🛠️ Tech Stack

Languages C++ C# Python CUDA

Engines & Tools Unreal Engine Unity Perforce

🔥 Featured Projects

1. GAM250 Engine (Custom C++ Game Engine)

Tech Lead (13 members) | Architecture & Core Systems

A custom 2D game engine built from scratch to support a large-scale student team project.

  • Architecture: Designed a Component-based architecture to ensure modularity and flexibility for gameplay programmers.
  • Systems: Implemented custom Physics (AABB/Circle collision), Rendering, and integrated ImGui for debugging tools.
  • Optimization: Managed memory manually and optimized game loops for consistent frame rates.
  • Repository: View Project

2. p4bot (Perforce Automation Toolkit)

Tools Programmer | Pipeline Automation

A self-hosted automation suite to bridge Perforce and Discord, improving team workflow efficiency.

  • Submit Poller: Automated changelist tracking and Discord notifications using PowerShell.
  • Opened Watcher: Real-time monitoring of checked-out files to prevent merge conflicts in exclusive-checkout environments.
  • Slash Command: Developed a Python-based Discord bot (/canwork) for instant file status checks.
  • Repository: View Project

3. CUDA Learning Journey (High-Performance Computing)

Individual Researcher | GPU Optimization

A deep dive into massive parallel computing and hardware-level optimizations.

  • Optimization: Implementing Grid-Stride Loops, Shared Memory Tiling, and Warp-level Primitives.
  • Profiling: Utilizing NVIDIA Nsight Compute to analyze memory throughput and occupancy.
  • Goals: Building a massive Boids simulation (100k+ agents) purely on GPU.
  • Repository: View Project
