Senior iOS Developer | Swift | SwiftUI | UIKit | Apple CoreML & Vision

I build production native iOS apps with Swift, SwiftUI, and UIKit — from architecture and UI through API integration, testing, App Store release, and ongoing maintenance. Clients hire me when they need a reliable developer to take charge of the iOS side of their product: clean architecture, clear communication, and shippable milestones — whether starting from scratch or joining an existing codebase. What I deliver • Native iOS apps in Swift (SwiftUI and UIKit) • App architecture, refactoring, and feature development • REST API / backend integration and third-party SDKs • Firebase, authentication, push notifications, and data layers • Bug fixes, performance improvements, and App Store-ready builds • Clear progress updates and maintainable code your team can extend Also available when needed • React Native or Flutter support on hybrid / cross-platform projects (secondary to native iOS) • Full-stack support with Node.js, React, and Next.js when the project needs web/API work alongside the iOS app How I work I can take a product from idea → architecture → development → integration → testing → release, or step into an existing project and handle the iOS work with minimal hand-holding. I prioritize readable code, solid structure, and practical shipping over flashy demos. If you need a native iOS developer who can manage the mobile app end to end, send a message with a short brief or invite me to the job — I’ll reply quickly with a clear plan and timeline. Remember, communication is the key to a successful project.
