I am trying to specialize more in graphics, though I still have to figure out how large is my skills gap between "doing solo graphics projects" and "full-time graphics programmer", especially in math. After getting advice on my resume on how to hide the slow career growth, I've been told to spin it to show I am interested in this niche and show direction towards that. If you had been able to read my un-revised resume, it would probably read like a story that feels the same in the beginning as it is in the end, with no clear conclusion. So I am working on a new version with a different spin.
