I build and maintain iOS and Android applications, from technical planning and development to backend integration, testing, and App Store/Google Play releases. With 7+ years in mobile engineering, I’ve worked on enterprise applications and products built from the ground up. I help clients choose an appropriate architecture, identify technical risks early, and deliver software they can maintain after launch. Relevant production experience: • AutoPlace: Product and mobile delivery for an automotive marketplace, including listings, search, accounts, location features, integrations, and releases. • DirtConnect: Flutter marketplace development, API and real-time backend integration, debugging, and production releases. • React Native media applications: Frontend and UI rebuilds using client-supplied APIs, covering playback, navigation, state management, performance, and release support. • Chick-fil-A, CVS Health, and WOQOD: Enterprise iOS contributions spanning delivery tracking, reusable authorization components, maps, networking, and production improvements. • Clinical StudyPal and ExpoPass: Apple Watch and health-data functionality, payment integrations, offline workflows, and hardware SDK integration. What I work with • Native mobile: Swift, SwiftUI, UIKit, Kotlin • Cross-platform: Flutter, Dart, React Native, Expo • Backend and integrations: Firebase, Supabase, PostgreSQL, Node.js, REST APIs, WebSockets, third-party SDKs • Payments: Stripe, Stripe Terminal, subscription interfaces, and transaction workflows • Wearables: watchOS, HealthKit, Core Motion, WatchConnectivity • AI: OpenAI/Claude integrations, Core ML on iOS, and TensorFlow Lite on Android • Production delivery: Local persistence, synchronization, connectivity recovery, monitoring, debugging, and store releases How I approach your project: - For a new application, I clarify the requirements, validate the highest-risk features, and structure development around reviewable milestones and working builds. - For an existing application, I review the codebase, reproduce issues, and understand its integrations before recommending changes. I focus on practical improvements that preserve working functionality. - Testing covers real-world conditions such as poor connectivity, authentication failures, denied permissions, payment errors, and interrupted workflows. You’ll work directly with me as an independent engineer, with clear communication about progress, technical decisions, and delivery expectations. Send your scope, designs, existing application, or initial idea. We can discuss the main technical risks, architecture options, and a realistic path to release.
