Hi,
I have an individual team of Ionic Cordova they having a good experience of more than a 4 year.
Will do your backend in Ionic.
Sure I will provide you full control your application by your Ionic Backend.
We will use NodeJs to develop the Apis and provide you with an App Backend + Apis.
Just list your backend functionalities so that I can give you a time estimation.
I will do that job. Just provide me with your job information on chat. So that my team will understand and start the work.
Thanks,
Webdesky
