During August 2025, Giray Garan developed a dbt model called top_spenders_mtd in the soubhikgorai/ah-datakitchen-dbt-tool-eval repository to identify the month’s top-spending customers. Leveraging SQL and dbt, Giray joined customer and order datasets, aggregated order amounts per customer, and ranked them by total spend to provide actionable insights for business teams. The model was implemented and refined over two commits, with attention to modularity, testability, and clear data lineage. While no bugs were addressed during this period, the work demonstrated solid data modeling skills and delivered a focused feature that supports targeted engagement and revenue analysis for stakeholders.
