Cross Platform App - Lastly I worked on their react-native app, which didn't have even 50% of the features compared to the website and mobile website. The first thing I worked on was to bring it to feature parity with the desktop and mobile website. Later on, I implemented a lot of app-specific screens and features. The biggest task was to upgrade the app to newer react-native versions. I upgraded the app twice, Once from v0.63 to 0.67, and another from v0.67 to v0.72. Managed two people under me later on while working on this app.
