Seeking full stack dev to address website bugs

Looking for fullstack dev who can review and address any functionality issues on website.

We know that currently user log ins, new user registration and terms& conditions link is not functioning properly. We did have server issues back in September so this may be a simple fix by resetting code to August 2021.

Specific issues:
1. Existing User Log in not working
2. New user registration/log in not working
3. Password reset email [SendGrid integration]
4. Validation email for new users [Sendgrid integration]
5. Link for Terms&Conditions at User Log in not working properly
6. Confirm that social media links are properly installed and connect to correct accounts

The systems we currently use for system are:
- AWS
- GitHub
- SendGrid
- Custom integration for CryptoAPIs API v1.0
- AWS – EC2, Elastic Beanstalk
- GitHub
- Lavarel
- PHP 7.2

The goal is to restore functionality on front end website and email triggers.
