AI Engineer — I build, evaluate, and maintain AI services. Neuroscience × Computer Science (Korea University) → AI services, backend APIs, retrieval, and agent tools. Project pages distinguish internal use, client installations, public prototypes, and controlled experiments.

| Project | What it is | Stack |
|---|---|---|
| med-rag (private client installation) | Local RAG installed on a Korea University Anam Hospital professor’s personal PC in October 2025, with ongoing remote updates. Public examples use synthetic data · case study | Gemma 3 27B / Ollama · LangChain · Chroma |
| agent-orchestra | LangGraph orchestration reference with parallel researchers, revision loops, and procedural memory. Offline checks validate the control flow; message envelopes do not establish A2A protocol interoperability | LangGraph · LangSmith · Claude API |
| med-rag-vertex | Separate synthetic-data experiment: ADK SequentialAgent (researcher → reviewer) with retrieval and evidence-aware answer evaluation |
Vertex AI · Gemini 2.5 · ADK |
| terracotta | Personal AI workspace with provider routing, MCP tools, approval state, execution traces, and cost records. Routing benchmarks are offline policy simulations, not measured model-quality gains. Workspace extensions are in draft PR #1 | TypeScript · Cloudflare Workers · D1 |
| legal-pdf-rag-chatbot | Streamlit RAG on main. Draft PR #8 adds FastAPI, tenant-scoped storage and CI checks; production identity integration and live cloud deployment remain unverified | FastAPI · SQLite · Chroma · ADK |
| higgsMCP | AI beauty influencer automation — character-consistent content generation to Instagram publishing via MCP | FastAPI · Higgsfield MCP · Docker |
-
Meeting Assistant — internal FastAPI service connecting audio processing, structured minutes, Notion and email; job status, partial-result retention and retry support. I own development and operations. Public pages contain sample data.
-
app-automation-gpt — Node.js/Express development agent with Google identity validation, account-scoped APIs, encrypted credentials, cancellation/retry and conditional state updates. Tests isolate external providers; live cloud operation is a separate validation step.
-
AI PPT Studio — brand design systems → editable PPTX export, Claude-powered deck generation
-
TableON — restaurant product UI demo with sample CRM, payroll and reservation workflows; the public demo simulates its API
-
Mobile apps — mental-care & breakup-recovery apps (planned/designed/built solo, Capacitor iOS/Android) · try the live emulators
-
Walk-Mate — themed Seoul walking courses on a tilted 3D map (Expo · MapLibre GL)
-
…and more in the full portfolio — selected projects with source links and explicit implementation and validation scope
