At SauvviTech, I lead a team of 10 engineers building fintech and healthtech products. I led consolidated billing for more than 10,000 installments, helping reduce customer friction, and a contractual and billing model change that delivers BRL 200,000+ in annual savings.
I also led the move from a monolith to event-driven microservices using Kafka, MongoDB, Kubernetes and AWS. The work raised uptime from 99.3% to 99.9% and cut critical-service latency from about 90 ms to about 50 ms.
Earlier at SauvviTech, I redesigned Kafka consumption around a unified model routed by messageType, reducing Confluent Cloud costs by about 40%. I also introduced idempotency, retries and event traceability, contributing to fewer duplicate events and a 99% event success rate.
At Telefônica Brasil (Vivo), I built Automat, a Python and Flask test automation tool adopted for internal technical validations. I also teach backend development at LionsDev, and built Conecta-Bank, an award-winning financial inclusion MVP with Node.js, MongoDB and AWS.
