1. My client was using eZetap POS machine. The NPM package for React Native of eZetap is not updated. In the documentation they have mentioned everything for android but not for React Native. So I have gone through the android documentation and modified the NPM package as per the client's requirement.

2. I have created an application for an EdTech startup. They want to avoid installing the application on an emulator. In React Native there are packages to check emulators but those are not working 100%. During my start-up, I created a function using Java for Android for the same functionality. Using the bridging technology of React Native, I called that method and implemented it on React Native.

3. We know through reverse geocoding we can find the address from latitude and longitude. But for that we have to take a subscription to geocoding API. One of my clients wants this feature but doesn't want to take a subscription. So for IOS, I used free APIhttps://api.bigdatacloud.net/data/reverse-geocode-client. But it is not providing accurate results so for Android I used bridging technology and android.location.Geocoder API to find the accurate addresses.
