Android,Windows,native.

I build across Android, low-level runtime surfaces, and service backends.

A short overview of the systems I work on, the tools I keep close, and the boundaries I prefer to keep legible.

Projects

Featured work.

One project for now, shown with enough detail to make the architecture and judgment visible.

Android / Security Native Android security tooling

Duck Detector

Duck Detector surfaces detector cards for bootloader state, LSPosed / Zygisk traces, native root evidence, virtualization, TEE attestation trust, and other integrity signals while keeping most analysis local to the device.

A device-side Android security inspection app built around modular detectors instead of one monolithic scan flow.

  1. Local evidence collection for root-related tampering, runtime hooking, mount manipulation, attestation trust, and virtualized execution environments.
  2. Kotlin-first app layer with Jetpack Compose, feature-scoped packages, view models, repositories, coroutines, and DataStore-backed settings.
  3. Native probes through the Android NDK with C++, CMake, and arm64 assembly paths where syscall timing or mount visibility matters.

Stack

By layer, not by habit.

The language changes with the boundary, runtime, and failure mode.

Core

Core Languages

Lower-level work where control, layout, and runtime behavior matter most.

Application

Application Languages

Languages used to ship user-facing apps, services, and flexible product surfaces.

  • TypeScript
  • JavaScript
  • Java

Platform

Systems and Platform

Operating systems and platform-specific areas that shape how software lands in the real world.

  • Linux
  • Windows Kernel
