About

I’m a self-taught Staff-level iOS Engineer with over 13 years of experience building, scaling, and leading mobile applications used by millions worldwide. My career is defined by a deep curiosity and ability to learn new technologies rapidly and implement them at scale — from iOS frameworks and build systems to backend automation and AI-powered product features. At Slack, I spent 9+ years advancing from early iOS contributor to Tech Lead on the Mobile Developer Experience team, driving large-scale performance improvements across CI, builds, and runtime. I reduced CI Time to Merge by ~6× (65 → 11 min), cut launch times by 50%+, and reduced local rebuilds nearly 3×, accelerating developer productivity company-wide. At Pinterest, I served as a Staff Engineer on the iOS Platform team, where I created Gestalt, the centralized UIKit library powering design consistency across the app, and led the modernization effort to move off legacy UI rendering frameworks. Throughout my career, I’ve designed and implemented core infrastructure spanning caching layers, networking frameworks, reusable UI components, and build automation pipelines built on Bazel, Buildkite, and Jenkins, alongside AI agents and backend services that power large-scale mobile systems. If you’re looking for a results-driven engineer who can learn new technologies quickly, execute at scale, and lead teams to deliver exceptional mobile experiences — let’s connect.
