My Cordova-based Android recharge app needs a quick but thorough tune-up. Frontend work • Layout elements should scale automatically across screen sizes and densities, yet they currently stay fixed and break on smaller phones and tablets. • Dark mode is half-implemented—the colours remain in their light-theme palette, leaving buttons and backgrounds mismatched. Backend work Both the distributor and master distributor accounts must be able to create and manage their own downline. At the moment that privilege is missing, so no new agents can be added from the app. Acceptance criteria 1. Layout auto-sizes correctly in portrait and landscape on at least three common Android resolutions. 2. Dark mode switches all declared colours (text, backgrounds, icons) in line with Material guidelines, with zero hard-coded light colours visible. 3. Distributor and master distributor dashboards include an “Add Downline” flow that stores, retrieves, and displays data flawlessly. The project is Cordova/JavaScript on the mobile side; backend is already live, so you will extend existing endpoints rather than rebuild. Please keep naming conventions intact and push changes through Git so I can test on TestFlight builds before sign-off.
