Summary
Four years of business analysis across growth and retention. The work isn't reporting — it's breaking a question down until it can be tested, then answering it with an experiment or a quasi-experimental method. Every conclusion ends in a recommended action, and I track what happened after.
Education
2017 - 2021State UniversityB.S. Statistics
Coursework in regression, experimental design and causal inference. GPA 3.7/4.0.
Experience
Feb 2023 - PresentOnline Education CompanyData Analyst
Owned renewal attribution; used propensity score matching to remove selection bias and identified first-month lesson completion as the strongest leading signal, driving a scheduling change worth +6.2pp renewal
Rebuilt core metric definitions into one wide table — three teams had been computing 'active user' differently, and the disputes stopped
Designed and reviewed 34 A/B tests, 11 rolled out; also stopped 5 that looked like wins but weren't significant
Jul 2021 - Jan 2023E-commerce CompanyData Analyst
Built a new-user segmentation into 5 groups with differentiated outreach; 30-day repurchase rose 4.1pp

Projects
Feb 2024 - Sep 2024Churn Early WarningSole owner
Flags high-churn-risk users 14 days ahead for targeted outreach.
Model AUC 0.79 — more importantly, ran it with a holdout so the 3.4pp retention lift is attributable to the intervention rather than to users who would have stayed anyway

Strong SQL: window functions, complex joins, query optimisation
Causal inference: A/B design, propensity score matching, difference-in-differences
Python for analysis and modelling (pandas, scikit-learn)

Three mistakes this example avoids

  • 'Built dashboards and produced daily reports' with no outcome
  • Listing SQL and Excel as the entire skill set
  • No business context — the reader can't tell if the number was big
