Sumit C.

Senior Mobile App Developer with 8+ years building native and cross-platform apps for iOS, Android, and Flutter - from first idea through App Store / Play Store launch and post-release support. I have shipped 20+ apps across domains like - healthcare, fintech, e-commerce, Social engagement, Fitness, Wellness etc. Clients come to me when they need an app that actually ships and holds up after launch and not just another working prototype. WHAT I BUILD - Native iOS apps in Swift, native Android apps in Kotlin/Java - Cross-platform apps in Flutter for faster, budget-conscious builds - BLE and IoT-connected apps — real-time communication between mobile apps and hardware devices (a specialty most mobile devs don't touch) - Offline-first apps using Room DB, with Firebase Cloud Messaging for real-time notifications - Clean, scalable architecture (MVVM, Databinding, JetPack/AndroidX) so your app is maintainable long after I hand it off HOW I WORK - I scope clearly before writing code, so estimates hold - I optimize for performance and memory from day one, not as an afterthought - I stay on for post-launch maintenance - I don't disappear after go-live - Build Long term relationships Top Rated on Upwork with a 100% Job Success Score. Message me with what you are building and I will tell you honestly whether I am the right fit and what it will take to ship it.
