AI Engineer at Accenture building AI-integrated applications, and production agents for medical clinics at Auris.

Brazil
Message

At Accenture, I build and ship AI-integrated web applications end to end for clients in banking, insurance, and call centers. I work with TypeScript, React, and Python, alongside Docker, Kubernetes, Azure, and CI/CD pipelines.

At Auris, I build and maintain production AI agents for medical clinics, connecting LLMs to tools and APIs with MCP, REST, the WhatsApp API, and N8N. I use Claude, GPT, and Gemini to turn business processes into agents that work in production.

At Revelo, I reviewed LLM-generated Python code in production through human-in-the-loop evaluation and RLHF. I designed prompting strategies from real-world GitHub issues, tested edge cases and unsafe behaviors, and made final approval or rejection decisions on production pull requests.

At IXC Soft, I built conversational flows and AI logic for virtual assistants and resolved 86% of B2B support cases on first contact. Earlier, at Impulse Business Solutions, I built Power BI dashboards and SQL and Python ETL pipelines; in 2026, I also worked as a BI consultant at Active BI, leading three consultants on projects for four clients.
