Worked on the werf/werf repository to deliver a security enhancement for file import processes, focusing on preserving security-related extended attributes. Leveraged Go to implement Secure File Import with Extended Attributes by enabling rsync’s --xattrs option, ensuring that security attributes are maintained throughout the import pipeline. Addressed a related bug to consistently preserve security capabilities across build, stapel, and import components, directly improving data integrity and compliance readiness in production environments. Demonstrated backend development expertise and a strong understanding of file transfer protocols and security management, with changes that are maintainable and clearly traceable to specific commits and issues.
