Data Scientist

Superior Beverage Co. Inc.

Montgomery, IL

Embedded data scientist at a regional beverage distributor; operations research, decision-support systems, and KPI infrastructure.

  • Cleaned and normalized legacy ERP data covering package weights, vehicle constraints, and delivery records.
  • Built time-distance matrices via the Google Maps API and ran routing scenarios in OR-Tools and Timefold; time-on-route generalized better than mileage as a cost function.
  • Modeled customer lifetime value across service levels, route economics, and account-level revenue patterns; identified which contractual and operational levers actually moved CLV.
  • Estimated ~25% available time savings on routes at constant delivery frequency, validated in OR-Tools and Timefold; recommended GPS tracking adoption to close the data gap blocking implementation.
  • Built four role-gated KPI dashboards over live ERP data, covering operations, sales team, sales analytics, and company-wide views, with user-driven grouping and aggregation.
