Expert Mobile Ui Fixes for Cross-Platform App (Flutter/React Native)

We are seeking an experienced mobile developer to address critical UI misalignment issues within our existing cross-platform application. The app is built using Flutter and React Native and is currently exhibiting layout problems on various Android and iOS devices, including both phones and tablets.

The primary objective of this project is to identify and resolve these user interface inconsistencies to ensure a seamless and responsive experience across all target devices. Specific issues include, but are not limited to, misplaced buttons, incorrect padding and margin applications, and improper font scaling.

Key responsibilities for this role will include:
- Thoroughly testing the current application layout on a range of Android and iOS devices (phones and tablets) to replicate and document all UI discrepancies.
- Precisely identifying the root causes of the UI issues, such as layout constraints, styling conflicts, or responsive design breakpoints.
- Implementing effective CSS/layout fixes or adjusting responsive breakpoints as necessary to correct the misalignments.
- Delivering final builds or providing detailed code snippets for review and integration into our codebase.

The ideal candidate will possess strong expertise in mobile responsive design principles and a proven track record in native platform testing for both Android and iOS environments. Your ability to diagnose and rectify complex UI problems will be crucial to the success of this project.
