Available to hire
I am a senior iOS software developer and architect with 15+ years building and shipping iPhone and iPad apps. I work across the Apple stack (Swift 5/6, SwiftUI, UIKit, Combine, async/await, Core Data, CloudKit, ARKit, RealityKit) and have deep experience with App Store release management, TestFlight, Xcode Cloud, and code signing/notarization. I’ve led Release-1.0 App Store products and contributed to a digital-reader engine powering 40+ live apps. I enjoy taking products from architecture through release, leading iOS teams, and refactoring legacy Objective-C into modern Swift. I also leverage AI-assisted development tools to accelerate iteration and productivity.
I’m comfortable owning a product end-to-end, from architecture to release, and I routinely collaborate with design, content, QA, and security teams to deliver secure, scalable Apple-platform software. I actively apply modern tools and practices to improve code quality, security, and delivery velocity across diverse domains such as healthcare, education, and security.
