Summary

Senior🎓
Top SchoolRoni Castro is a senior software engineer from Paraná, Brazil with nine years of experience and a six-year track record focused on mobile and web platforms. He specializes in JavaScript/TypeScript ecosystems—shipping React Native apps, React websites, and Node.js/GraphQL backends—while also authoring native modules in Kotlin and Swift for platform-specific needs. Roni has a knack for developer productivity: he built monorepo component libraries, automated repetitive workflows (icon pipelines, deployments, PR checks), and increased test coverage to dramatically reduce bugfix time. His work spans end-to-end delivery from CI/CD and release management to offline-native persistence and dynamic CMS-driven screens for white-label apps. Colleagues rely on him for practical architecture decisions and mentoring; less obvious is his consistent focus on automation that transforms multi-developer friction into repeatable, high-quality shipping.
