About Me

I'm a results-driven analyst with experience spanning fintech, government infrastructure, social products, and conservation research. I build the SQL and Python pipelines that move data, the R and causal-inference methods — difference-in-differences, instrumental variables, hypothesis testing — that make the analysis defensible, and the Power BI and Tableau dashboards that put the answer in front of the person who has to act on it. I'm currently completing a B.A. in Data Analytics at Denison University, graduating May 2026.

Aug 2025 - Sep 2025
  • Cut issue-resolution tracking time by 40% across a $478M World Bank-financed infrastructure project by building a live operations dashboard with automated Node.js data feeds — field teams could spot supply gaps the moment they happened instead of waiting on weekly reports.
  • Eliminated manual weekly data-pulling for regional managers by wiring the pipeline directly into the dashboard, replacing stale exports with always-current numbers.
  • Presented findings directly to World Bank project leads and government ministers, framing each readout around recommended next actions rather than raw figures.

Jun 2024 - Aug 2024
  • Grew retention 25% on Raaz, a 1,000+ user anonymous social app, by building behavioral pipelines that pinpointed exactly where users were churning.
  • Lifted user satisfaction to 95% on PreTern, an AI career platform used by 411+ students across 3 schools, by mining interaction logs to rebuild the coaching curriculum around what the data showed.
  • Built the core matching engine for Enroll AI, scoring colleges against student profiles using U.S. Dept. of Education data — solving for international students whose transcripts don't map cleanly to U.S. admissions standards.
  • Ran all three products in parallel, each with its own pipeline, KPI framework, and user base.

Portfolio Risk & Optimization Analysis
Python, NumPy, SciPy
Sharpe 0.48 → 0.60
Built a mean-variance optimization model on a $1M, 7-asset portfolio. The rebalanced allocation raised the Sharpe ratio from 0.48 to 0.60 while cutting volatility, then I stress-tested it against a 2008-style shock where 1-day VaR nearly tripled to $38,000.

Customer Churn Prediction

0.84 ROC-AUC
Predicted churn for 7,000+ telecom customers comparing Logistic Regression against Random Forest (80% accuracy), then isolated one segment — new, month-to-month, $65+/mo — churning at more than 2x the base rate.

County-Level Difference-in-Differences: Data Centers & Power Plant Emissions in Ohio
Causal Inference
Causal, not correlational
Used difference-in-differences to show that data center expansion causally raised county-level power plant emissions in Ohio, ruling out confounds that a simple correlation would have missed.

SQL Business Intelligence Case Study
SQLite, Python
12 BI queries
Wrote 12 SQL queries against a multi-table sales database to answer real business questions, including a finding that heavy discounting barely moved order volume — exposing margin loss that wasn't buying any extra sales.

A/B Test Analysis: Checkout Conversion
Python, SciPy, statsmodels
+48.7% conversion
Designed a fully-powered 30-day A/B test simulation (98% power, p < 0.0001) showing a simplified checkout lifted conversion from 4.1% to 6.1%, backed by a pre-test power analysis, sample-ratio-mismatch check, and bootstrap confidence intervals.

+48.2% conversion
Ran a 30-day A/B test on a UI change and measured a 48.2% lift in conversion (4.14% → 6.14%), significant at p < 0.05 — a clean enough result to make a product decision from.
