Fix existing e-commerce website

We have an existing e-commerce website built using the MERN stack that requires significant updates and improvements. The platform is outdated, and we are looking to modernize both the frontend and backend to enhance performance, usability, and overall user experience.

We are seeking a senior full-stack developer with strong expertise in:

* Frontend development (React, UI/UX improvements)

* API integration and optimization
* Data analysis and handling

The ideal candidate should be able to:

* Redesign and improve the current interface
* Refactor and optimize existing code
* Integrate and enhance APIs
* Work with data efficiently to support business needs

Please include examples of similar projects you have worked on, particularly e-commerce platforms or MERN-based applications.

Further project details will be shared during the interview.
