, vector databases, and multi-agent orchestration. Featured in Spring Global's blog for building an AI agent that replaced a $100k SaaS proposal.

I design agents at every scale — from an enterprise behavioral AI that nudges employees into compliance, to a Telegram bot that serves as a carpenter's personal accountant. Using Claude Code, Claude Cowork, and custom MCP servers, I architect closed-loop systems that eliminate 90% of manual work and keep running without me.

Based in Florianópolis, currently contracted full-time through June 2026. Limited availability for select projects. My stack: whatever solves the problem best, AI-first. Fluent in Portuguese and English, conversational Spanish.

I Invested in Hunter's startup, and have been helping out as CFO for some time. He is extremely self-motivated and a very hard worker. We have also been friends for many years and he has always been this way. Always grinding and exemplifying discipline on a level that most do not. I invested in him not only because I believe in the idea, but more so because I believe in him to make it happen.

Hunter is a high energy full stack dev and comes highly recommended. I hired him to help me build out an MVP of a web app idea of mine with some very tricky backend requirements and he performed well, even when I was too busy to supervise closely or give sufficiently detailed instructions. He's very smart and a very good communicator with a good sense of software craftsmanship. You're advised to hire him now before I book him again for my next round of work!
