Founder & full-stack / AI engineer based in São Paulo, Brazil. I build AI agents and full-stack products that run in production — not demos.
I'm shipping a live multi-tenant SaaS end to end — 5 apps, a 443-endpoint REST API, and 14 AI features — solo. If you need someone who can take an LLM idea from prompt to paying users, that's the work I do every week.
- AI agents & LLM apps — function-calling agents across 12+ tool domains, with vision, memory, RAG, multi-LLM routing, provider fallback, and per-call cost logging + usage limits.
- Voice AI — realtime speech-to-text, meeting bots for Google Meet / Teams / Zoom, and LLM pipelines that turn meeting & site-visit audio into structured, human-reviewed reports.
- Full-stack SaaS — multi-tenant architecture (80+ tenant-scoped relations), RBAC, payments, e-signature, and mobile PWA.
