I'm a professional Android Developer having 4+ years of experience in Native Android Development. I have worked for some popular clients including VISA, Pepsi, Lenovo, Adobe, HP, Pinterest, Cloudflare, Warner Brothers, and many others.
I know both Kotlin and Java for Android App Development. I prefer using MVVM and MVI architecture for building Android apps. For the UI, I can use both Jetpack Compose and XML (with two-way DataBinding) for your apps. For clear separation of concerns, code maintainability, and fast build times, I use a multi-modular approach for Android Projects.
I always make sure to write Unit Tests, UI Tests, and Integration Tests for all the code. For Jetpack Compose projects, I use layout debugging and layout inspection to make sure there are no unnecessary recompositions. This makes sure your apps run as fast as possible.
I have great experience in Version Management tools including Git and GitHub.
I have extensive experience working in cross-functional teams where I have interacted with people from different regions all over the world. I have excellent communication skills.

I am a Senior Android Developer and Android Platform Engineer with deep expertise in AOSP development, firmware customization, and embedded Android systems—ranging from development boards to commercial smartphones, tablets, kiosks, wearables, Android TV devices, and IoT controllers.
My professional journey includes building and maintaining production-grade Android platforms for global products and startups. I have delivered system-level Android solutions at EvolaLabs, where I worked on firmware customization, platform optimization, OTA infrastructure, and remote device management systems deployed on real-world commercial devices.
With a strong command of the Android source tree, Linux-based systems, and embedded hardware integration, I specialize in building reliable, production-ready Android platforms tailored to specific business requirements. I help OEMs, startups, and product teams transform standard Android into customized solutions—whether it’s a locked-down kiosk device, a white-labeled firmware product, or a custom Android-based IoT system.
Key Competencies:
* Full-Stack AOSP Customisation – Frameworks, HAL layers, SystemUI, native daemons, init configurations, and system properties
* Firmware & System Customisation – Boot animation, shutdown UI, system branding, performance optimization, bloatware removal, and kiosk enforcement
* Android Wearables & TV – Experience in developing Android TV applications and adapting AOSP for wearable and embedded Android devices
* SDK / NDK & JNI Expertise – Bridging native performance with system-level Android APIs and optimizing low-level functionality
* OTA System Implementation – Server and client development for A/B and non-A/B updates, successfully deployed on production devices
* Remote Access Tools – ADB over network, web-based screen viewing, remote debugging, and full device control solutions
* IoT Integration – Deep experience building Android-based controllers using Zigbee, Z-Wave, MQTT, and hardware communication protocols
* Enterprise Android Platform Experience – Delivered system-level Android customization, firmware optimization, and device management solutions at EvolaLabs for commercial deployments
Proven & Ready-to-Deploy Solutions:
* Android Kiosk Systems – Securely lock down Android devices with system-level restrictions, dedicated device modes, and enterprise-grade control without relying on user-granted permissions
* Remote Device Management Stack – Secure monitoring, debugging, and management of Android devices via network-based tools, remote shell access, and centralized control dashboards
* Screen Casting to Browser – Real-time device screen streaming and remote viewing through web browsers, ideal for remote support, diagnostics, and device monitoring
* Automated Device Scheduling – Auto-boot, auto-shutdown, sleep, and reboot scheduling for Android devices used in enterprise, retail, and industrial environments
* Boot Animation & Branding Customisation – System-level branding solutions including boot logos, animations, startup/shutdown screens, and firmware personalization
* OTA Update Server & Client – Complete over-the-air firmware update system with secure rollout, version management, and rollback support for production devices
* Device Provisioning & Enrollment System – Automated device setup, configuration, and policy enforcement during first boot or mass device deployment
* System Performance Optimisation Toolkit – Tools and scripts for memory tuning, startup optimization, battery efficiency, and long-term system stability
Why Clients Hire Me:
* Source-Level Android Expertise – I work directly inside the Android source tree, from frameworks and SystemUI to HAL layers, init scripts, and system services
* Production-Ready Engineering – I design and deliver stable, scalable Android systems built for real-world deployment across commercial and enterprise devices
* End-to-End Platform Delivery – From hardware bring-up and firmware development to OTA rollout and long-term maintenance, I manage the complete Android system lifecycle
* Strong AOSP & Embedded Systems Knowledge – Deep understanding of Android internals, Linux-based systems, and hardware integration for embedded and custom Android devices
* Reliable Communication & Fast Execution – Clear technical communication, structured delivery, and consistent progress updates throughout the project lifecycle
* Scalable Device Solutions – Experience building Android platforms capable of running reliably on large fleets of devices in production environments
* Problem-Solving at System Level – Skilled in diagnosing complex platform issues, optimizing performance, and implementing robust system-level solutions

Building a high-performance mobile application requires more than just writing code—it requires a robust architecture that can grow with your business. Whether you are launching a greenfield project or need to refactor a legacy codebase, I specialize in delivering production-ready mobile solutions that are clean, testable, and easy to maintain.
My core expertise lies in Kotlin Multiplatform (KMP). I bridge the gap between Android and iOS, helping teams reduce development overhead and codebase maintenance by sharing logic without sacrificing native performance.
Why work with me?
Architectural Rigor: I don’t just implement features; I build systems. My work is anchored in Clean Architecture, MVI, and MVVM patterns, ensuring your app is built to scale.
Proven Delivery: I have a track record of shipping complex applications—from ride-hailing platforms like Feres to secure, high-traffic messaging apps—handling everything from UI implementation to intricate backend integration.
Modern Workflow: I leverage AI-assisted engineering to accelerate development and debugging, applying rigorous human engineering judgment to ensure your product remains rock-solid and secure.
My Technical Stack:
Frameworks: KMP, Compose Multiplatform, Jetpack Compose.
Architecture: Clean Architecture, MVI, MVVM, Multi-module Gradle.
Backend/Integration: Ktor, Retrofit, REST APIs, DTO mapping, Error Handling.
Database/Storage: Room, DataStore, Firebase, FCM/APNs.
Advanced Features: Maps, Location Tracking, Chat, Media (ExoPlayer/CameraX), QR Scanning.
Recent Success:
I recently led the KMP frontend refresh for the Feres suite (Ride-hailing, Driver, and Delivery apps). This project required complex platform-specific implementations (expect/actual), seamless push notifications, and high-performance UI implementation using Compose.
