I provide senior iOS engineering for teams building a product, taking over an existing app, or working through reliability and release problems. My focus is hands-on Swift, SwiftUI, and UIKit development, with the backend and integration experience needed to understand the whole system. How I can help • Native app development: implement agreed features and maintainable application architecture. • Inherited-app recovery: review an unfamiliar codebase, diagnose failures, and prioritize practical fixes. • Backend and device integration: connect APIs, authentication, local or cloud data, notifications, and Bluetooth or other SDKs as the project requires. • Release readiness: address performance issues, test critical flows, and support App Store submission. • Technical handoff: document setup, decisions, and remaining work. My portfolio includes lead iOS work for New Digital Commune and native mobile contributions to 1OR Health. I also work with React Native when a cross-platform approach fits the product. Start with a focused app review or a scoped implementation. Consulting is $100/hour, with scope and estimated effort agreed before work begins.
