Profile
Data scientist with six years turning noisy product data into decisions people act on. Equal parts modeling and plumbing: I build the pipeline, ship the model, and then make sure someone actually reads the result. Happiest when a dashboard changes a meeting.
Experience
Data Scientist
- Built a churn model that flags at-risk accounts a month out; retention plays off it recovered an estimated $1.2M ARR.
- Replaced a fragile nightly SQL job with a tested pipeline in Python and dbt, cutting data incidents by two-thirds.
- Set up experiment tooling so product teams can read A/B results without asking analytics.
Data Analyst
- Owned the executive metrics layer, from raw events to the numbers on the board deck.
- Taught a weekly SQL clinic that took self-serve reporting from a bottleneck to routine.
