Experienced Wix Studio Expert for Comprehensive Website Upgrade (Ui/Ux, Cms, Velo)

We are seeking a highly experienced Wix expert to undertake a comprehensive upgrade of our existing Wix Studio website. This project requires immediate availability and must be completed within a maximum of one week.

The current website can be accessed via the temporary link: https://wisemanlove.wixstudio.com/website-5
The registration page is at: https://wisemanlove.wixstudio.com/website-5/registre.

Some pages, specifically "Reseau" and "Login", are nearly complete and will require minimal to no modifications. However, the following key pages require significant upgrades:

- Welcome (Dynamic)
- Meet_Up (Dynamic)
- My Profile (Dynamic)
- openProfil (Dynamic)
- General Posts (Dynamic)
- Team Pages (Dynamic)

Scope of Work:

1. Visual Upgrade (ui/ux): improve and modernize the overall design across mobile, tablet, and desktop devices. The goal is to achieve a clean layout, ensure consistency, and implement a professional social-feed style interface.

2. CMS & Database (Major Part): This is the central component of the project. The successful freelancer must possess a deep understanding of Wix CMS structure, dynamic pages, datasets, data references, permissions management, and member-based content. The work involves optimizing data linking, preventing duplicates, and ensuring a robust and clean database architecture.

3. Wix Velo Development: Refactor and enhance existing Velo code, optimize database queries, correct any logical errors in CMS linking, and establish a scalable code structure.

Important: This is not solely a design task. Strong backend knowledge of Wix CMS and Wix Velo development is absolutely mandatory for this project.

Deadline: The project has a strict deadline of one week. Immediate availability is essential.

Before submitting a proposal, all interested developers MUST visit the provided website links, thoroughly analyze the existing structure, and gain a complete understanding of the project's scope. Proposals that do not demonstrate prior site review will not be considered.

Please include the following in your application:

- Examples of advanced Wix projects you have completed.
- Your proposed technical approach to this upgrade.
- Confirmation that you have reviewed and understood the current website structure.

We are looking for a serious, efficient, and technically proficient Wix professional to join us.
