Meghan focused on data model cleanup within the duneanalytics/spellbook repository, targeting technical debt and improving long-term maintainability. She removed deprecated datasets, such as the labels_hackers_ethereum model, and deleted unused SQL models and their associated YAML schema files, including those for BeraSwap pools and Worldcoin accounts. By consolidating schema definitions and eliminating obsolete components, Meghan reduced the risk of data drift and streamlined future development. Her work leveraged SQL and data modeling expertise, emphasizing code cleanup and database management. These changes improved data quality, enhanced query performance, and prepared the repository for smoother governance and safer, faster iteration in future updates.
