About
I am a graphics engineer specializing in Vulkan-based rendering, GPU performance optimization, and rendering architecture for mobile and XR systems. My background spans AR headset rendering, simulation and training platforms, technical leadership in mobile graphics, and reproducible GPU benchmark development.
What I focus on
Building rendering systems that are fast, measurable, and maintainable under real platform constraints such as bandwidth, memory pressure, and synchronization cost.
What I value
Clear architecture, data-oriented thinking, strong profiling discipline, and technical work that can be explained with concrete performance outcomes.
Core expertise
The areas where I bring the most value: graphics architecture, GPU efficiency, and performance-critical engineering for real-time systems.
Performance Engineering
GPU profiling, bottleneck analysis, cache-aware data layout, coalesced access patterns, synchronization strategy, and memory bandwidth reduction.
Engineering Stack
C++, C, GLSL, Python, CMake, Git, RenderDoc, Nsight, Android, Linux, and Windows for production and experimental workflows.
Featured projects
