I played a leading role in helping Cazoo transition to a pure‑play automotive marketplace business model. This included:
- Contributing to a series of experiments to learn how consumers might sell their car to a dealer through a Cazoo auction platform.

Cazoo Operations

I contributed significantly to the rapid scaling of operations at Cazoo, building processes and technology from the ground up across multiple domains. Key achievements include:
- Created a solution to enable middle‑mile logistics planning and execution to be brought in‑house, ultimately scaling to support close to 160K used car sales.
- Reduced the launch time for Cazoo Customer Centres from 3 weeks to 1 hour, enabling rapid scaling from 1 to 9 locations in less than 1 month. This expansion increased vehicle handover capacity, ultimately leading to an 8% increase in the overall conversion rate.
