Simulated impact of DVM operations and non-volatile memory in gem5 (C++, 'Ruby' DSL).

• Added DVM operations to existing gem5 CHI protocol model
• Simulated impact of DVM on many-core systems
• Presented results to key stakeholders and senior design members, including a 'CHI protocol crash course'
• Changes have been upstreamed to public gem5 repo (https://gem5-review.googlesource.com/c/public/gem5/+/57298)

Junior Programmer

Developed 3D game engine in C++/Vulkan/Metal with two senior engineers

• Implemented Physically Based Rendering with Image Based Lighting
• Ported Unity-based code, shaders to C++, GLSL and Metal
• Supported development of AR racing game (Lightstream Racer) in Unity/C#

Applied CHERI-based memory protection to the RISC-V "V" vector extension.

• Researched RISC-V "V" extension and other scalable vector models in depth
• Designed combination CHERI and "V" specification, CHERI-RVV
• Implemented CHERI-RVV support in Clang
• Developed CHERI-RVV emulator in Rust

Created a real-time GPU fluid simulation (CUDA) and parallel visualization (C++/Vulkan).

• Ported a fluid simulation from C to CUDA
• Implemented a GPU visualization in Vulkan
• Implemented various synchronization between CPUs and GPU
• Used memory sharing between CUDA and Vulkan to reduce copying

Built high-performance image filter in SystemVerilog.

• Designed highly performant image filtering kernels (3x3 convolution, 1x1 brightness/contrast)
• Implemented CPU-based real-time brightness adjustment using APB to communicate with the FPGA
• Developed a Python library for converting VGA signals to images for automatic testing

Import/export addon in Blender for the proprietary GMD file format from the Yakuza game series. (Python)

• Reverse-engineered parts of the file format with the community
• Designed algorithms to convert computer-friendly meshes to artist-friendly meshes
• Developed beginner-friendly user experience for new modders
