Improvements to the site on laravel

Good afternoon
There is a website on laravel for which improvements and bugfixes are needed.
Examples of tasks:
- User notification settings
- Fix session time so that the user does not log out every day
- Edits to the search functionality
- Editing the layout for mobile devices (not necessary, but if in addition to the back you can do a little more front - this will be a plus)
Communication via tg. Long-term cooperation. Please immediately indicate the rate per hour in the response. Please do not disturb the agencies.
