Website with app

I am looking for a skilled freelancer to create an e-commerce website for me, with a mobile app built in React Native and Node JS. The app will use a MongoDB database, as well as Python for programming. I would like an easy to use interface which is attractive, with a strong emphasis on plain-text and data security. The mobile app must include features such as sign in/sign up, search and filter, customer accounts, product page, ratings at checkout, and personalized recommendations.

I require the website to be fully responsive and compatible with all browsers and devices. I would also like the webpage to look professional and be designed in a way to make customers want to purchase my products.Finally, I would like user-friendly navigation, making it easy to browse, find, and purchase my products.
