The scalability and performance (speed and overall smoothness of the UI) of the app is very important. Advanced search capabilities is significant as well (and of course security). Database needs to be futureproof, so may be mysql or similar (I am open for ideas on the technology side).
I don't have a design, so if you have eperience in designing that would be great as well.
