AI Infrastructure Engineer & Founder — Building the memory layer for AI agents.
I'm a Korean engineer based in Tokyo 🇯🇵 since 2006, currently building Neuradex — a Context as a Service (CaaS) platform that gives AI agents persistent, structured memory.
Before writing code, I wrote music. 🎸 → 💻
Neuradex — Memory infrastructure for AI agents
Context Folding, Stateful Agent Orchestration, Knowledge Graphs — the pieces that make AI agents actually remember and reason across sessions. Built on a Neo4j + Qdrant + PostgreSQL hybrid architecture.
LLM-powered contract review systems at a legal tech startup. RAG pipelines, knowledge graphs, multi-database architectures. Full stack — infra to UI.
I ship with AI. My daily toolkit looks like:
| Layer | Tools |
|---|---|
| Coding | Claude Code (Max), Codex, Cursor |
| AI Infra | LangFuse, OpenRouter, Fireworks AI |
| Core Stack | TypeScript, Next.js, NestJS, Python, FastAPI, PostgreSQL, Neo4j, Qdrant |
| Deploy | AWS, GCP (Cloud Run), Vercel, Cloudflare Workers |
| Docker, Terraform, GitHub Actions |
I once juggled 8 freelance projects simultaneously — that would've been impossible without AI. Now I'm building the infrastructure that makes AI itself work better.
Guitarist → Bassist → Composer → Sound Engineer → Producer → ran a music production company → built a booking system for live shows → one thing led to another → now I'm here, engineering context windows instead of mixing consoles.
