I help startups and businesses build, improve, and maintain mobile applications with a strong focus on user experience, performance, security, and long-term maintainability. I have 8+ years of experience in mobile app development and have worked on iOS, Android, React Native, and Flutter applications for businesses across different industries. My experience includes building applications from scratch, redesigning existing apps, improving performance, integrating APIs and third-party services, and maintaining existing mobile products. My core expertise includes: -- React Native & React Native CLI -- iOS Development (Swift, SwiftUI, UIKit) -- Android Development (Kotlin, Java) -- Flutter & Dart -- Firebase (Authentication, Firestore, Realtime Database, FCM, Analytics, Crashlytics) -- REST API & GraphQL Integration -- PHP Backend Integration -- Push Notifications (FCM & APNs) -- Google Maps, Location & Geofencing -- Payment Gateway Integration -- Social Login (Google, Apple, Facebook) -- OpenAI & AI API Integration -- Third-Party SDK Integration -- App Performance Optimization -- Bug Fixing & Existing App Improvements -- App Store & Google Play Deployment -- CI/CD, Fastlane & TestFlight I have also worked app redesigns focused on improving the overall user experience, app performance, and usability. For existing applications, I can work with the current codebase, understand the existing architecture, fix issues, add new features, and improve the application without unnecessarily rebuilding everything from scratch. Whether you need a new mobile application, improvements to an existing app, React Native, iOS or Android developer for your product, or ongoing mobile app support, I can help take it from development to App Store and Google Play deployment.
