PROFILE
Simon Žlender
Worked across multiple nixpkgs repositories to improve package management, build reliability, and developer experience. Delivered a feature upgrade for Redocly CLI in raexera/nixpkgs, focusing on reproducible builds and reducing update noise. In GaetanLepage/nixpkgs, addressed C and Rust compatibility issues by patching curlMinimal to prevent resource leaks and updating refinery-cli dependencies for Rust 1.80+ support. Enhanced cross-compilation robustness in tweag/nixpkgs by disabling Linux-PAM audit on non-Linux platforms, and improved NixOS/nix profile upgrades by ensuring tarball cache freshness. Leveraged C, C++, and Nix, with strengths in build system configuration, cross-compilation, and system-level patching for stability.

Aug 1, 2025August 2025: Focused on cross-platform build reliability for tweag/nixpkgs by fixing Linux-PAM cross-compile issues. Implemented a targeted Linux-PAM change to disable audit during cross-compilation on non-Linux platforms to avoid requiring Linux headers and prevent build failures. The fix aligns with our goal of stable, reproducible multi-OS builds and reduces CI noise.
