A writeup of korea-persona-interview, a side project that automates Korean synthetic persona interviews. It layers multi-turn interviews, automatic follow-ups, and persona drift detection on top of NVIDIA’s Nemotron-Personas-Korea dataset to validate business hypotheses quickly. The post also covers the design pattern that lets three entry points (CLI, MCP server, and MCP orchestrator) share a single core.
Before implementing Mollo, an Apple-platform-native agent framework, I summarize the core assets of LangGraph, Koog, OpenAI Agents SDK, Pydantic AI, Mastra, MCP, and Apple frameworks.
A breakdown of the architecture and implementation details behind Yangsiljang, a real estate law and precedent RAG chatbot built as a side project. The frontend was built with Claude Code’s help; the backend was written from scratch. Topics covered include a custom Korean tokenizer build for Milvus, Qwen3 embedding/reranker, HyDE, SSE streaming, and data ingestion from the Korean Legislative Service.
