Worked on the FlipsideCrypto/flow-models repository to enhance data quality by addressing transaction entry duplication and improving data integrity. Refactored SQL queries to retain only the latest record per transaction entry based on insertion timestamps, ensuring accurate handling of both initial data loads and incremental updates. Applied data engineering and SQL development skills to implement deduplication logic and integrity safeguards, which reduced duplicate records and supported more reliable downstream analytics. Maintained clear version control practices with descriptive commit messages, laying the foundation for more resilient data pipelines and facilitating easier audits. Focused on robust, maintainable solutions for trustworthy business metrics.
