I am looking someone updating my android app and fix bugs

I am looking for someone to update my Android app and fix bugs. Specifically, I need performance enhancements for my app. I have a comprehensive list of known bugs that need to be addressed. The updates and bug fixes need to be completed within a reasonable timeframe. 1. We need to address the map issue, as users are currently experiencing difficulties with manual location submissions, similar to the process on Foodpanda. Both the user app and the delivery app are encountering problems with the map functionality. 2. We must resolve the OTP issue associated with a popular Bangladeshi SIM company. Despite its widespread use, a significant number of users have reported difficulties with verification. Alternatively, we can explore the option of integrating a third-party OTP service, as the current cost of 26 cents (30tk) per customer OTP is deemed excessive. 3. It is necessary to include text for the registration referral box, making it optional. Users without a referral code can choose to skip this step. 4. We need to modify the subscription boxes, implementing limitations and a required dish selection system. For instance, with packages priced at 120tk, 70tk, and 80tk, users should be allowed to select the 120tk package only once, on a predetermined day such as Friday. The 70tk package requires a minimum selection of 2 days, while the 80tk package covers the remaining days. 5. The automated generated invoice needs improvement, specifically in displaying information such as "Paid," "Cash on Delivery," and the due amount. This information should be visible in the mobile view, considering the use of a thermal printer. 6. We should eliminate the OTP system from the Kitchen and Delivery functionalities, enabling delivery personnel to accept orders without OTP verification. 7. Integration of Nagad and Rocket payment gateways is required. 8. Language-related issues, including spelling mistakes in the text, need to be addressed. Additionally, efforts should be made to enhance the availability of Bangla language options, as many customers find the current language settings challenging. 9. A restriction should be added to the subscription model, preventing users from placing orders with the cash-on-delivery payment option. And any minor bugs we can pinpoint must be addressed and resolved promptly.
