During May 2026, Zerray focused on backend reliability improvements for the decolua/9router repository, addressing a potential memory leak in the real-time streaming pipeline built with Node.js and JavaScript. He implemented a robust cleanup mechanism for Server-Sent Events (SSE) listeners, ensuring that event listeners and intervals were properly disposed of when clients disconnected from the console-logs stream. This technical approach protected long-running sessions from performance degradation and reduced operational risk in the logging infrastructure. Although no new features were shipped, Zerray’s work enhanced the stability, scalability, and maintainability of the API-driven backend, demonstrating depth in backend development.
