Oussama Kerzazi

I’m an Analytics Engineer and Data Analyst who designs foundational metrics, scalable dashboards, and automated data workflows that executives can trust. Across dealer and financial services environments, I translate cross-functional needs into repeatable reporting infrastructure—built for scale, consistency, and decision speed.

At Mercedes-Benz USA, I lead end-to-end analytics data products, including a Tableau and iPadOS toolkit. I model and standardize financial metrics across 300+ dealerships, and I’ve improved reporting efficiency by 40% while aligning KPI definitions for customer retention, loyalty, and lifetime value across Sales, Finance, and Operations.

Previously at Mercedes-Benz Financial Services, I led cross-organizational program development using internal and competitive market analysis to forecast effectiveness—driving a 15% increase in customer retention with 10,000+ new vehicle sales. I also supported 10+ national marketing campaigns by querying the data warehouse, improving Salesforce CRM suppression logic to increase send rates by 50%, and building automated SQL-based workflows to reduce manual processing by 90% for loyalty eligibility and incentive payments across 300+ dealerships.

I’m particularly focused on automation and traceability: I engineered an automated Python/SQL attribution ETL pipeline linking CRM marketing campaigns to retail sales and reduced manual reporting by 60% through executive dashboards. Earlier, I built Tableau/Power BI dashboards and streamlined ad hoc reporting using IBM Cognos and Experian Velocity, strengthening my ability to deliver actionable analytics with minimal friction for business teams.
