12 Yrs | Full-Stack Engineer | Scalable App | AI & BLE Integration

Senior Mobile Engineer with 12+ years of experience delivering high-performance, production-ready applications for global clients. I specialize in building scalable cross-platform solutions using Flutter (5+ years) while leveraging deep Native Android (Kotlin/Java) and iOS (Swift/Obj-C) expertise to handle complex integrations that basic developers cannot. What I bring to your project: Full Ownership: I manage the entire lifecycle from architecture design to App Store and Google Play deployment. Complex Feature Mastery: Proven success implementing real-time chat, POS systems, AI integrations, and BLE device communication. Security First: Expert in biometric authentication and secure payment gateways (Stripe, Razorpay, Crypto). Enterprise Standards: I follow Clean Architecture (MVVM/Bloc/Provider), unit testing, and robust CI/CD pipelines to ensure your code is maintainable for years. Technical Stack: Cross-Platform: Flutter & Flutter Web, Dart. Native: Android (Compose, Hilt, Room, WorkManager) & iOS (Swift, Objective-C). Backend & Cloud: AWS, Firebase, Supabase, REST, GraphQL. Media & Hardware: FFmpeg (video/audio processing), BLE, Geolocation. Why Hire Me? I am available 30–40 hours per week and act as a technical partner, not just a coder. I prioritize clear communication, Agile best practices, and delivering a polished UI/UX that users love. Let’s discuss your vision and turn it into a scalable reality.
