Worked on the ethereum-optimism/superchain-ops repository to address a critical bug in Safe wallet validation and streamline the continuous integration process. Focused on updating the message hash and nonce values to accommodate an additional SAFE wallet owner for the 012-opcm-update-prestate-v300-uni task on Sepolia, ensuring accurate validation and improved workflow reliability. Simplified the CI pipeline by removing a deprecated simulation task from the CircleCI configuration, reducing potential flakiness and maintenance overhead. Utilized skills in configuration management, DevOps, and smart contracts, working primarily with YAML and TOML to update CI and wallet configuration files for enhanced test stability and maintainability.
