At People Tech, I build and optimize AOSP platform components for MediaTek and Qualcomm production devices, focusing on native services, IPC, SELinux policies, and system performance.

I develop custom Android system services with AIDL/HIDL, create JNI libraries for proprietary binary protocol decoding, and integrate HAL properties to connect native signal data with Android framework layers.

I've improved boot time, memory usage, runtime performance, and power-state behavior through low-level framework and native code changes. I also integrate OTA update mechanisms, native shared libraries, privileged system applications, and customized launcher and branding experiences into AOSP builds.

I drive bug triage, root-cause analysis, code reviews, and production fixes using ADB, GDB, Logcat, Git, Gerrit, shell scripts, and automated diagnostics. My earlier Android development internship gave me hands-on experience with Java, Android SDK, APIs, architecture components, Binder IPC, and core Android components.
