Services

Analytics as a way to answer a specific question, not reporting for its own sake.

Product analytics

Metrics, funnels, retention, segmentation, user behavior, and investigating the reasons behind changes in product performance.

Experimentation & causal inference

A/B testing, experiment design, and impact evaluation in situations where a conventional experiment is not possible.

Analytics quality

Data collection audits, event analytics, quality control, documentation, and processes between analytics and engineering teams.

Business research

Market analysis, customer behavior, and identifying the factors that affect revenue, demand, and product economics.

Specialized expertise — restaurants & foodservice

I understand the restaurant business from both the operational side and the B2B software side. I can work with sales, average transaction value, menu performance, traffic, seasonality, outlet efficiency, and other problems where industry context matters as much as the data itself.
