Rogue-Lite RPG

Insomnia's Toll: A 3D rogue-lite game featuring multiple weapons, skill tree, and procedurally generated level/boss encounters, and combo-driven combat with hand-crafted ability animations.

Role: Game Designer & Combat Designer | Designed dual-progression system combining temporary run-based upgrades with permanent skill tree unlocks across 20+ abilities, created boss encounter phases with telegraphed attack patterns and combo windows, and animated 12+ player skills with VFX integration for responsive combat feedback through iterative playtesting (15 sessions)

Tools: Unity, C#, Blender, Git, Jira

Game poster & Features available:Link

SMB remake

Precision platformer featuring momentum-based movement, multi-jump mechanics, and shooting combat across modular level designs with tuned difficulty progression.

Role: Gameplay Programmer & Level Designer | Built custom physics engine with tuned gravity and friction parameters, designed modular level blocks enabling 3x faster iteration through XML configuration, and balanced shooting mechanics with multi-jump system achieving 10% difficulty variance across 8 levels

Tools: MonoGame, C#, Python, XNA Framework, Git

Game Demo available:Link

Mini Minecraft - Procedural Voxel Engine

High-performance voxel rendering engine featuring infinite procedural terrain generation, multithreaded chunk systems, and real-time world modification through custom C++ graphics pipeline.

Role: Graphics Programmer | Developed procedural generation algorithms combining layered Perlin and Worley noise for biome blending with cave/river/mountain features, optimized rendering pipeline through frustum culling and VBO interleaving reducing draw calls by 60% and GPU memory by 35%, and implemented multithreaded chunk generation system achieving 60fps real-time terrain modification across infinite worlds

Tools: C++, OpenGL, GLSL, Multithreading, Procedural Generation

Game Demo available:Link

Level Greybox

Interconnected 3D level design featuring non-linear exploration, verticality-driven spatial layouts, and strategic backtracking mechanics through iterative greybox prototyping.

Role: Level Designer | Designed multi-layered environment with branching pathways and shortcut unlocks, established player flow through environmental storytelling and landmark placement, and iterated on spatial metrics for combat encounters and platforming challenges

Tools: Unity, ProBuilder

Dread Drift

A text-based interactive fiction game made with Twine.

Animation

‹

Forward-Inverse Kinematics System

Interactive skeletal animation toolkit featuring real-time FK/IK pose editing, procedural motion generation, and Unity integration for character control systems.

Role: Technical Animator & Programmer | Developed hierarchical transform system with FK solver for BVH motion playback, implemented three IK algorithms (Limb-based, CCD, Pseudo-Inverse) for end-effector control, and created Unity plugin for terrain-adaptive foot placement

Tools: C++, Visual Studio, Unity, OpenGL, CMake

Boid Flocking & Behavioral Animation System

Physics-based crowd simulation featuring autonomous agent behaviors, predator-prey dynamics, and emergent flocking patterns through steering force algorithms.

Role: Technical Animator & AI Programmer | Implemented steering behaviors (seek, flee, wander, obstacle avoidance) with feedback control systems, developed flocking algorithms combining separation, cohesion, and alignment forces, and created leader-following formations with dynamic agent interactions

Tools: C++, Unity, Visual Studio

Motion Capture & Keyframe Animation Pipeline

Full-body character animation workflow combining hand-keyed locomotion cycles, optical motion capture processing, and seamless motion blending for realistic character performances.

Role: Character Animator | Created procedural walk cycles using FK/IK rigging with pose controls, operated Captury mocap system to record 10+ full-body performances, and implemented motion blending with cross-dissolve transitions while eliminating foot sliding artifacts through F-curve refinement

Tools: MotionBuilder, Captury Motion Capture System, FK/IK Rigging, Time Warping

Mask-Wearing Detection Based on Deep Learning

Advisor: Associate Prof. Yan Xiaodong, Minzu University of China | Jun 2022 – Dec 2022

Studied core concepts of machine learning and deep learning, with hands-on implementations of KNN and K-Means clustering algorithms.
Collected and annotated a dataset of 500 images, then preprocessed the data for model training and evaluation.
Developed a mask detection system using YOLOv2 and ResNet50, achieving 86% accuracy despite challenges of limited dataset size and optimization constraints.
Published findings at the 6th International Conference on Electronic Information Technology and Computer Engineering (EITCE 2022), ACM International Conference Proceedings Series.
