At Mais Pet, I built a corporate AI platform that automates internal processes, from intelligent-agent development through production deployment. I created LLM-based agents, RAG-style AI flows with LangGraph and LangChain, FastAPI APIs, and integrations across databases and cache engines.

At Wine, I led the end-to-end development of a WhatsApp-integrated communication and business automation platform. I drove architecture, business rules, full-stack delivery, UI/UX, infrastructure, external API integrations, and production monitoring.

At Jetsales Brasil, I built AI agents, n8n workflows, browser extensions, and Discord bots to automate sales cycles, lead management, and internal communication. These integrations reduced manual work and improved data reliability.

As a freelance developer, I've delivered web applications with Node.js, React, Java, Spring Boot, Docker, PostgreSQL, and MSSQL. I focus on scalable architectures, messaging patterns, cloud infrastructure, and practical automation that drives business value.
