Curiosity Stream is a US media company and subscription video streaming service with over 20 million subscribers worldwide. As a UX/UI intern, I participated in a team effort alongside two software engineering interns and two data science interns, with the aim of revamping the company's metadata management system. Our objective was to enhance the experience for content managers in entering metadata and to improve the overall quality of the metadata itself. My specific focus was on improving the tagging experience for documentaries, including features such as automated tagging suggestions based on existing tags, a tagging effectiveness bar to provide insight into the quality of tagging at each stage, and measures to avoid the creation of duplicative tags with similar semantic meaning. Additionally, I designed and developed the company's light-mode UI components from the ground up, ensuring a cohesive and consistent design that aligned with the company's branding.
