Sample Answer
Problem: I received three inconsistent exports (Excel, Salesforce CRM, and an internal Postgres tool) to build a monthly performance report for ~10K customer accounts. Solution: First, I profiled each dataset in Python (Pandas) and SQL: row counts, null rates, duplicate keys, and date ranges. I standardized keys (account_id, month) and dimensions (UTC dates, ISO country codes) and created a mapping table for mismatched IDs. Using a staging schema in Snowflake, I built transformation views to de-duplicate, join, and aggregate, logging all assumptions. I reconciled totals vs. system-of-record (Salesforce) within ±0.5% for revenue and ±1% for activity counts, investigating any variance above thresholds. Finally, I spot-checked 20 high-value accounts with Sales and created a data-quality summary for leadership. Impact: Delivered a trusted report in 2 days, later automated via dbt and scheduled Power BI dashboards, saving ~6 hours/month.
