About

I build products that move revenue at scale, and I've done it from blank repos, in three companies, across two continents.

I'm a Sr. Product Manager at Amazon with 10+ years in product and 16 years in tech. Today I own multi-format advertising at Amazon Ads, unlocking new ad formats through GenAI. My current GenAI creative product influences 2.1% of all platform video ad spend with a 96% creative acceptance rate in beta.

Before this I led streaming monetisation on Prime Video, launched the EU's first IAB-certified CMP for TV at Joyn, and built Disney+ Hotstar's ad platform from scratch, scaling it to a then world-record 25M concurrent viewers and 3B+ ad impressions per day during the Cricket World Cup and IPL.

A note on titles: I've optimised for scope over title. Each role has expanded the surface I own, from a single exchange, to a TV ad stack, to a hyperscaler ad platform, and the work compounds. The role I'm looking for next is Principal PM on a consumer surface where that compounding pays off.
