Summary
👤
Senior🎓
Top SchoolRyo Tulman is an experienced mobile engineer with 12 years building and shipping iOS and Android apps for startups and enterprise clients, currently supporting and modernizing HeadLight’s Fieldbook iPad app while porting it from Objective-C to Swift and SwiftUI. He has led mobile SDK development for location analytics at AreaMetrics—designing battery- and bandwidth-conscious SDKs used by apps with millions of users—and implemented Android MVVM apps in Kotlin for white-label large-venue mapping at Point Inside. Comfortable across Objective-C, Swift, Java/Kotlin, and with backend exposure in Go and Ruby, Ryo blends low-level lifecycle problem-solving with product-focused feature delivery. He’s shipped interactive, animation-rich consumer features (from karaoke video recorders to complex UI transitions) and architected concurrent network controllers to keep UIs responsive. Based in McKinney, Texas, he pairs a philosophical BA from Brown with practical bootcamp training in iOS development, a mix that informs thoughtful, user-centered engineering decisions. Notably, his work often spans SDKs, platform ports, and cross-team support—roles that require both deep debugging skill and product empathy.
