PROFILE
Jason Safaiyeh
Worked on stabilizing and improving developer experience in large-scale React Native projects, focusing on monorepo management and native iOS reliability. In vercel/turborepo, addressed onboarding friction by exporting TypeScript configuration files from a shared package, resolving tsconfig.json errors and enabling seamless React Native Web Template initialization across environments. Later, contributed to software-mansion/react-native-screens by fixing a native Objective-C crash related to iOS bottom accessory invalidation, ensuring correct observer management and idempotent KVO setup without altering the public API. Leveraged Objective-C, TypeScript, and React Native expertise to deliver targeted bug fixes that improved cross-platform stability and maintainability in production environments.
