Contributed to the Kernel360/blog repository by delivering two technical guidance posts focused on authentication and messaging integration challenges. Documented the implementation of Google OAuth2 with JWT login in Spring Boot, analyzing security implications such as CSRF with SameSite=None and proposing enhancements like refresh tokens and token blacklisting. Later, addressed a Firebase Cloud Messaging integration issue by clarifying HTTP/1.1 versus HTTP/2 behavior in the Java SDK, identifying the root cause of protocol incompatibility and providing a practical workaround. Work emphasized disciplined technical writing, security analysis, and actionable documentation, supporting future development and reducing debugging time for Java-based backend systems.
