I am a senior level iOS app developer serving clients in the Bay Area and beyond. I have 20+ years experience as a professional engineer, the last 6+ of which have been in iOS, and have a background in Computer Science. I have worked on interesting projects in both Swift (my focus since its release), as well as Objective-C. Some recent projects include Ava, a novel app that helps deaf people communicate in group conversations, Twine, an app that helps people start and develop savings plans, and an internal hospital management app for a hospital chain, backed by GraphQL. I have experience in getting existing applications back on track, and also in starting new applications from scratch. From all my professional engineering experience, I have come to appreciate the lasting benefits of clean architecture, and that is my primary focus. Accordingly, I have experience with applications of MVVM, reactive and unidirectional flow architectures, and have written foundational logic for multi-party chat and distributed systems, caching and connecting to REST and GraphQL backends. Beyond my experience in iOS development, I have extensive experience in audio and video processing, system software development, and several years of backend web development.
