Worked on backend enhancements and documentation improvements across projectdiscovery/katana and projectdiscovery/nuclei-templates. Delivered Chrome WebSocket session reuse in katana by prioritizing the -cwu flag over -headless, enabling authenticated crawling against existing browser sessions without launching new instances. Addressed flag conflict handling with user-facing warnings and maintained backward compatibility, updating Go code in runner.go and options.go. In nuclei-templates, fixed a documentation bug by correcting the cPanel backup exclusion reference URL and aligning guidance with current documentation. Demonstrated skills in Go, YAML, and configuration management, focusing on targeted, maintainable changes that improved reliability, user experience, and repository hygiene.
