During January 2025, Frederic enhanced price data completeness for multi-chain assets in the duneanalytics/spellbook repository by integrating GGP token price data for the Avalanche C-Chain. He extended the existing data model using SQL to store and expose detailed token metadata, including identifiers, blockchain, symbol, contract address, and decimals, enabling more reliable price tracking and downstream analytics. Frederic maintained strong traceability by linking his work to a specific commit and issue, ensuring transparency in the development process. His contribution demonstrated depth in data engineering, focusing on robust data modeling and integration to support cross-chain token pricing and analytics workflows.
