12+years across product, growth and go-to-market

I'm a product leader who sits at the intersection of growth, marketplaces and go-to-market. My career at Amazon has taken me from recruiting sellers in India, to educating hundreds of thousands of advertisers, to owning how Amazon acquires Prime members worldwide.

Today I lead growth for Amazon Custom, the experience that lets shoppers personalize products with their own text, photos and designs. I like problems where strategy, experimentation and cross-team alignment all have to work at once, and where the results show up in the numbers.

01Selected work

A few projects that show how I think: find the growth lever, prove it with experiments, then scale it.
