Evolution of Grammarly's Platform: From Developer Operations to Developer Experience

In this talk, Serhii shares the journey of Grammarly's platform transformation. It all began with a "you build it, you run it" culture that required developers to be software engineers and operations experts. While empowering, this approach created a significant cognitive load and slowed the onboarding of new team members. Grammarly has since significantly evolved its platform to boost developers’ productivity and improve their experience. The evolution of the platform can be traced through several key stages: - Initial Platform Team Intervention: Segregated environments with self-service provisioning and other automation were introduced, though new developers still needed up to a month to become productive. - Platform University: Creation of structured online training courses, reducing onboarding time to one week. - Golden State and Golden Path: Implementing high-level abstractions like one-button service deployments, simplifying complex operations. - Current Infrastructure Abstraction: Moving away from "you build it, you run it" to specialized Infrastructure teams and a whole new tech platform. Looking ahead, Serhii explores how the platform might continue to evolve, incorporating AI-assisted operations, enhanced developer experience features, and a more robust internal platform ecosystem.
