Worked on the google/heir and opencompl/lean-mlir repositories, focusing on enhancing the ModArith dialect for improved arithmetic representation and maintainability. Refactored operation-related code into dedicated files to streamline future development and updated build configurations for consistency. Delivered CRT-based Residue Number System (RNS) support with decomposition and interpolation, enabling broader compatibility across dialects and verification stages. Addressed compilation failures and improved type readability by introducing human-readable names. Leveraged C++, MLIR, and TableGen to extend compiler infrastructure, applying expertise in code refactoring, IR design, and formal verification to support cryptography-related workloads and ensure robust, maintainable codebases.

Jun 1, 2025June 2025 performance summary for google/heir and opencompl/lean-mlir. Key features delivered include ModArith: Add CRT-based RNS support with decomposition/interpolation in mod_switch, establishing RNS type support across builds, dialects, and verification. Major bugs fixed include SSA.Projects.ModArith.Examples compilation failure and adding human-readable Ty names. The project also completed a Copybara import to align repo standards. Overall impact: broader arithmetic representation, improved build reliability, and clearer diagnostics, enabling faster iteration on cryptography-related workloads and MLIR dialect enhancements. Technologies demonstrated: MLIR dialect extension, RNS/CRT arithmetic, decomposition/interpolation, build/verification integration, and codebase hygiene."
