Hire the Best Jetpack Experts Specialists

Need a native Android app built right the first time? I'm a Kotlin/Jetpack Compose developer with 5+ production apps shipped to the Google Play Store — including POS/billing systems, QR attendance trackers, and productivity tools — with hands-on experience across the full lifecycle, from UI design to release. I work across feature implementation, REST API integration (Retrofit/Ktor), MVVM/Clean Architecture, local data storage (Room/Realm), background processing, and Firebase-backed services — with a strong focus on clean, maintainable code rather than just "working" code. Core stack: Kotlin (Coroutines & Flow) + Jetpack Compose MVVM / Clean Architecture REST API integration, Ktor, Firebase Local storage & background processing (Room, WorkManager) Monetization: Google AdMob, Play Billing, RevenueCat If you need an Android developer who communicates clearly and cares about code quality as much as deadlines, let's talk about your project.

I have experience about Java, Kotlin and Flutter. I worked Android about 8 years with many experience about debugging, release app to store, in-app purchase, problem resolving, outsourcing,.. Worked with restful api, web socket, MQTT, IOT, automotive, java backend and many framework. Ready to deliver high-quality Android solutions that meet your project needs efficiently and innovatively.

Senior Android Developer with 6+ years of experience building, improving, and maintaining production mobile applications using Kotlin, Java, Jetpack Compose, Firebase, and modern Android architecture. I specialize in native Android development from building new applications to improving existing codebases, fixing difficult bugs, optimizing performance, integrating APIs and payments, and preparing apps for reliable Play Store releases. ANDROID DEVELOPMENT • Kotlin & Java • Jetpack Compose • MVVM / MVI & Clean Architecture • Android SDK & modern Android architecture • Room, Retrofit & REST APIs • Firebase Authentication, Firestore, FCM, Analytics & Crashlytics • Offline-first applications & local data management • Push notifications & real-time features • Performance optimization & crash debugging • Google Play Store releases, maintenance & updates • Android Enterprise, Device Owner, Kiosk & MDM solutions PRODUCTION & GCC EXPERIENCE I've worked on real production mobile applications, including Saudi/GCC-focused products, Android enterprise solutions, payment integrations, application maintenance, and production release workflows. My experience includes solving real engineering problems rather than only building demo applications including application crashes, device-specific issues, API integration, offline functionality, release problems, and Android device-management requirements. FLUTTER DEVELOPMENT — SECONDARY SPECIALIZATION When cross-platform development is the better choice, I also build Flutter applications for Android and iOS using Dart, Firebase, REST APIs, responsive UI, state management and production release workflows. I have real Flutter projects and live applications, allowing me to work across both platforms when a project requires it. iOS EXPERIENCE I also have experience working with iOS applications and Swift, including modifying, maintaining and publishing existing iOS/Android applications. WHY CLIENTS HIRE ME • 6+ years of mobile development experience • Native Android development with Kotlin and Java • Strong Jetpack Compose and modern Android architecture experience • Production experience with Firebase, APIs, payments and Play Store releases • Android Enterprise / Device Owner / Kiosk experience • Real Flutter experience for Android + iOS • Experience with Saudi/GCC-focused mobile products • 5-star Upwork reviews on completed projects I’m a strong fit if you need: → A Senior Android Developer for a new or existing Kotlin application → Jetpack Compose development or Android modernization → Android bug fixing, crash investigation or performance optimization → Firebase / REST API / Room / Retrofit integration → Android Enterprise, Device Owner, Kiosk or MDM development → Flutter development for Android and iOS → Help preparing and maintaining an application for Google Play or App Store release If you already have an application, send me the current tech stack, the problem you're facing, and your desired outcome. I'll focus on the technical solution and give you a clear approach before development begins.

I am a Senior Software Architect and Mobile Engineer with over 7 years of experience and a track record of 70+ successful project deployments. I specialize in building, scaling, and optimizing enterprise-grade mobile applications. My core focus is native and cross-platform mobile development, supported by deep expertise in full-stack infrastructure, high-performance networking, and modern AI integration. Whether you need to architect a complex application from scratch or optimize, polish, and extend an existing platform, I provide end-to-end technical execution. By leveraging multi-modular Clean Architecture, I ensure your codebase remains highly testable, maintainable, and scalable under massive user loads. Furthermore, I utilize AI-driven development workflows, including Cursor and GitHub Copilot, to accelerate development timelines. This allows me to rapidly audit legacy code, safely refactor, and deliver premium results significantly faster than traditional workflows while strictly maintaining code quality. Core Technical Expertise: 1. Mobile Architecture & UI: Native Android (Kotlin, Jetpack Compose), iOS, Flutter, and Kotlin Multiplatform Mobile (KMM). 2. Enterprise System Design: Multi-modular Clean Architecture, MVVM, MVI, and strict adherence to SOLID principles. 3. Full-Stack & Advanced Networking: End-to-end backend and responsive front-end development, integrated with high-performance gRPC communication and REST APIs. 4. AI Integration & Automation: Implementing LLMs, building custom intelligent workflows, and leveraging AI coding assistants for rapid iteration. 5. Niche Hardware/OS Capabilities: Custom AOSP ROM development and OS-level modifications for specialized enterprise devices. The Strategic Value I Bring: 1. Rapid Codebase Auditing & Optimization: I excel at diving into existing projects, identifying bottlenecks, and implementing immediate performance improvements without disrupting active users. 2. End-to-End Ownership: Because my skills span from the backend network layer (gRPC) to the mobile user interface, I can architect, build, and optimize your entire stack. 3. Consultative Approach: I operate as a strategic technical partner, prioritizing proactive communication, transparency, and precise alignment with your business goals. Please reach out to discuss your project requirements, and we can map out a robust technical strategy for your application.
