Chris worked on improving the stability and reliability of the headless engine in the projectdiscovery/nuclei repository, focusing on backend development and system programming using Go. He addressed a critical issue where the shutdown process for headless scans would inadvertently terminate unrelated Chrome instances. By replacing broad process enumeration with a targeted launcher Kill() method, Chris ensured that only the browser process initiated by the engine was affected, preserving other user sessions. This change enhanced the startup and shutdown flow, reducing flakiness in automated scans and strengthening lifecycle management. The work demonstrated careful attention to process isolation and automation reliability.
