Refine the micro-site builder on Laravel / Laravel Blade

There is an unfinished micro-site builder (such as taplink.ru) made on Laravel / Laravel Blade and which in principle works, but it needs to be finished.

The constructor itself is not complicated:
- drag&drop interface
- several types of blocks (link, text, title, contacts, social networks)
- A dozen website templates
- presentation of user sites

The main task is to bring the service to the "production" quality:
- review of the current code (what we leave, what we redo/ throw away)
- optimize (database, requests, storage, presentation of sites, cache etc.)
- clean up all current bugs
- bring to the ideal all possible scenarios (onboarding, login through social networks simple login, verification of emails, actions in the personal account, etc.)
- Emphasis on excellent UI/UX (add/fix callbacks, remove unnecessary page reloads, etc.)
- finish everything to the end

In the response, please provide examples of similar works. I will provide a completely ready-made design for desktop / mobile phones in figma and clear TK.

Studios, teams do not intereuse - I am looking for a full-stack freelancer who will quickly bring everything to mind.
