Message

At ONEBRAIN, where I’m allocated to Voll, I develop backend services for critical distributed systems and implement event-driven flows with Apache Kafka. I also contribute to architectural decisions around idempotency and work on data consistency, resilience, and Flutter applications.

Previously at IGMA, I developed systems with NestJS, TypeScript, React.js, and React Native, including an administrative CMS for Mercado Livre Arena Pacaembu. At DISPARO PRO, I developed high-scale microservices and worked on asynchronous processing with Google Cloud Pub/Sub.
