What I'm looking for

I'm looking to build secure, scalable full-stack, cloud, and AI-powered systems, contributing from requirements and architecture through deployment, quality, and production support.

I've built and supported banking, education, document-management, archaeology, and customer-service platforms for Stefanini, 4Quality, Poupex, Spread, QIntess, Vortex, Indra, and BRB. My work spans Java/Spring Boot, Angular, APIs, enterprise legacy modernization, secure authentication, databases, testing, and production troubleshooting.

Through HVogel, I publish cloud-native Java and AI projects including the HV Fatura/Assinaturas microservices platform, FilePack API, and HV Assistant using RAG, Spring AI, Claude, OpenAI embeddings, PostgreSQL/pgvector, Redis, Docker, AWS, Google Cloud Run, and CI/CD. I also developed HealthIA, a Python/FastAPI ML and NLP API for symptom-based diagnostic support.
