Seems the concensus is that front end is the most imperative thing out of the gate. Seems true in my non hackathon side project, of which I'm the solo dev. Can anyone please recommend a good front end framework/tool for a backend dev? I've been working on a project for awhile and the sequence has been: 1. Get requirements 2. Make excellent back end (and clarify functionality, edge cases along the way) 3. Build non sexy front end that works functionally 4. Get complaints front end is not sexy even though it can do very sexy things through the back end 5. Requirements change massively and now I have to tear down and repeat 1-4 with ever-increasing comments about it not being sexy. Right now everything is django templates + bootstrap + javascript/jquery. It works but is not sexy.
