About

I'm a data analyst, and I'm at my best on the early, uncertain questions: what's worth building, who it's for, and whether the numbers add up. I've done analytics for almost a decade across pretty different worlds: shopper insights at PepsiCo, marketing and incentives at Amazon, then loyalty and attribution at Revolut. The settings changed a lot but the job didn't: take something vague and turn it into something a team can decide on. Now I'm at Cleo, leading analytics on the Discovery Squad. We look at potential new product bets, how big the market is, who'd use it, whether the economics work. It's early-stage and messy, which is the part I like most. I care most about making the analysis useful and explaining it clearly to the product, design and commercial people who act on it. Curious by nature, and I like learning from the people I work with.
