Liam Fisher enhanced the pq-code-package/mldsa-native repository by building cross-platform cryptographic proof infrastructure and improving code robustness. He implemented nix-based cross shells and bytecode generation to enable HOL-Light builds across x86_64 and aarch64 architectures, streamlining CI workflows and reducing manual intervention. Refactoring CBMC proofs into a modular configuration improved maintainability and scalability for cryptographic development. In C, he introduced a macro enforcing return value checks, strengthening error handling and reducing silent failures throughout the codebase. Liam’s work demonstrated depth in cross-compilation, DevOps, and software testing, resulting in a more reliable, maintainable, and architecture-agnostic development environment.
