Architecture

I've designed and scaled platforms across web, backend, cloud, and communications systems. Most recently, I took a one-week AI agent prototype to the advisor desktop that now handles most of Rivian's inbound and outbound calls and chats, on top of the platform migration and real-time messaging that 4,000+ support agents rely on.

Product delivery

I turn ambiguous customer and operational problems into products that ship and move numbers, like the AI chatbot I drove from architecture to launch, now ~12% of customer acquisition.

Technical leadership

I set technical direction, get stakeholders aligned, and mentor the engineers around me, while staying hands-on in the implementation paths that actually ship.
