Coordinated with internal AE to develop a POC given desired copy and images. The customer wanted branded content to be displayed in a bold and playful manner. I followed typography and color guidelines based on the customer's website. Used Brandcast for website build-out, and also used Figma, Photoshop, and Adobe to edit digital assets.
