I build platforms that connect people, systems that think, and tools that developers actually want to use.

About
I'm a Senior Software Engineer (Acting Staff) at Zillow where I architect the Connections & Communications Platform - the system that connects millions of home buyers to real estate professionals across Zillow, Trulia, StreetEasy, and HotPads.
I also lead Symphony, our full agentic SDLC initiative, and built an internal AI Hub with an AI Marketplace, MCP Gateway, and personalization engine. I created AI Catalyst and AI Champions to drive org-wide AI adoption across Zillow Group. Before Zillow, I built platform infrastructure at Illuminate Education and did physics research at Carnegie Mellon.
Outside of work, I'm deep in the agent stack - cataloging the design patterns that make LLM-powered systems actually work in production, building memory engines for AI, and shipping developer tools in Go and JavaScript. Less vibes, more blueprints.
