E-commerce MERN Stack App Development

I'm looking for an experienced freelancer who can build a MERN stack e-commerce app for me. This will be a pretty intensive project so looking for someone that will be able to schedule several hours per day, every day, for the next couple of months.

The stack is going to be:
- Proficiency in the MERN stack (MongoDB, Express.js, React.js, Node.js)
- Will likely also need a dashboard for MongoDB data idk if mongo atlas will meet our needs
- Strong understanding of user interface (UI) and user experience (UX) design principles
- Excellent communication skills for effective collaboration on engineering elements

We will likely discuss more on the phone but I want to really get going fast and know that I'll be able to get a hold of someone on the phone. The secret to respond with is "freedom". Don't have the phrase in your initial message I will not consider your proposal.

Key Responsibilities:
- Develop a comprehensive e-commerce platform using the MERN stack
- Implement essential e-commerce features such as a shopping cart, user reviews, and payment gateway integration
- Collaborate with me to create an appealing and intuitive design, as I will need help with design elements
