Finn worked on modular arithmetic integration for the Polynomial dialect’s NTT and INTT paths in the google/heir repository, updating fastNTT to use mod_arith operations and aligning types with ModArithType. This C++ and MLIR-based work improved correctness and consistency in polynomial arithmetic, with comprehensive updates to tests and dialect definitions to ensure downstream reliability. In llvm/offload-test-suite, Finn addressed documentation accuracy by correcting a test description for NumberParameters, clarifying validation logic for future contributors. His contributions demonstrated depth in compiler development, low-level optimization, and testing, focusing on maintainability and correctness in both feature development and bug resolution.
