LinkedIn and your resume: Critical differences (in my opinion)
Today, as I sleepily scrolled through news articles on Facebook (not a morning routine I recommend, by the way), I noticed this article from Business Insider about words to avoid on your LinkedIn profile. So much of it I agreed with, but the first few words (I, me, my) I actually think SHOULD be part of your LinkedIn page. To me, a formal resume and your LinkedIn profile serve different purposes and therefore shouldn't have the same language.
LinkedIn should represent who you are as a professional but should not be as dry and factual as a resume. Your profile on LinkedIn should help you stay connected with former coworkers, allow you to represent yourself to prospective employers and clients, and also give other professionals a sense of your voice. You cannot do that in the formal language of a resume.
The technique I employed on my own profile was to use personal language in the summary and in my current work then bulleted facts about skills and results throughout the remainder of my professional experience. I did this mostly because my experience in the software industry is no longer as relevant to my current professional goals as it once was. You may wish to include your voice throughout the first several descriptions of roles you've had. In other words, I prefer a format where the most relevant and recent experience on a LinkedIn profile includes personal voice, accomplishments, and skills while less relevant or recent experiences list only skills and results.
