May I ask how employers are even finding out about you to give you these "constant" job offers? I've been a solo project guy for a long time and feel like employers are unaware that I even exist.
I'm going to guess your resume has a Google/Amazon/Facebook name brand on it somewhere.
LinkedIn and personal recommendations mostly. I have absolutely no "name brands" on my resume (I stay well away of large companies actually), but have a somewhat productive network I've nurtured over the years, which is where I also get 90% of my freelance projects. I also happen to live in Romania, where there's no way to go hungry if you are an even remotely competent developer or other type of IT professional, because the demand outweighs the supply by a huge margin here. Living in the capital (Bucharest) also helps, since the vast majority of IT companies have their offices here.
