Mobile App Developer | iOS, Flutter & Android | Build, Fix & Maintain
Have an app that is unfinished, difficult to maintain, or not ready to ship? I help founders build, fix, and maintain mobile apps for iOS, Flutter, and Android. That can mean taking over an existing codebase, fixing broken flows, completing features, improving the UI, or getting the app ready for release. I have 8+ years of mobile development experience across native iOS (Swift, SwiftUI, UIKit), Flutter, and Android. I work with Firebase, REST APIs, push notifications, subscriptions, StoreKit, maps, and App Store / Google Play releases. I also help founders move beyond Base44, Lovable, Bolt, or Replit prototypes when they need a production-ready mobile app. What I can help with: • Build new iOS, Flutter, or Android features • Fix bugs, crashes, broken flows, and UI issues • Take over and improve an existing mobile codebase • Connect Firebase, APIs, push notifications, maps, and subscriptions • Refactor code and test key user flows before release • Prepare builds for TestFlight, the App Store, and Google Play Selected work: • Love Notes — turned a Base44 app into a native SwiftUI app with StoreKit 2, resolved Apple review issues, and launched it on the App Store. • Nokia — contributed to an enterprise field-service app with offline sync, GPS, and barcode scanning. • Walmart — worked on the pharmacy refill experience using MVVM and Coordinator architecture. • Also contributed to mobile products for Dunkin’, Openbank, Upstox, and Destiny Discover. I communicate clearly, flag risks early, and keep the work focused on the result you need. Send me your Figma design, existing codebase, prototype, or list of issues, and we can discuss the next step.
