AI Engineer @ Zillow

I'm an AI Engineer with mobile, backend, devops, and BI experience. I love building and maintaining software that helps other people. Currently I work at Zillow to deliver a best in class mobile platform experience and AI tools.

Mobile Debug Bridge MCP

Espresso tests are brittle, slow, and require constant maintenance. Product owners and designers have a tough time dogfooding Android apps when their daily driver is an iPhone. Engineers who would like to prioritize great UI performance have a hard time making the case that its worth the effort. Accessibility audits and deep UX research are too expensive and time consuming to run on every change. Have I got something for all of you. This talk will explain the development journey of vibe coding a Model Context Protocol (MCP) server that automates mobile device interaction with Firebender + Claude Sonnet from scratch. I've achieved unprecedented accuracy and speed in analyzing and traversing view hierarchies. I also designed it from the beginning to be able to run in headless mode for CI automation as well as aid local development workflow. What You'll Take Away: • How to build an MCP server from scratch designed for high value outcomes. • Most of the talk will be a live demo of Mobile Debug Bridge in action • How to use Mobile Debug Bridge in your development workflow to improve product usability, accessibility, and more. • How MCPs like this change everything we knew about software engineering.
