Developed comprehensive documentation for real-time notifications using Server-Sent Events (SSE) in the Kernel360/blog repository, focusing on knowledge transfer and onboarding. The work detailed the rationale for choosing SSE over WebSockets for unidirectional data flow, provided an architecture overview, and included practical Java code examples for controller setup, connection management, and notification delivery. By publishing this technical reference in Markdown, the developer created a reusable blueprint to streamline cross-team adoption of real-time features. The documentation emphasized maintainability and clarity, enabling faster implementation and easier onboarding for future contributors, while addressing both the technical and architectural considerations of SSE integration.
