Case Studies

Client work

Each case study starts with the decision someone had to make, then covers what I built, how the result was measured, and what changed. Two come from my time at Ringer Sciences, and the rest from independent consulting since 2024. I keep clients anonymous as part of keeping their data confidential, so each case names the kind of business and says what the evidence does and doesn't show.

Dashboards for a Hospital's Physician Marketing

At Ringer Sciences, a large hospital ran a multi-million-dollar marketing program aimed at doctors, and its journal ad data was typed into spreadsheets by hand. I brought it into BigQuery, joined it with the ad platforms, and built dashboards for marketers and physicians. They became a recurring paid product and informed budget reallocation.

Connecting Paid Campaigns to Verified Visits

A cafe, later an event lounge, could see clicks and leads but not who walked in. Dated flyers, phone numbers, and personal offer codes tied campaigns to verified visits and revenue. On lead campaigns, the ad spend behind each dollar of tracked sales fell about 70% after I rebuilt the ad audiences from verified visitors.

A Lead CRM and Call Ranker for a Wholesale Supplier

A wholesale meat supplier's sales team spent hours phoning leads. I built them a bilingual lead CRM on the city's open business data, then trained a model that ranks who to call first. Closing rate per call rose about 50%, from about 8 closes per 100 calls to near 12.

Searching Prior Research in Plain English

At Ringer Sciences, analysts at a B2B media client spent hours searching old reports. I built a search assistant over the company's own documents. Over a one-quarter pilot, the marketing and PR department reported about 40% less research time, and the client kept it as a recurring paid product.

Finding Demand for a New Event Format

Earlier work for the same cafe: it needed a reason for people to come back. Analysis of public local posts pointed to language exchange as underserved. Foot traffic doubled in the quarter after the launch, compared with the quarter before.

Public technical work

The technical work section has projects you can inspect line by line, in NLP, forecasting, data validation, retrieval, and scientific computing.
