Muhammad U.

I am a Senior Android Developer and Android Platform Engineer with in-depth expertise in AOSP development, firmware customization, and embedded Android systems—from development boards to commercial phones, tablets, wearables, and Android TVs. My journey includes working at Sony (Lund, Sweden) where I contributed to system-level feature integration and cross-version platform adaptation on Xperia devices using Generic System Image (GSI).

With a strong command of the Android source tree, I specialize in building custom ROMs, extending framework services, developing native system apps, and implementing HAL layers for new hardware. I help OEMs and startups tailor Android to their vision—whether it's a locked-down kiosk experience, a white-labeled firmware product, or a custom Android-based IoT hub.

Key Competencies:

• Full-Stack AOSP Customization – Frameworks, HALs, SystemUI, native daemons, and system properties
• Firmware Modding – Boot animation, shutdown UI, system branding, bloatware removal, kiosk enforcement
• Android Wearables & TV – Experience in developing Android TV apps and adapting AOSP for smart wearables
• SDK/NDK & JNI Expert – Bridging native performance and system-level Android APIs
• OTA System Implementation – Server + app for A/B & non-A/B updates, successfully deployed on 50K+ devices
• Remote Access Tools – ADB over network, web-based screen viewing, full remote control solutions
• IoT Integration – Deep experience building Android-based controllers using Zigbee, Z-Wave, and MQTT
• Sony Experience – Contributed to Android S, T, and U adaptation and feature testing for Xperia phones; worked with GSI, CTS, and system service integration
