What I'm looking for

I'm looking to build AI-driven and backend systems where I can work on RAG, multi-agent architectures, scalable APIs, and software quality while continuing to grow as a technical leader.

At LACINA, in partnership with Dell Technologies, I built an AI-agent chatbot using LangGraph and FastAPI, cutting response latency by 70% with Redis. I also designed a HyDE-based RAG pipeline and benchmark, and I'm developing autonomous multi-agent systems to analyze codebases and address software vulnerabilities.

I've led backend delivery for ImobMatch, guiding a 14-person Scrum team while building a Java and Spring Boot REST API with PostgreSQL, Docker, AWS S3, and MinIO. As a UFCG academic monitor, I've supported students in databases, algorithms, object-oriented programming, and Python fundamentals.
