Designed a mobile first marketplace experience as a Progressive Web App, enabling users to browse, discover, manage, and send campaigns directly from their mobile devices. The experience was designed around the needs of users who needed to manage campaigns while away from their desks, with a strong focus on speed, simplicity, and accessibility. I translated complex marketplace and campaign workflows into a responsive mobile experience that made key actions easy to find and complete on smaller screens. The design also maintained consistency with the broader Sendoso product ecosystem through shared components, interaction patterns, and visual language, creating a familiar experience across web and mobile. This approach allowed users to move between devices without having to relearn the product while giving them greater flexibility to manage their campaigns wherever they were.
