I’m a backend-leaning fullstack engineer based in Rio de Janeiro, with seven years split across media, logistics, and data-intensive systems.
That means data modeling and API design as the foundation, event-driven architecture to connect the pieces, and enough infra know-how — container orchestration, CI/CD, IaC — to actually own what I build end to end. I’ve used that combination to replace a six-figure external contract with an in-house platform in three months, and separately to turn a manual editorial process into an automated one feeding directly off structured data. Different domains, same underlying skill set applied twice.
I have a BSc in Computer Science from Fluminense Federal University (UFF), and lately I’ve been going deeper into AI-applied system design — RAG pipelines, LLM integration, semantic search — applying it in real projects. I’ve also been working a lot with Google products lately, like GCP and BigQuery, Pub/Sub, among others, plus development in Python, Java and Go.
Happy to talk more about any of this.
