Senior🎓
Top SchoolPorterfield Porterfield is a Principal Software Development Engineer based in Seattle with 12 years of hands-on Android engineering experience, primarily in financial services and consumer applications. At Zillow and prior at JPMorgan Chase and L Brands, he has led migrations to Kotlin, driven architecture shifts toward MVVM, and implemented CI/CD and reusable component libraries that improved developer velocity and UX consistency. He combines deep mobile technical craft—rewriting core libraries, converting AspectJ to debuggable annotation-based aspects, and expanding analytics coverage—with a pragmatic focus on delivery and testing. Outside work he’s an avid hiker and gamer, a background that mirrors his balance of persistence and curiosity when tackling complex product problems.
