Rockstar🎓
Top SchoolMorten Ditlevsen is a seasoned iOS engineer, product specialist and founder with over 14 years building apps and leading platform teams since before the first iPhoneOS SDK. He has been the sole developer on influential products like Grindr at launch, led iOS architecture for a company with 350+ App Store apps, and designed horizontally scalable commerce systems with low-maintenance cloud backends. A pragmatic technologist fluent in Swift, SwiftUI and Cocoa frameworks, he contributes to Swift core projects (including an accepted Swift Evolution proposal) and improves widely used OSS like Firebase and Leaflet. Known for clear communication and customer-facing architecture work, he blends hands-on development, teaching and product thinking across startups and enterprise clients. Less obvious: he pairs deep low-level experience (Core Foundation, profiling and debugging) with front-end UI work such as TokamakGTK integration, making him effective across the full mobile stack.
