Description: The current codebase is outdated and needs to be updated to ensure compatibility with the latest technologies and security standards. I will recheck the codebase and make the necessary changes along with mentor. This will include:

1. Update all dependencies and packages to the latest versions
2. Check for any security vulnerabilities and fix them
3. Refactor any deprecated code
4. Remove any unused code
5. Improve code readability and maintainability

Tasks:

• [ ] Recheck the codebase to identify outdated packages and dependencies
• [ ] Update all packages and dependencies to the latest versions
• [ ] Check for any security vulnerabilities and fix them
• [ ] Refactor any deprecated code
• [ ] Remove any unused code
