During March 2026, Fedotov focused on backend reliability improvements for the axios/axios repository, addressing a critical issue in HTTP/2 session management. He implemented a targeted fix in JavaScript and Node.js to ensure that detached HTTP/2 sessions are properly closed upon timeout, directly preventing memory leaks and enhancing resource management for long-lived connections. By refining the session lifecycle, his work strengthened the stability of HTTP/2 support for users relying on persistent backend services. The solution was delivered as a stable patch linked to issue #7457, demonstrating a deep understanding of HTTP/2 protocol intricacies and practical backend development challenges.
