Senior Mobile App Developer | iOS & Cross-Platform (React Native)

I’m a senior mobile app developer experienced in building and maintaining production iOS and cross-platform mobile applications for startups and established organizations. Whether you’re launching a new app, modernizing an existing codebase, or stabilizing a live product, I can help you ship reliably and thoughtfully. I specialize in native iOS (Swift / Storyboards or SwiftUI) and React Native development with experience delivering apps to the App Store and Google Play. I’m comfortable working in existing codebases, untangling legacy issues, and improving performance, reliability, and user experience without unnecessary rewrites. I’m product- and delivery-focused with a strong eye for UX, and I regularly collaborate with non-technical stakeholders to translate ideas into practical, shippable solutions. When needed, I can also contribute to HTML/CSS and web-based projects that support mobile products. What I bring: • Native iOS & cross-platform mobile development • App Store & Play Store delivery and maintenance • UX-minded, pragmatic engineering decisions • Full project ownership from planning to release • Clear, consistent communication throughout the project I enjoy working closely with clients to turn ideas into polished, reliable products. Feel free to reach out if you’d like to explore working together.
