Native Android Application, Desktop Application (vue.js, electron.js) and Firebase Backend project fixes + features

Hello everyone, I have a project which is essentially, a mobile application on android. The mobile application exists. We have alot of bug fixes that needs to be patched, with features that needed to be added asap. There are 3 portions for this, the desktop apps are in java script, mobile app is java android, and the back-end is firebase. Please note that the desktop app is hybrid with vue.js and electron.js. The android app is native however. Would anyone be able to help me?
