⭐ AI Developer |Senior Mobile App Engineer | iOS · Android · Flutter | AI & IoT | 14+ Years Hi, I’m Manbir Kakkar a Senior Mobile Engineer with 14 years of experience building high-quality iOS, Android, and cross-platform applications used by real customers in production. My core focus is mobile app development, but what sets me apart is my hands-on experience combining AI, IoT, and enterprise integrations (MuleSoft, APIs) into mobile products that scale. I work with startups and product teams who want more than “just an app” they want something reliable, well-architected, and ready to grow. 🚀 What I Do Best 📱 Mobile App Development (Core Expertise) I build production-ready mobile apps from idea → App Store / Play Store → scale. • Native Android (Kotlin / Java) • Native iOS (Swift, SwiftUI, UIKit) • Flutter (Dart) for cross-platform apps 🤖 AI-Powered Mobile Experiences I integrate AI features directly into mobile apps, including: • ChatGPT / LLM integrations • On-device ML (CoreML, ML Kit) • Image processing, OCR, recommendations • Voice, automation, and smart workflows 🔗 Backend & Integration (MuleSoft + APIs) I’ve worked with MuleSoft-based enterprise integrations, REST APIs, and cloud services to connect mobile apps with complex backend systems. • MuleSoft & API-led connectivity • Firebase, AWS (Lambda, API Gateway) • Secure, scalable mobile-backend communication 📡 IoT & Connected Devices I’ve built mobile apps that talk to hardware in real time: • Bluetooth / BLE • MQTT, WiFi-based devices • Wearables & sensor-driven apps 🧠 Architecture & Quality Mindset I don’t just ship features. I build systems that last. • MVVM, MVP, MVI, VIPER • Clean Architecture & SOLID principles • Performance optimization & memory tuning • Strong testing discipline before release 🛠 Tech Stack Snapshot iOS Swift, SwiftUI, UIKit, CoreML, ARKit, VisionOS, Core Data, GCD, Firebase Android Kotlin, Java, Jetpack, Clean Architecture, ML Kit, ARCore, Retrofit Cross-Platform Flutter (Dart), Firebase, REST APIs AI & ML ChatGPT / LLM APIs, CoreML, ML Kit, image & text processing IoT & Networking BLE, Bluetooth, MQTT, WiFi, real-time sync Payments & Integrations Stripe, PayPal, Braintree, social logins Tools GitHub, GitLab, Bitbucket, CI/CD 📈 Why Clients Work With Me ✅ 14+ years of real-world mobile experience ✅ 100% Job Success & long-term client retention ✅ Clear communication & transparent updates ✅ Strong product thinking — not just coding ✅ Comfortable owning features end-to-end ✅ Available and responsive across time zones I’m especially effective when: • You’re building v1 → v2 of a product • You need AI or device integration in mobile • You want someone who thinks like an owner 🎯 Current Focus My long-term focus is mobile-first product development, with AI and integrations used where they create real value not buzzwords.
