At Definian, I delivered business intelligence reporting for finance, sales, and operations leaders, translating requirements into reporting on Snowflake, SAP S/4HANA ERP, and CRM data. I designed 14 Power BI dashboards with reusable DAX measures, replacing 23 manual Excel reports in monthly business reviews.
I investigated a recurring revenue variance between dashboards and the ERP ledger, then built automated SQL reconciliation checks that reduced it below 0.3%. I also developed governed Snowflake reporting for Power BI and Tableau self-service analytics, helping reduce ad hoc requests.
At Definian, I automated month-end reporting with Python scripts and optimized SQL queries, reducing the reporting cycle from 3 days to 5 hours. I used Microsoft Copilot to draft DAX and SQL, manually validated the drafts, and trained three junior analysts in that workflow.
At StartupBlink, I built a Python ETL workflow to consolidate 10 data sources and rebuilt weekly stakeholder reports using Advanced Excel. I also conducted an A/B test on a newsletter and created Tableau dashboards for comparing city and year funding trends.
