I served as the marketing director for a small startup company-- I was tasked with creating the designs for their trade show handouts, info materials, banners and custom artwork, client demonstration powerpoints, and an ebook manual for their mobile app.
To create these designs, I used Adobe Photoshop for text design, layout, and image manipulation, Canva for design layout, Adobe Illustrator to create custom vector images and graphics, ProCreate to draw custom artwork by hand, and Canva to create the ebook. 
I also created a product demo video (view on video page).
Example marketing newsletter for client - I used Adobe Photoshop for the product designs and mockups, and the newsletter layout. I drew the logo design in procreate, and designed the custom wallpaper & product designs in photoshop for the mock client.
