Cover image for Most small businesses are making

Most small businesses are making decisions off numbers they don't fully trust. Mismatched reports. Spreadsheets that take hours to update. Metrics that mean different things to different people. I spent 4 years fixing exactly this at HCA Healthcare across 186 facilities and at Dell across 100+ enterprise accounts. Reduced manual reporting by 60%. Standardized 30+ KPIs so every team was finally working from the same numbers. Now I bring that same rigor to smaller teams that need real analytics without hiring a full-time analyst. If your data is a mess or your reporting takes longer than it should, that's exactly what I do. Open to dashboard builds, SQL audits, and monthly reporting setups.

Cover image for Carrier Optimization Engine, $293K Savings

Carrier Optimization Engine, $293K Savings Model Built a Tableau optimization engine modeling carrier rate scenarios across 28 shipping lanes to identify validated cost-saving opportunities. The analysis found $293,482 in annual savings, an 18.6% cost reduction, and $58.70 potential savings per shipment by comparing current rates, proposed rates, and savings by carrier. The dashboard also surfaced the highest-value optimization lanes, with the South region representing $71K in opportunity and lane-level savings ranging from 18–20% across multiple carriers.
