I'm just putting together a portfolio that lists all the websites I have developed / worked on during the past year.

Now this has become quite a long list - simply because 60% of the websites I have listed are ones where I have developed certain sections of the site, or maybe re-developed a certain section of an existing site - but not actually developed the whole site. So basically you could say I made a 20-50% contribution on those particular sites.

I don't want to give the false impression to a potential employer that I have actually fully developed all the sites listed on my portfolio. Therefore I am after a neat way to indicate this fact.

On the websites that I have fully developed, I have put a small label next to the name which reads "Lead Developer". What would be the equivalent label to put on the sites I have partially developed, or projects where I have been amongst multiple people developing?

I suppose what I'm asking is, how would you define, in 2-3 words a non-lead developer role within a project?
