Expedia Group · Senior Product Manager · Austin, TX · 08/2024 – Present

I work on Expedia's partnerships from the identity and membership side. I build the account linking that connects Expedia members to our loyalty and AI partners, and the permissions that keep those connections safe.

• I lead account linking for Expedia with AI partners like OpenAI, Anthropic, Google, Meta, and Amazon, so travelers can shop and book with their member prices and saved trips inside AI assistants.
• I bring Expedia membership into partner experiences: member prices, rewards, and the messaging that gives travelers a reason to link their account or book with Expedia.
• I design the consent and authorization model for AI partners: scoped permissions, clear consent, and access travelers can revoke.
• I architected the OAuth 2.0 account linking and consent system behind our partnership portfolio, connecting 20+ global AI, loyalty, and social partners.
• I use AI tools to ship features and experiments to production myself: 50+ changes across UI, APIs, and OIDC, built with Claude Code and ChatGPT Codex.
• I lifted booking conversion 1% by aligning loyalty, fraud, privacy, and security teams on an A/B test of longer sign-in sessions.
• I removed an external authentication vendor through a rearchitecture, saving millions of dollars a year.
