Looking for someone to replicate android apps and websites. (WhatsApp API, php etc) From my understanding, the website actually its to push the file (XLS, CSV) to the android device, after the device receives the file, it will send the WhatsApp message out one by one.

- Admin will create for user name, password, and device limit.
- Users to log in from the Devices, for example, Samsung S20, will recognize as one device. (Server, user name, password)
- Users to log in from the Website, this is no limitation. - Users to upload the files (xls, csv) and the apps will bulk send the WhatsApp (column 1| column 2) = (contact with country code|Message)=(60122828688|Message A)
- It will show the result in which the messages are sent or failed.

I'll put the screenshot of apps and website, You can refer to the attachment. I can provide the Android APK and website login if you are able to assist with this project. I have my own hosting. Chat with me to understand more on my request. Cheers.
