Talha H.

Top Rated Android & iOS developer with completed Upwork work in Jetpack Compose UI, native SDK integration, Stripe Terminal payments, API/authentication integration, and Android compatibility fixes. I help businesses build native mobile features and improve existing apps: matching a design, connecting an API, integrating payments, or investigating a crash. You work directly with the developer implementing and testing the changes. COMPLETED WORK THAT SUPPORTS YOUR PROJECT • Jetpack Compose UI — implemented complex native Android interfaces. • Stripe Terminal M2 — developed an Android application for payment-terminal integration. • Native SDK integration — completed integration work for Android and iOS. • API/authentication integration — connected app functionality with backend services. • Android compatibility fixes — addressed platform compatibility issues in existing apps. SERVICES • Native Android and iOS app development and feature implementation. • UI implementation and refinement using Kotlin/Jetpack Compose or Swift/SwiftUI. • REST API, authentication, Firebase, WebSocket, and mobile SDK integration. • Android payments and POS work, including Stripe Terminal and ESC/POS printing. • Bug fixing, crash/ANR investigation, device compatibility, and performance troubleshooting. • Testing against agreed requirements and a documented code handover. PORTFOLIO EXAMPLES Hidden Camera Detector — native Android and iOS project experience. VoxAide — AI-powered scheduling and meeting assistant. Live Score — football data platform. Share Smart — data-transfer app for Android and iOS. You can review these projects in my Upwork portfolio. TECHNICAL EXPERIENCE Android: 6+ years with Kotlin, Java, Jetpack Compose, MVVM, Clean Architecture, Hilt, Retrofit, Room, Coroutines, and Flow. iOS: Swift, SwiftUI, Xcode, native interfaces, and API/SDK integration. My iOS experience includes SwiftUI development for ScaleOps and native work on Hidden Camera Detector. HOW I START I review the existing app or requirements, identify dependencies, and agree on a practical first milestone. From there, I implement and test the changes and explain what was delivered and what needs attention next. Send me your app, screenshots, or the feature/bug you need help with. I will help define the first step.
