Worked on the LLNL/serac repository, focusing on enhancing the clarity and extensibility of its physics modules over a two-month period. Addressed a documentation inconsistency by updating the Material Model Stress Type to accurately reflect that functions return the first Piola stress, improving API usability and reducing onboarding friction. Developed foundational changes in C++ to support customizable parameter behavior by making setParameter overrideable in base physics classes, enabling derived modules to tailor parameter management. Prepared scaffolding in residual.hpp for future residual physics features. Applied skills in C++ development, code refactoring, and object-oriented programming to improve maintainability and future extensibility.
