During November 2024, SandaruKasa contributed to the srid/nixpkgs repository by refactoring pest-ide-tools to enhance security and licensing compliance. The work involved replacing the OpenSSL dependency with rustls, thereby reducing external dependencies and improving the security posture of the build system. SandaruKasa also streamlined licensing metadata, retaining only the Apache-2.0 license and removing the MIT license to ensure clarity and compliance. Using Nix and leveraging expertise in build systems and package management, SandaruKasa validated build stability and compatibility after these changes, resulting in a more maintainable and auditable toolchain for the nixpkgs workflow.
