If a potential employer is only going to look at your GPA, then you probably wouldn't want to work such a jerk. Having work experience (I'm assuming the 4 years are full time - not internships) and a MS would make you look pretty good. I don't know about the non-work metrics (GitHub & SO), but certainly continuing to work for the likes of Cisco is going to look good. The only suggestion I would make is to avoid being a jack of all trades. Make sure that your experience is substantial in a small number of in-demand areas.
