Currently I am working on Justinmind prototype of CRM system and going to test in with users next.
I have not enough time to polish its visual design and not sure in its need.
Will it be ok to put it in such state in resume-portfolio?
I think that provided you make it clear that the focus here wasn’t on visual design and do a great job of documenting your processes and the things that you did focus on, then yes, that is completely appropriate.
I agree with Hawk. If it is not your only project then it would pobably be a great addition to your portfolio. Business owners are more interested in things like conversion rates and measureable success. I have the opposite concern that mine is too visual with no UX based examples yet.
