Our production Android app is stable in the market, but I now need a rapid, one-month push to get the entire platform ready for a broader launch .The existing codebase will be shared the moment we agree on the scope, after which I need you to work end-to-end across web services and mobile. Here is what has to happen during the sprint: • Backend upgrades – Refactor database management for speed and reliability – Tighten user authentication flows and token handling – Clean up and extend API interactions so both mobile clients consume a single, consistent layer – Add real-time notifications (push and in-app), advanced analytics collection, and payment processing • Front-end polish on the current Android build – Refresh the user interface design to match new brand guidelines – Improve interactive elements for a smoother, more intuitive experience - need to add few more features in mobile app and web admin portal Acceptance criteria: the revamped backend must pass integration tests, both mobile apps must compile from a single branch, and the final builds have to clear our staged QA before store submission. If you are comfortable moving fast, collaborating via Git and a shared project board, and can commit to daily check-ins for the next four weeks, let’s lock in the timeline and begin.
