E-commerce Site Development: Frontend & Backend Experts

I am looking for a talented front end and a back end developer to create a custom e-commerce solution for me.

Essential Features:
- User Authentication: I need a robust system that allows users to create accounts, log in, and manage their profiles seamlessly.
- Shopping Cart: A reliable shopping cart that can handle multiple items, provide updates on stock levels, and allow for easy modifications is a must.

The project does not require payment gateway integration at this stage, but future collaboration may involve adding this feature. Therefore, experience with secure payment integration would be a plus.

Ideal Skills:
- Proficient in front end and back end development
- Experience with creating custom e-commerce solutions
- Knowledge of implementing user authentication systems
- Expertise in developing shopping cart functionalities

I am looking for professionals who can deliver high-quality work within agreed timelines. Please include examples of your previous work in your bid.
