Jewelry Market App – Ui Bug Fixes & Gold Price Logic Correction

We are seeking an experienced mobile app developer to address critical ui/ux bugs and refine the pricing logic within our existing jewelry market mobile application. The app is currently functional, but requires significant improvements to align with our desired user experience and business rules, particularly concerning gold price calculations.

Project Scope:

1.  Ui/ux enhancements for icons, thumbnails, and navigation:
    *  adjust icon sizes and types to ensure visual consistency throughout the application.
    *  Reduce the size of product thumbnails and ensure they do not overlap navigation arrows.
    *  Ideally, replace existing thumbnails with neutral gray circles for a cleaner interface.

2.  Correction of Navigation Arrows Behavior in Product Details:
    *  Currently, the navigation arrows on the product detail screen cycle through images of a single jewel.
    *  The required behavior is for these navigation arrows to switch between different jewelry products, allowing users to browse various items without being confined to a single product's image gallery.

3.  Refinement of Image Size and Scroll Behavior:
    *  Upon opening the details of a jewel, the main image should maintain its size or appear larger, never smaller than its initial display.
    *  When scrolling up to view additional jewel information, the screen content should move naturally upward without compressing or resizing the main image.
    *  Navigation buttons must remain fixed on the screen and should only facilitate movement between photos of the currently viewed jewel, not switch to other products.
    *  If thumbnails are replaced with gray circles, this design choice should be consistently applied.

4.  Accurate Gold Price Calculation:
    *  Implement precise and reliable logic for calculating gold prices based on current market data and business rules.

We are looking for a developer who can deliver clean, maintainable code and ensure a seamless, intuitive user experience. Clear reference behaviors and example images will be provided to guide the development process.
