Feedback App with React, Node and PostgresSQL

What are you most proud of, and what would you do differently next time?

I wanted to learn how relational databases work in real world apps, so I was able to design an ER Diagram and convert it to a working fullstack application with Authentication and clean UI. The DB uses concepts like Normalization for handling upvotes, Denormalization for maintaining counts and composite unique key for maintaining uniqueness in upvotes.

What challenges did you encounter, and how did you overcome them?

Managing the entire workflow from DB to frontend can get very complex very quickly. Managing a project with so many moving parts is both fun and challenging.

What specific areas of your project would you like help with?

If someone can tell me how to add Drag and Drop to the Roadmap and make it work with DB, that would be cool. Its the most complex feature that can be added to this app.
