Uncovered $2M revenue leakage from customer churn
Problem: StaffWise’s revenue growth stalled despite strong signups—nearly $2M at risk from churn & failed payments.
Findings: 84% churn for monthly-plan customers; long-term clients drove 70%+ of revenue loss.

Cut my monthly supermarket bill by 5.16% without buying less
Problem: My monthly supermarket purchases hit KSh. 14,408, likely overpaying by shopping out of habit at Naivas.
Findings: Carrefour alone cut costs by 3.3%, while a mixed-store basket saved KSh 743 (5.16%), with 5 items driving 77.65% of savings.
Fix: Used Excel, Power BI (DAX + dashboards) to compare store-level prices and recommend an optimal shopping strategy.
A one-day look at new Zillow listings in 10 of the largest U.S. cities, visualized through Power BI.
What I Did: Extracted & analyzed 380 Zillow listings with Python and Power BI to reveal pricing and property trends.
Findings:Median price $439.5K, 74% single-family homes; condos led in value ($1,660/sqft). LA & NY skewed averages; Chicago & San Antonio affordable.
Outcome: An interactive dashboard providing actionable market insights.
