I’ve been shipping production software since 2012.

I started in 2012 at UC Santa Barbara’s Earth Research Institute, where I built the NEES@UCSB seismic data portal, real-time dashboards for permanently instrumented borehole sensor arrays, and websites for the institute’s research groups. I spent the next four years at The Mobile Majority (later Gimbal, now Infillion) building mobile advertising infrastructure: real-time microservices handling campaign tracking at scale, and the client-facing platform on top of them. The DSP dashboard I led there won a 2015 UX Award. At ProducePay I led architecture for the Pre-Season financing platform and helped build the trading platform, including the messaging system growers and distributors use to negotiate trades.

I joined Honeyin 2019 and spent five years there as a Senior Staff engineer, through its $4 billion acquisition by PayPal. The extension served 20 million people across 30,000+ retailers and generated hundreds of millions of dollars a year. I designed and built Honey’s first iOS browser extension, ported the legacy Safari extension to Apple’s modern extension API, led the effort to break up and test the extension monolith, and built the A/B testing platform that every Honey development team adopted. During the acquisition I led the extension’s integrations with PayPal’s credit and checkout products.

In 2024 one of Honey’s co-founders invited me to help start Pie, a free ad blocker that grew past two million users. I led the Creator Network, a system that let YouTube creators partner with Pie so supporters could choose to unblock their ads. I owned the iOS and Safari extensions end to end: Swift, Xcode Cloud deployment, and Safari’s content-blocking APIs. When the company became ZeroClick and pivoted to building infrastructure for AI-agent commerce, I built agent-facing APIs and MCP servers, and shipped the company’s first product built entirely through AI-agent development: pie.yt, an ad-free YouTube viewer I owned from conception to launch.

I’ve also designed, built, and shipped two products alone. TrueRate was a Chrome extension that exposed the hidden fees (resort, wifi, parking) buried in hotel listings on Expedia, Hotels.com, Travelocity, and Orbitz, with a scraping API and an iOS app behind it. Unhabit is an iOS Safari extension that blocks distracting sites with cooldowns and scheduling, all on-device. The two reached tens of thousands of installs between them.

Now I consult independently from Los Angeles. Most of my work has been platform engineering inside products that millions of people use: extension APIs, Apple’s toolchain, agent protocols. I like small teams, clear scopes, and shipping.
