Daily 3D voxel puzzle game (Wordle-style cadence). Solo programming on a team with designers and 3D artists; built full game stack: Rust/WASM puzzle engine, DSL, Three.js renderer, leaderboards, daily puzzle flow, token/reward system, and cosmetic shop.

Software Engineer at Earth Shine Co., Ltd.

February 1, 2023 - February 1, 2026

Designed and implemented a node-based shader editor end-to-end — first in C++ on O3DE (Atom renderer, Ly Shine UI, core engine, Gem plugin system), then ported to React + TypeScript + Vite + Three.js. Supported runtime hot-reload of new node types, per-node sub-preview, and customizable serialization; outputs GLSL/WGSL/GLSL. Built for customer release. Led full-stack AI feature work (image-generation and 3D-generation) from frontend UX to backend inference endpoints using Rust. Implemented a production Rust AI agent architecture (backend, AWS, RunPod) and established company-wide LLM tooling and RAG workflows (Discord-native agent using LangGraph/LangChain, Gemini/Groq/OpenAI, ComfyUI). Led selected projects: Daily Cube (2025–2026 launch), Encoded War (Steam 2022–2023), and DucklingEngine ecosystem.
