Who here has an e-learning portfolio?

For anyone who isn't allowed to share projects that they created for clients, I would recommend trying to create meaningful alternatives that target the industries or clients you want to attract.

For example, most of the portfolio that Shahidyakoob​ and I have created is aimed at the medical, healthcare and pharmaceutical sectors, as that is where most of our work comes from.

Having examples that are relevant to clients that we want to work with means that when they look at our work, they can see straight away what we would do with their content. It removes one layer of risk for them as we've already demonstrated an understanding of their industry. 

If you're a developer but you don't have any instructional design skills, try collaborating with an ID who doesn't use Storyline. You'll both come away much more structured demos that you can share with potential clients than you would if you were halted by your potential limitations. 

If you work in Rise and Storyline, build an example using each tool so you can demonstrate your abilities in both.
