Looking for an Ionic 4, Firebase App expert

I need you to complete the app. The app is almost completed. Some function is not working properly. Admin panel and App needs to be fixed some problems. Currently, my budget is 100$ fixed, but if your work is good, will leave you the good bonus(100+). It may require the website as well after done the app. I will start with 100$ first, but after done, after we checked, before you send me the source code, you will get the more budget.(100+) Will share it on chat.. Thanks.
