Summary
Leonardo Bittencourt is a Tech Lead based in São Paulo with eight-plus years building full-stack JavaScript systems, specializing in Node.js, React and React Native for complex healthcare and fintech products. He has led end-to-end development of patient-facing portals and internal hospital tools at Atria, designed GraphQL federation and BFF layers at Under Armour, and reduced checkout latency and caching costs at PayPal. Comfortable shipping greenfield projects and operating in lean, asynchronous teams, he pairs hands-on coding with architectural thinking and cloud-native pragmatism (AWS, Kubernetes, gRPC). An MBA-trained practitioner in clean architecture and cloud development, he often bridges frontend UX needs with robust backend services and testing discipline—an engineer who moves quickly from prototype to production while keeping systems observable and cost-efficient.
