What I'm looking for

I’m looking to lead production-grade agentic systems and full-stack products—where reliability, observability, and human review matter. I want to build scalable cloud workflows that automate real operations and prove impact with measurable cost and time savings.

I’m a Principal AI Engineer and Senior Full Stack Engineer with 11+ years building production software across AI automation and regulated domains like banking, legal, and healthcare. I design reliable agentic systems and real-world workflows using TypeScript, Python, LangGraph, LangChain, and human-in-the-loop review—backed by platforms used by 1M+ customers and systems that generated BRL 12M+ in annual operational savings.

Recently, I founded and lead Neurana, architecting agent orchestration, tool calling, structured outputs, and cloud execution infrastructure with queues, workers, retries, idempotency, and observability. I’ve also shipped 50+ client workflows that integrate APIs, browser automation, document ingestion, and AI analysis—reducing repetitive manual execution by up to 90% in targeted processes.
