Experienced Java FX programmer needed (only bid if you have experience in JavaFX)

Hi I have an incomplete Java FX project that i need finished ASAP. It is basically a file explorer for Mac OSX (similar to finder) with the usual CRUD operations. I need the following additions: 1. Right now the design is very basic, need someone to finish it based on client requirements 2. Add firebase integration ( not essential, but would prefer if you can do it) 3. Only show recent files from a specific directory and add a counter 4. Right now, user can drag and drop files inside the app, however need you to implement drag and drop feature to created folders to favourites location on the side menu(all inside app). Please only bid if you have experience in JavaFX and know what you are doing. The project is simple but as I am short on time i need someone to finish asap, and not spend time figuring things out. Also prefer if you have a OSX machine. Payment is $30-$50. Of course lower the better. Like mentioned above firebase integration is not essential, but would prefer if you can do it.
