Worked on the ethereum/consensus-specs repository to develop deadline calculation utilities that streamline Ethereum consensus timing. Focused on building reusable Python helper functions to centralize slot time deadline logic, these utilities—such as get_view_freeze_cutoff_ms and get_inclusion_list_submission_due_ms—abstracted time-based decisions across multiple forks. By updating existing handlers to adopt these new helpers, the work improved both the reliability and readability of consensus code. Leveraging skills in blockchain development, Ethereum, and smart contracts, the developer ensured that deadline calculations are consistent and maintainable, addressing the need for unified timing logic within the consensus specifications without introducing new bugs during the process.
