Over a three-month period, contributed to the starkware-libs/stwo-cairo repository by developing and refining core verifier features in Cairo and Rust. Work included unifying cryptographic relation usage tracking across Blake, Pedersen, and Poseidon components, implementing memory address bounds for improved safety, and enhancing code clarity through targeted refactoring. Addressed FRI verifier robustness by adding domain ordering checks and explicit error handling to prevent silent failures. Improved maintainability with consistent naming conventions and clearer documentation, supporting onboarding and long-term code health. Focused on assertion implementation, cryptography, and smart contract logic, consistently delivering features and bug fixes that strengthened verifier reliability and observability.
