PROFILE

Liam Fisher

Worked on the pq-code-package/mldsa-native repository to enhance cross-platform cryptographic proof infrastructure and improve code reliability. Developed nix-based cross shells and cross-generated bytecode support, enabling HOL-Light builds across x86_64 and aarch64 architectures. Refactored CBMC proofs into a modular configuration, streamlining maintainability and scalability for cryptographic workflows. Introduced a macro in C to enforce return value checks for all value-returning functions, strengthening error handling and reducing silent failures. Leveraged C, Nix, and continuous integration pipelines to automate cross-compilation and testing, resulting in a more robust, architecture-agnostic development environment with improved maintainability and explicit error management throughout the codebase.
