Senior🎓
Top SchoolLeonardo Santana is a Software Developer from São Paulo with 8 years of experience building backend systems for large enterprises and marketplaces. He specializes in Java and Node.js (TypeScript), designing microservices, asynchronous flows with Kafka/EventHub, and robust APIs backed by PostgreSQL, MongoDB and Redis while applying clean architecture and thorough testing. Experienced across Azure and AWS clouds, he emphasizes observability (New Relic, Grafana, DataDog) and CI pipelines with SonarQube, and has delivered feature-flagged rollouts and serverless components. He has repeatedly migrated legacy batch systems to scalable asynchronous architectures and led teams on critical onboarding flows and high-coverage testing efforts.

A curious full‑stack practitioner, he’s learning React/React Native to complement his backend expertise.
