At Claro Brasil, I build end-to-end capabilities for the Minha Claro ecosystem, spanning React Native, Node.js/NestJS BFFs, and React admin tools used by millions of telecom customers. I delivered configurable catalog and secure contracting journeys for more than 80 digital services, alongside roaming, international passport, SIM activation, and cross-product migration flows.
Previously, I led a five-developer team on GOL's critical Check-in domain, helping raise NPS from approximately -2 to above +60. I modernized production modules from JavaScript to TypeScript, introduced progressive quality gates reaching 90% coverage for changed code, and resolved a security-library issue responsible for roughly 300,000 monthly crashes.
Across Neon, Midway, China in Box, and geospatial government platforms, I've delivered financial, onboarding, card, notification, and field-data experiences. I bring hands-on experience in React Native, Node.js, AWS serverless services, GraphQL, native Android/iOS bridges, modular architecture, security remediation, and technical leadership.
