Atakan Eser, co-founder and CTO of Circleboom, discusses how his team utilizes FusionAuth to enhance their authentication solutions, transitioning from relying solely on Twitter's OAuth to a more robust system with FusionAuth's single sign-on capabilities. Circleboom, a tech company focused on improving social media engagement through user-friendly applications, offers two main products: Circleboom Twitter Management Tool and Circleboom Publish Tool, which support multiple social media platforms. With a small team, Atakan oversees all technical aspects, and the integration of FusionAuth has significantly reduced development time and costs, replacing IdentityServer4, Auth0, and Firebase, which did not meet their needs. Despite some usability challenges in FusionAuth’s interface, such as hidden features and non-standard UX, Atakan appreciates its power and ease of use, having implemented it through Docker and Caddy as a reverse proxy for their authentication needs across various platforms.
