I'm Vinícius Estevam, a Senior Software Engineer based in Florianópolis, Brazil.
Currently at Stone (NASDAQ: STNE), one of Brazil's largest payment processors operating in a massive market. I architect high-throughput card payment systems on AWS EKS with TypeScript/Node.js, PostgreSQL, Kafka and SQS.
I also founded Stone's AIOps Chapter, a cross-functional initiative to standardize AI tooling adoption across engineering: workshops, prompt engineering training, and shipping AI-augmented dev workflows that have cut new-provider integration timelines by ~75%.
