Worked on the uutils/procps repository to migrate process priority management and page size retrieval system calls from libc to Rustix, focusing on enhancing cross-platform compatibility and performance. Leveraged Rust and system programming expertise to preserve the existing API while introducing improved error handling and clearer error reporting. Addressed and resolved Windows build issues that previously hindered deployment, resulting in more stable continuous integration and reduced maintenance overhead. The migration laid the foundation for future Rust-based syscall enhancements, demonstrating a methodical approach to cross-platform development and process management while maintaining API stability and minimizing changes to the overall interface.
