I build native iOS and Android apps and cross-platform applications that launch on time, work smoothly, and scale to thousands of users. Most clients hire me after their first app developer disappeared mid-project, delivered buggy code that crashes in production, or built apps that work on one device but break on others. I've developed 30+ mobile applications across iOS, Android, and Native over 7 years. I handle the complete development cycle, from UI/UX implementation to API integration, testing, and App Store deployment. APPS I'VE BUILT: **E-commerce App - (iOS + Android)** Built complete shopping app with product catalog, cart, Stripe payments, push notifications, and order tracking. Launched on both App Store and Google Play with 50K+ downloads. **Fitness Tracking App - Native iOS (Swift)** Developed workout tracking, progress charts, HealthKit integration, and social sharing features. Achieved 4.8★ rating with 10K+ active users. **Delivery App - Native** Created real-time delivery tracking with Google Maps integration, driver matching algorithm, in-app chat, and payment processing across iOS and Android. **Social Networking App** Built user profiles, photo/video sharing, comments, likes, Firebase backend, and real-time notifications serving 25K+ users. **Healthcare Booking App - Native Android (Kotlin)** Developed appointment scheduling, telemedicine video calls, prescription management, and secure patient data handling.
