At GCB Investimentos, I built GCB Hub from scratch using Hexagonal Architecture, DDD, and TDD. It grew to about 100 users, and I digitized client onboarding, cutting the process from days to hours.

At GranaTech, I co-architected the credit approval flow migration and led its frontend, reducing customer wait time by about 60%. I've also delivered investment platform features, ETL/ELT pipelines, and API integrations across wealth management, credit, and capital markets.
