Systems & low-level software engineer focused on Android kernel internals, Linux subsystem architectures, and hardware-accelerated computing on ARM64.
Creator and maintainer of ASL (Android Subsystem for Linux) — an enterprise-grade containerization engine and XFCE4 workstation for rooted Android devices, featuring direct Qualcomm Adreno GPU hardware pass-through via open-source Mesa Turnip Vulkan and Zink OpenGL.
- Linux Kernel & Containerization: Native chroot subsystem execution with private mount namespaces (
--make-rprivate,--make-rslave), eliminating Android host partition pollution (/system,/vendor,/apex) and preventing kernel panics. - Direct Hardware Graphics (GPU): Direct
/dev/kgsl-3d0node pass-through on Qualcomm Adreno 6xx/7xx/8xx GPUs with Mesa Turnip Vulkan 1.3 and Zink OpenGL 4.6, delivering 60 FPS hardware-rendered desktop graphics into Termux:X11. - Low-Latency Audio & Display IPC: Shared-memory X11 display server integration paired with native PulseAudio TCP streaming (
127.0.0.1:4713) under 15ms buffer latency. - Resilient Infrastructure: Autonomous background daemons, 4-tier reverse SSH failover relays (Oracle Cloud VPS, Serveo, Ngrok, LAN), and Android 12+ Phantom Process Killer (PPK) mitigations.
