https://play.google.com/store/apps/details?id=com.healthed&hl=en&gl=USA React Native-based cross-platform application to provide popular seminars, events, audio, and video materials for Australian GPs. I worked on the existing project using the old React Native version (0.61) with classes and other libraries. It was crashing on the latest Android and iOS devices, so I upgraded React Native and all other incompatible libraries to fix crashes and critical bugs to improve the UX. I fixed all the bugs reported on Apple and Google Store reviews, specifically audio and video player issues.
I also improved the monitoring side of the mobile app by integrating Google Analytics for usage tracking, Sentry for monitoring issues and crashes, CodePush for deploying over-the-air (OTA) updates, and Firebase for push notifications.

Auth0 Guardian Library For React Native
https://www.npmjs.com/package/react-native-auth0-guardianIn one of the projects I was working on, I had to integrate Auth0 Guardian into a React Native project to support multi-factor authentication (MFA).
Auth0 was not supporting React Native, so I had to build a React Native bridge between Auth0 Guardian Java and Swift libraries. I created this library from scratch and open-sourced it. It helped some folks looking for solutions in the React Native community.
