Worked on the srid/nixpkgs repository to enhance pest-ide-tools by removing its OpenSSL dependency and migrating to rustls, thereby reducing external dependencies and improving security. Focused on build systems and package management using Nix, the work also included refining licensing metadata to retain only the Apache-2.0 license, ensuring clearer compliance and simplifying the legal landscape. Build validation and compatibility checks were performed to confirm stability after these changes. This targeted update streamlined the dependency graph, improved maintainability, and contributed to a more auditable toolchain, reflecting a methodical approach to both security and licensing within the nixpkgs workflow.
