Full Stack Task Management System with 1.2 s load time and 40 ms TBT

I didn't implement the drag and drop feature because I believe that will make the app less performant because we need to update the database on every drag and drop or every fixed time interval, which will make consistent calls to the database. Is there a way to implement the drag and drop functionality in a performant way or I have to sacrifice performance for some features?

Please check the architecture diagrams I included on my github repository and let me know what you think of the app architecture. Thank you.
