Dylan Dechant, Director of Engineering at Illustrative Mathematics, discusses how the non-profit organization utilizes FusionAuth to manage authentication for its K-12 math curriculum content, ensuring teacher-specific materials remain secure. The organization, which aims to make mathematics enjoyable and accessible, especially values FusionAuth for its cost-effectiveness, as it offers a solution at about half the price of alternatives like Auth0. While the U.S. is the primary consumer of their materials, Illustrative Mathematics strategically avoids storing student data to navigate privacy concerns. Dechant highlights that the integration involves custom work, particularly in reporting and user experience, and suggests improvements for FusionAuth's ruby SDK and admin features. The organization relies on FusionAuth Cloud's high availability plan for its operations, and the engineering team focuses on supporting content writers and ensuring the content is accessible, whether through digital platforms or print materials.
