Build me tools of online assessment (MCQs, surveys, etc.)

I need a full stack developer to build 3 tools of online assessment that can be used from the same dashboard. We will embed those tools/assessment systems and they are based on the concepts of doing psychometric tests, surveys and MCQs. Second, the developer has to build an Email-OTP authentication system with an API setting to link authentication of a user account to a wordpress site. Documentation shall be required from the developer at the completion of the project. A Non-Disclosure Agreement shall have to be signed by the developer.
