Yes, it is true, I handled the entire tech stack for a company with 2000+ insurance agents. I single-handedly did all the networking, pc troubleshooting, wordpress installs/design, sugarCRM integrations, ppc ads, seo, content writing, etc..
But your opinion is, of course, yours. I would suggest being more specific on these jobs either way, so that people like me will not be scared off on their first read of the job titles.
