PHP Laravel Developer Needed to Customize MultiGig - Service Script

I'm looking for a PHP Laravel developer to make a specific customization on my MultiGig - Service script. The current script allows users to choose their preferred language through a dropdown menu at the bottom of the registration form. However, I need to modify the behavior of the script such that the language selection should appear only once and remain fixed throughout the session.

Key requirements:

- Modify the script so that the language choice made during registration is the default setting for the entire session.
