After lot's of thinking and tinkering, I realized that I could showcase things I learned, by explaining the various challenges I had to overcome when working on various projects. Each challenge handled could showcase my ability to pinpoint project pain points, and the way I solved it could showcase my problem solving skills.
Putting these in a time scale, could also help convey the progression of experience over the years. So I would try and build a portfolio/profile page around this concept!
