Featured Projects

Custom Game Engine + Multiplayer 3D FPS

▸   Vulkan · DX12 · Metal cross-platform

C++ SDL3 Vulkan DirectX 12 Metal

C++ engine on SDL3 / SDL_GPU dispatching natively to Vulkan, DirectX 12, and Metal. Authoritative netcode with client prediction + lag compensation. PBR, cascaded shadow maps, GTAO, SSR, volumetric lighting, SMAA T2x.

GPU Kernel Optimization · CUDA / OpenCL BLAS

▸   85 % of cuBLAS SGEMM on RTX 4090

CUDA OpenCL Nsight

Dense GEMM with shared-memory tiling, warp-shuffle reductions, and register micro-tiling. Nsight + roofline analysis on RTX 3090 / 4090.

Multi-Region GPU Inference Cluster

▸   Self-hosted Kubernetes, 6 GPUs, multi-site

Kubernetes vLLM LoRA Prometheus

Bare-metal Kubernetes across multiple sites for vLLM serving + LoRA finetuning experiments. Prometheus / Grafana telemetry.

Post-Quantum Encrypted Messaging

▸   Kyber-1024 + X3DH + Double Ratchet

Go TypeScript Electron

E2E encrypted chat with identifier-free relays + custom anti-DPI TLS obfuscation. Go backend, TypeScript / React / Electron client.

 

Experience

▸   Upgrading fintech infrastructure at Polity Network — took a single-EC2 monolith to a real AWS EKS cluster with OpenTofu + ArgoCD. Ephemeral per-PR review environments cut the release cycle ~40 %.

▸   Bringing Google Pixel SoCs up over PXE for a 20,000-phone datacenter at UCSD × Google. Living in the bootloader / kernel layer — UART debug, porting Android kernel modules into mainline Linux.
