Hello,
I have considerable experience working with Cordova apps (over 4 years now) and using various different frameworks with it, i.e., Angular, Vue, React, etc. So much so that for a certain client, I created a whole new framework myself. I am more than willing to help you manage, update, fix errors on and maintain your code base, whilst also fixing issues with Javascript that otherwise go overlooked making sure that the mobile app is optimised for the best possible resource usage.
If you consider me for this project, I am sure you will not be disappointed and you will get what you require with the least amount of hassle.
Thanking you in anticipation.
Arun
