My key professional achievements include:

Snap Inc. (Software Engineering Manager, 2018-Present): I scaled the notification system 100x from 50 million to 5 billion daily messages by leading its re-architecture from a monolith to a microservice platform. I co-designed an ML pipeline for notification ranking, grew my organization to 24 engineers peak (notifications + profile), and now shifted to focus on solely leading the 12-person Profiles team, a core product surface viewed by over 300 million daily users.

YouTube / Google (Staff Software Engineer, 2008-2018): As the Founding Architect of the YouTube Partner Program, I designed and built the core systems that created the modern creator economy, enabling it to scale to millions of partners and generate billions in annual revenue. I later served as Tech Lead for YouTube Notifications, scaling its delivery to billions daily.

I hold several key patents from my time at Google in areas like video revenue sharing and content recommendation. I graduated with a Bachelor of Mathematics in Computer Science from the University of Waterloo.
