Search Engines · AI Agents · LLM Serving · DevOps

I write about systems I build and operate: commerce search engines, hybrid retrieval, MCP agents, LLM serving infrastructure, and the practical decisions behind production AI platforms.

Most long-form posts are currently written in Korean. This English entry page is the first step toward gradual multilingual support, with translated articles added selectively as they are reviewed.

Search

OpenSearch, Qdrant, Korean morphology, hybrid ranking, and search quality evaluation loops.

Agents

MCP tools, graph-based tool retrieval, workflow execution, and human-in-the-loop agent systems.

Infrastructure

LLM serving, Kubernetes, GitOps, GPU operations, and pragmatic production deployment notes.
