What I'm looking for

I'm looking for remote opportunities where I can own and build distributed fintech, payments, logistics, or applied AI platforms end to end. I'm authorized to work remotely from Brazil with full-day overlap with US and Canada time zones, and I'm open to relocation with sponsorship.

At Rodojunior, I own the architecture and delivery of Vitrum, a core logistics and fintech platform. I designed and maintain a 16-service NestJS monorepo, shared libraries, private registries, and the self-hosted infrastructure that runs the stack.

I build event-driven systems end to end, from PostgreSQL modeling and DDD/Hexagonal architecture to RabbitMQ messaging, transactional outboxes, CI/CD, and observability. I also deliver applied AI in production through RAG pipelines, LLM agents, Claude API, LangChain, MCP, and pgvector.

Previously, I built lending microservices at Banco Pan and enterprise Angular and Node/TypeScript platforms at Tivit. My earlier work at Take Blip and ON GO Company included chatbots, API integrations, React applications, .NET/C#, and scalable database solutions.

I enjoy owning complex platforms from implementation through reliable delivery and infrastructure operations.
