Design-minded engineer shipping high quality, high impact work.

About

I’m currently a New York-based SDE II at Amazon on the Native Commerce Ads (NCA) team, building scalable systems that support millions of daily customers. I care deeply about clear, accessible user experiences where complex and critical workflows become reliable and intuitive to use.

Previously I was a core contributor to Amazon Payments’ Seller Wallet, building the product from the ground up and growing into a subject matter expert across multiple domains.

My work spans backend systems, platform engineering, and end-to-end product flows. Within this scope, I’ve designed shared UI infrastructure and built backend services for key ad and payment workflows. I also led the EU launch of a Third Party Payments feature across seven marketplaces, coordinating engineers across multiple time zones to expand Seller Wallet internationally.

Outside of work I enjoy skiing, photography, and exploring the city I grew up in and still find endlessly interesting.
