AWS Cognito User Authentication Set Up

We're looking for an expert in AWS and web development to set up and integrate our user authentication system for EquityBound. This project requires AWS Cognito-based authentication system, with OAuth integration (Google/Apple), for four user types with role-based access control (RBAC). Strong expertise in AWS and authentication systems needed.

Key Responsibilities:
- Finalize registration flow for four distinct user profiles (Standard, Student, Advisors, Friends&Family)
- Complete implementation of role-based permissions
- Set up backend + connect existing login and logout functionality to backend
- Integrate OAuth (Google/Apple) login options
- Integrate with the current system
- Ensure all access controls are secure and functional
- Track progress in our tracker as you progress

Ideal Candidate:
- Full-stack developer with proven AWS Cognito and authentication / user registration / form validation expertise
- Proficient in Next.js, React, AWS, MongoDB
- Familiar with JWT token authentication and RBAC
- Experience implementing OAuth integrations

The registration system needs to follow a minimalistic approach similar to Claude/Airbnb/Netflix:
- Minimal initial fields (email, name, password)
- Quick signup process
- Optional detailed profile completion
- Email verification
- Secure role assignment

If this goes well - the project will lead to additional work on our team.
