Worked on enhancing the stability and reliability of the headless engine in the projectdiscovery/nuclei repository, focusing on backend development and system programming using Go. Addressed a critical issue where the shutdown process previously terminated all Chrome instances, which disrupted unrelated browser sessions. Introduced a targeted shutdown mechanism by leveraging the launcher Kill() method, ensuring only the browser process initiated by the engine was terminated. This approach improved the startup and shutdown flow, reducing flakiness in automated headless scans and strengthening lifecycle management. The work contributed to more reliable automation workflows and minimized unintended side effects during headless engine operations.
