Cudjoe Augustine

Data analyst with strong SQL and experimentation fundamentals, experienced designing and analysing tests to separate real signal from noise rather than accepting surface-level patterns. Built and delivered dashboards that turn raw data into decisions stakeholders act on, and have direct experience analysing marketing acquisition channels and sign-up funnel data. Comfortable working independently on ambiguous, ad-hoc analytical problems, with a track record of catching and correcting real data issues before they affected business decisions.

MSc in Mathematics provides a rigorous, evidence-based approach to experimentation and causal reasoning.
