Throughout my time at Woobox, I found myself needing to create some graphics, whether it be for a demo with a client, presentations, one-sheets, social media icons, or support documentation, but I was never asked to do anything officially, at least until pretty late in the game. If I recall correctly, I created a couple graphics at the request of the CEO for some ads, and apparently he was quite shocked with my design chops, as it were.
After that, I was generally the one tasked (officially, this time) with creating any/all graphics when needed. These requests were usually related to featured images in blog posts, Facebook advertisements, or nice images to be used by our sales people for promotions they showed in client demos, but also included creating app icons and general ads to be used across the web.
In addition to creating images, I created templates for all the documents that our team may have needed (be it for sales, support, or otherwise). This work was all done in Google Docs, as that was our chosen word processing system.
