Building a fully customized Android OS for HP's enterprise tablet portfolio, working directly in the AOSP tree from board bring-up through GMS certification.

• Owned end-to-end AOSP build process — repo manifests, product makefiles, Soong build rules, and vendor blobs for custom tablet hardware.
• Set up Raspberry Pi (RPi) AOSP builds as development & validation targets; managed kernel config, device trees, and boot image generation.
• Led Android version migrations — ported customizations across major Android releases, resolving API deprecations and framework breaks.
• Architected a custom home launcher from scratch: app-grid, widget host, dock, quick-settings shortcuts, and enterprise MDM policy hooks.

• Implemented split-screen (multi-window): divider drag handle, resizing callbacks, min-size enforcement, per-app multi-window flags.
• Engineered system-wide UI animations — window transitions, enter/exit animators, shared-element continuity effects.
• Built app pinning (screen pinning) end-to-end: SystemUI lock overlay, back/home interception, secure unlock confirmation.
• Integrated Google Mobile Services (GMS); optimized system partitions and boot flow for faster cold-start times.
• Deployed privileged system apps for user profile management and device policy enforcement (Device Owner / MDM hooks).
