From a usability perspective you should add more technologies and make the textarea itself bigger. I can appreciate the need to control the terms you are allowed to choose but lets say someone releases a new JS framework tomorrow and it hits major popularity in a month - your site might still not have this. Perhaps this should work as pseudo-tagging. In any case I love the idea since I want to take on part time project gigs apart from my full time job.
