Android App developer expert needed (Android Studio)


i have a special android app that we are using in a barcode scanner device in our warehouse. The app was developed in android studio and i have the source code of it. Unfortunately the app has some bugs for example it should upload a csv file to our ftp server but that csv file is always empty. Before this was working fine but then the old developer did some changes and now its not working fine anymore.

So we need your help to check this csv export and fix it so the file will be uploaded fine again to our ftp server. We can send you the app in direct message so you can check it.

We are looking for a skilled android developer as we have many tasks with this app always. We want to improve it and add more functions to it.
