AI / Knowledge Platform
Designed and implemented RAG pipelines, MCP proxies, and AI agents with extreme cost/memory optimization.
Engineer who hardens the foundation from platforms to realtime servers
About
Ship new services fast while architecting a solid core and proving quality with data.
I have built realtime game servers, backend platforms, fintech trading systems, blockchain services, and AI RAG pipelines. I pick the right stack for each problem—C++/C#, Kotlin/Spring, TypeScript/NestJS, Python/FastAPI—without hesitating to learn new layers.
Large-scale traffic and high-stake services shaped my bar for stability. I operated products that handle 22 billion KRW AUM, delivered a patent-pending MCP proxy, and launched a 1Gi memory knowledge search service that users rely on.
I care about how teams grow together. Code reviews, documentation, and automated tests make quality shareable, and public talks or OSS work feed the community back.
