React Developer Needed ASAP – Fix Persistent Screen Jumping Bug in Base44 App

URGENT — Experienced React Developer Needed to Fix RYDER Garage AI I own RYDER Garage AI, a motorcycle repair and diagnostic application built with Base44 and React. The project source code is stored on GitHub. We have a persistent problem where the application unexpectedly jumps or scrolls back to the top of the screen during use and navigation. Multiple attempts to fix this issue have failed. I need an experienced developer who can identify the actual root cause and permanently resolve the problem. Required work: 1. Inspect the existing React application and navigation code. 2. Reproduce the screen-jumping issue. 3. Investigate routing, scroll restoration, component remounting, state updates, and other potential causes. 4. Fix the underlying problem without breaking existing functionality. 5. Test the affected screens, navigation, and scrolling behavior. 6. Provide evidence that the fix works and explain exactly what caused the problem. The application includes motorcycle diagnostics, repair guidance, maintenance tracking, motorcycle profiles, and service history. These features must be preserved. Important conditions: - Work on a separate GitHub branch. - Do not rebuild the application. - Do not delete or disable existing features. - Do not modify production data. - Do not merge, deploy, or publish without my approval. - Provide repeatable testing evidence before the work is considered complete. Budget: $100 fixed price as an initial target, negotiable depending on the diagnosis and scope. Timeline: As soon as possible. Please explain your experience fixing difficult React scrolling and navigation bugs, your earliest availability, and whether you can work with Base44-generated applications. I am looking for someone who can diagnose and solve the actual problem, not apply another temporary workaround.Additional Work — Separate Quote Requested After resolving the screen-jumping issue, I would also like an assessment of several other areas of RYDER Garage AI: - Login, registration, and authentication problems. - Service History PDF generation and downloading. - Motorcycle diagnostic navigation and preservation of user progress. - Error handling and failed loading operations. - Compatibility between the GitHub repository and the current Base44 application. - Critical bugs that could interfere with the upcoming Google Play release. Please identify any confirmed problems and provide a separate fixed-price estimate for repairing them. The initial $100 budget is intended for the screen-jumping repair only. Do not perform additional billable work without my approval. All existing motorcycle data, diagnostic features, service records, and application functionality must be preserved. Do not change live data, merge code, deploy, or publish without permission. I would like a written explanation of the root cause, the changes made, and the testing results for each completed repair.
