Full Stack Developer - With Wordpress Website Experience

I am looking for a full-stack developer for my upcoming product, person should have the ability to handle complex work and codes
it can be a custom code website or also can make in WordPress and add those features, but it should be very safe, load very last, and should be responsive
I can give you an idea, the website will be like a combination of 1mg.com, webmd.com, and practo.com where people can search for their health-related issues, find medicine or product online, and also can book a consultation
