Do you have a system in place for choosing people on LinkedIn to reach out to? I don't know what's a good starting point- seeking in local companies first or with companies that are just related to my developer niche. In job boards I tend to email blast a lot of applications.
And yeah, I haven't really felt part of a team since 2010. Contract jobs can wreck your visibility if you're not skilled in tailoring your connections.
Like I have been told I do great work but they never want to re-engage for more work. Not in six months, not in two or four years.
