Khurram S.

I build fast, reliable, AI-powered mobile apps — native iOS, native Android, and cross-platform with React Native and Flutter. With 15+ years shipping production mobile software, I help startups and growing businesses turn ideas into apps that perform well and stay maintainable long after launch. My recent focus has been on-device AI — using Core ML, Apple's Foundation Models framework, TensorFlow Lite, and Google ML Kit to add face recognition, computer vision, and intelligent features that run privately and quickly on the device instead of a cloud server. WHAT I BUILD • Native iOS (Swift, SwiftUI, UIKit, Objective-C) and native Android (Kotlin, Java, Jetpack Compose) • Cross-platform apps with React Native/Expo and Flutter • On-device AI: Core ML, Apple Intelligence & Foundation Models, TensorFlow Lite, ML Kit, computer vision • Hardware-connected apps: Bluetooth Low Energy (BLE), IoT monitoring, GPS/offline maps • Backend integration: Firebase, Supabase, REST APIs PROOF, NOT PROMISES Recent work includes an on-device AI contact manager for iOS 26 (ContactsAI), BLE-connected environmental and industrial monitoring apps, GPS-based travel apps with offline maps, and React Native apps with Firebase for agriculture tracking, membership management, and personal finance. I'm Top Rated on Upwork with $50K+ in completed projects. If you need a senior developer who can take a mobile or AI feature from idea to shipped product, message me with what you're building.
