My Base 44 mobile app is already 90 % complete, and I need a skilled developer to carry it over the finish line. The work that’s left touches three key areas: 1. UI polish • Refine the Login screen, Dashboard, and Settings page so they look consistent and responsive across devices. 2. Backend integration • Wire up the payment gateway, third-party authentication, and database connections, making sure each call returns the correct data and errors are handled gracefully. 3. Bug fixes & testing • Squash any outstanding issues, run end-to-end tests, and deliver a clean build ready for release. I will give you the current source, API docs, and access to the staging server. Once the updated build passes my smoke tests, we can wrap up. If you have recent experience finishing projects of this size and can start right away, let’s talk—there’s only 10 % left to go.

Hi,I carefully reviewed your requirements and understand that your Base44 mobile app is already 90% complete, and you're looking for someone to finalize the remaining work without disrupting the existing functionality. My approach will be to first review the current codebase, identify the pending tasks, and complete them with clean, maintainable code. I'll refine the Login, Dashboard, and Settings screens to ensure a consistent and responsive UI across devices. I'll integrate the payment gateway, third-party authentication, and backend APIs, making sure all requests are handled correctly with proper error handling and reliable database communication. Finally, I'll fix the remaining bugs, perform end-to-end testing, and deliver a stable release-ready build. I have experience working on existing applications, completing unfinished projects, integrating APIs, and improving UI while preserving the current architecture. I'll also provide regular progress updates throughout the development process. Before we begin, could you please let me know which technology Base44 is built with (Flutter, React Native, native iOS/Android, or another framework)? That will help me estimate the implementation accurately. I can start immediately and work efficiently to get your application ready for release.
