Case Studies

The Proof

Each project is structured using the SAR framework — Situation, Action, Result — to clearly communicate impact.

Situation
Action
Result

E-commerce Customer Segmentation

PythonK-MeansSQLTableau
Situation

Customer retention rate dropped 15% YoY, with no clarity on which segments were churning or why.

Action

Cleaned and engineered features from 500k+ rows of transaction SQL data. Applied K-Means clustering to identify 5 distinct behavioral segments. Built a Tableau dashboard for the marketing team.

Result

Targeted re-engagement campaigns increased retention by 8%, saving $3,500/month in acquisition costs.

Supply Chain Cost Optimization

PythonXGBoostBigQueryPower BI
Situation

Logistics costs exceeded budget by 22% across 3 consecutive quarters with no predictive visibility.

Action

Built an XGBoost regression model on 2 years of shipping data from BigQuery. Identified top 9 cost drivers and created a Power BI report for operations leadership.

Result

Model achieved 91% prediction accuracy. Recommendations led to a 14% reduction in quarterly logistics spend.

A/B Test: Homepage Conversion Uplift

PythonStatisticsSQLLooker
Situation

The product team proposed a new homepage layout but lacked a rigorous framework to measure impact on sign-up conversion.

Action

Designed and ran a two-sided A/B test for 3 weeks covering 45k users. Used Chi-square tests and bootstrap confidence intervals to validate statistical significance.

Result

Confirmed a statistically significant 2.3% uplift in conversion (p < 0.05), translating to an estimated $8,000/month in additional revenue.
