What I'm looking for

I'm looking to build backend and generative AI systems that automate engineering workflows, improve SDLC efficiency, and solve complex problems in scalable, resilient environments.

At Bradesco, I build AI-agent and LLM systems with LangChain4j and Spring Boot to automate complex engineering workflows and improve SDLC efficiency.

I develop Retrieval-Augmented Generation pipelines using vector search and semantic indexing, improving contextual retrieval and agent response accuracy. I also integrate agents with Test Data Management platforms and Jira to automate test-data provisioning.

Previously at Bradesco, I built Java, MS SQL Server, and Apache Kafka services for a hybrid AI-and-human customer support platform across WhatsApp and mobile channels. At Tribanco, I developed merchant portals and BFFs for the Única ecosystem using Angular and Spring Boot REST APIs.

I've also built a scheduling platform with JWT authentication and SQL persistence, plus a NASA Hackathon RAG Q&A prototype using Python, embeddings, and vector search.
