Teespring, a platform that helps customers create and sell products online, has successfully migrated its Ruby on Rails monolith to a Jamstack architecture using an incremental and hybrid strategy. The company's director of engineering, Rick Takes, will share the details of this journey, including the approach to prototyping Jamstack solutions for new initiatives, the challenges encountered, and the results of the migration, which include reduced build times, improved site performance, and conversion rates. Teespring has adopted a hybrid microservices architecture, keeping its data in the Rails application and building smaller microservices with a focus on management and discoverability. The company plans to continue improving performance and developer experience using Next.js on Netlify.
