tabrez-rabbani/DevBoard-MERN-Practice ? reverse-engineered prompt

Build me a simple DevBoard app for tracking developer tasks and notes, like a small internal dashboard where I can see what I’m working on, add new items, edit them, and mark them done.

I want it to feel clean and easy to use, with a main board view, a way to create and update cards, and basic navigation that makes sense on desktop and mobile. If it needs a backend and database, set that up too, and make sure the app can save data properly instead of losing it on refresh.

Please wire up the full app so it runs from the existing project, and organize it in a way that is easy to keep building on later. Use current best practices, and look up current docs online if you need to. If anything important is missing, make sensible choices and keep it simple.
