Development of Platform with Enhanced Security

I'm going to make a platform that accepts cryptocurrency payments. This platform is where clients are looking for suitable developers to develop their projects. I had a developer, but the deadline was too long, so I'm looking for a great developer. My shopping site is very great, but I think it has weak security. The developer I am looking for must have sufficient experience and skills in security, Web3, and MERN Stack. It should be resolved as follows: First, users need to complete the signup process using users wallet address, but clicking the "Log In" button now doesn't allow me to sign up on the site. Second, You should design project dashboard with modern and clear function. Third, we need to design for all categories and add new fields and categories. I have a wonderful dream that my new site will do well. and that's why I'm expanding my business. If the new site succeeds, I think we can continue to work together in the future.
