David Kwartler

Identity nerd, travel-tech PM, occasional race car driver

I build identity and authorization products for AI agents with OAuth.
Also: Porsche, vinyl, and a cat named Rey.

What I do

Identity, consent, and AI agents.

Identity connectivity

I build the OAuth and OIDC systems that let travelers connect their Expedia accounts with loyalty programs, social platforms, and AI experiences. Done well, account linking is a growth engine.

AI agent authorization

I design how AI agents get permission to act for you: the consent and access models behind Expedia's MCP-based Gen AI integrations.

PM who builds

I prototype with AI and ship production changes myself, from UI design to API and OIDC changes. It's the fastest way to test an idea.

Where I've been

Consulting, electric cars, and travel tech.

My work enables personalized search, member pricing, and saved trips across industry-first Gen AI surfaces, safely and transparently.

I lead authorization strategy for Expedia's MCP-based Gen AI integrations like ChatGPT and Claude, building the identity and consent layer that enables personalized search, member pricing, and saved trips across industry-first agentic surfaces.

I achieved a 1% booking conversion uplift by aligning loyalty, fraud, privacy, and cybersecurity teams to A/B test an extended session length strategy.
I eliminated an external vendor dependency for authentication through system rearchitecture, delivering multi-million-dollar annual savings.
I launched social login and a NAVER Pay integration in South Korea, capturing millions in incremental value by improving conversion in a key growth market.

Who I am

Chasing momentum and catching eighty shows a year.

I grew up in Boston, studied in DC, and landed in Austin. Live music is my thing, and the vinyl collection is the receipt. I'm a big fan of track days in a Porsche or Corvette, and gravel bike rides on the Town Lake trail. I travel for vegan food, music festivals, and modern art museums. At home, my cat Rey is in charge.
