About Me
AI Engineer — production LLM/RAG systems, 3D game engines, HCI research
Background
I'm an AI Engineer at Redbrick in Seoul, building end-to-end AI pipelines from prototype to production at scale. My work spans production LLM/RAG systems, 3D game engine development, and is grounded in an HCI research foundation.
I specialize in designing agentic workflows, building production RAG pipelines over large document corpora, and creating AI-powered interactive experiences — from natural-language-to-game generation systems to semantic caching layers that cut inference costs and latency.

Experience
AI Engineer
Redbrick, Seoul
- ● Designed and built an end-to-end AI game creation system (intent parsing, asset generation, scene composition, game logic synthesis) — centerpiece of a successful $1.2M government R&D grant
- ● Built production RAG pipelines (LangChain, Vercel AI SDK) over 15K+ documents in ChromaDB with hybrid retrieval, query rewriting, and re-ranking — improving relevance by ~35% and reducing hallucination from 18% to 4%
- ● Implemented multi-step agentic workflows (chain-of-thought, ReACT) orchestrating LLM calls across asset generation, physics config, and script authoring — handling up to 8 dependent tool calls per request
- ● Designed semantic caching layers (embedding similarity-based lookup), reducing redundant LLM calls by ~40%, cutting latency from 3.2s to 0.8s, and saving ~$2K/month in API costs
- ● Owned model evaluation and safety: built prompt regression harnesses, implemented output guardrails (content filtering, structured validation), and enforced policy-compliant generation
3D Frontend Engineer
Redbrick, Seoul
- ● Developed and scaled a browser-based 3D game engine (Three.js, WebGL, TypeScript) powering a platform with 54M+ game plays and 10M+ user sign-ups
- ● Led codebase modernization of 50K+ lines from Webpack to Vite, upgraded Three.js rendering pipeline, replaced physics engine — reducing build times by ~60%, bundles by ~35%, hot-reload from 8s to under 1s
- ● Refactored engine into modular, testable packages to unblock parallel development across 3 teams; wrote integration tests for scene graph and asset loading
- ● Redesigned onboarding flow using session replay analysis and user interviews, increasing 7-day activation by ~25% and Day-30 retention by ~15%
Embedded Systems & HCI Researcher
DECS Lab, UNIST, Ulsan
- ● Wrote IoT firmware in C for ARM Cortex-M MCUs powering real-time smart sensor arrays (50+ devices, sub-ms latency)
- ● Published 6 conference papers, 4 journal articles; co-filed 6 patents. First-author at IEEE RO-MAN 2023, ICROS 2022, HCI Korea 2022

What Drives Me
I'm driven by building AI systems that ship to production — from prototype to scale. Whether it's designing agentic workflows that orchestrate complex multi-step tasks, building RAG pipelines that serve real users, or engineering 3D platforms that reach millions, I believe in combining deep technical craft with human-centered design to create products that genuinely work.
