Hi, I'm Brandon Keck πŸ‘‹

Business Analyst at Sapporo USA Β· M.S. in Data Science, Cal State East Bay (2026)

I turn messy business questions into clear, data-backed answers. My background is in applied statistics and predictive modeling, and day to day I work across SQL, dashboards, and stakeholder analysis to help teams make better decisions.


πŸ” What I Do

  • Process automation: streamlining manual workflows with Python and Power Automate
  • Forecasting & machine learning: building predictive models to forecast business trends
  • Reporting & dashboards: building self-serve reporting in Power BI, with experience in Tableau
  • Business analysis: defining KPIs, gathering requirements, and translating stakeholder questions into analyses
  • Statistical modeling: regression, classification, hypothesis testing, and resampling methods

πŸ“Œ Featured Projects

Project Description Tools
Olist E-Commerce Analysis SQL analysis of 100k orders across 9 tables. Found that late deliveries (7% of orders) cause ~37% of 1-star reviews and that the true repeat rate is only ~2.2%, with recommendations for delivery and retention. SQL (DuckDB), Python
CFB Power Ratings Elo-style rating engine built on multi-season CollegeFootballData API data. Backtested on every FBS-vs-FBS game since 2019 at 71.4% accuracy (+12.6 pts over a home-favorite baseline), with weekly automated updates and a live dashboard. Python, GitHub Actions, Chart.js
Titanic Survival Prediction End-to-end classification pipeline comparing six models with stratified 5-fold CV and GridSearchCV tuning. Final Random Forest reached 83.7% validation accuracy and 0.890 AUC. Python, scikit-learn, XGBoost
