Daniel Kilders is an independent iOS developer who designs and builds applications from initial product concepts through App Store release and subsequent improvements. His practice connects user experience, interface design and engineering, with Swift and SwiftUI at the centre of his work. Personal projects include Bamboo, an offline-first baby tracker, Bottomline, a budget planner, and SwiftStudy, a flashcard learning application. These products explore widgets, family synchronisation, charts and other native platform capabilities where useful to the task. His portfolio distinguishes independently released products from contributions made within company teams. It also includes Northlight, a feedback platform connecting mobile software development with product planning.
