Summary
👤
Senior🎓
Top SchoolLeandro Aparecido is a Staff Software Engineer based in São Paulo with 14 years of professional experience designing and implementing enterprise-grade systems across finance, retail, logistics and port operations. He has driven architecture and implementation work from Java/JEE roots to cloud-native stacks (Spring Boot, Kubernetes, AWS) and has a strong track record modernizing banking platforms and optimizing supply-chain operations to reduce costs at scale. Leandro combines hands-on coding with developer tooling and process improvements—introducing CI/CD, observability and standardized build pipelines across teams. He’s comfortable across the full stack, having led frontend modernization with Angular as well as backend integrations with messaging and relational databases. Less obvious: he often pairs architectural vision with pragmatic cost-saving features (e.g., delivery-route optimization and fulfillment systems) that directly impact unit economics.
