Ask HN: Freelance devs, how do you format your LinkedIn profile?

I have a small dev consulting shop I run. Sometimes I work on projects that last six months, sometimes only six weeks. How do other developers working freelance or running small shops format linkedin? Do you list all the major companies you've worked on projects for or include "clients such as" under your main title?

As some more background, I'm fairly young and want to come across as more established. I've worked on some significant projects, but at the same time I don't want to give off the impression that I've jumped around between a bunch of companies.

Solutions?
