Hi, I'm Seongyeon 👽

Fine Arts × Computer Science · @lalunru

I build at the intersection of logic and creativity — from realtime shaders and VR worlds to explainable AI and design systems.

🚀 What I Ship

  • VR / Game — custom GLSL shaders, URP optimization, multi-ending narrative systems
  • XAI pipelines — IDS with XGBoost + SHAP/LIME explainability on UNSW-NB15
  • Frontend systems — Figma-to-production, design token automation, realtime WebSocket data
  • NPR rendering research — raymarching, edge detection, space-folding in GLSL (Shadertoy + Unity URP)

🛸 Highlighted Work

AssetMind — Financial asset management web service. Tailwind Config ↔ Storybook auto-mapping, realtime order book via WebSocket (STOMP) + React Query.

Line 0 — VR horror adventure for Meta Quest 2. Custom GLSL shaders, baked lightmap migration → stable 72fps.

Beyond the Door of Memory — 2D emotional adventure. Hand-drawn sprites, AI pathfinding chase, multi-ending branch system.

NPR Shaders — Personal research into non-photorealistic rendering in GLSL and Unity URP. Space-folding transforms, raymarching, edge detection — live demos on Shadertoy

XAI Network Intrusion Detection — Graduation thesis. XGBoost IDS on UNSW-NB15 · F1: 0.95 · ROC-AUC: 0.97 · SHAP + LIME explainability.

Malicious URL Classification — LSTM on URL sequences + 9 handcrafted features · 92% accuracy across 4 classes.
