Update my existing app in Firebase

I am looking for an experienced Freelancer to help update an existing Android app I currently have in Firebase. Specifically, I need a Freelancer to assist me with bug fixes. I already have a list of the bugs that need fixing which includes problems with the app's performance, functionality, and user experience. Therefore, I am looking for someone who understands the importance of delivering quality work and is knowledgeable about Firebase and app development. Must have experience with app development, specifically for Android. If you have the skillset and are up for the challenge, please submit a proposal. Thank you for your time and consideration. Here's the task: 1. have other receipts included and be recognized (reference number, amount, date of the transaction) 2. Have an Edit option beside the reference and the amount just in case the scan got it wrong 3. enable biometrics for login 4. have a other ways to search the transaction such as by amount, by the first 4 digit of the reference it would filter the receipt matches in the query 5. also when you do a search in the history and then you switch the receipt to orig receipt it would load everything and you have to scroll again to the one you want to search, make it remember where you stop, so when you switch the receipt to orig the user doesn't have to re-scroll everything 6. In App Purchase (for subscription) 7. publish the app
