I am a product engineer who builds and stabilizes production systems where mobile apps, connected devices, AI agents, and automation meet.
My career started in Flutter multi-platform product engineering and expanded into AX/AI agent engineering. I focus on work that goes beyond 0-to-1 delivery: production rollout, field operations, release automation, monitoring, incident response, and continuous stabilization.
I also work across planning, design, operations, support, and marketing workflows to find team bottlenecks, automate repetitive work, and help products ship reliably with smaller teams.
- AX engineering: Claude Code, Codex CLI, Gemini CLI, OpenClaw, and Multica harnesses with reusable workflows, agents, skills, slash commands, and team templates.
- Product shipping: cross-functional automation for planning, design, operations, support, marketing, release, monitoring, and stabilization.
- AI/RAG products: vector DB, PromptOps, prompt versioning, prompt engineering, MCP, tool calling, LangChain/LangGraph, Gemini, Vertex AI embeddings, semantic routing, SSE streaming, structured output, and evaluation harnesses.
- Flutter product leadership: mobile, desktop, TV, smart glasses, BLE central/peripheral, kiosk mode, OTA, and field device operations.
- Full-stack execution: Next.js, React, FastAPI, Python, PostgreSQL, Redis, Firebase, and GCP Cloud Run.
- Automation systems: Slack/Discord agents, Playwright, uiautomator2, HTTP crawlers, Google Sheets workflows, KakaoTalk operation automation, and SNS lead-generation pipelines.
- AX Engineer at Plaad: building CLI-specific AI harnesses, shared agent/skill workflows, PromptOps/evaluation systems, vector DB/RAG services, MCP/tool-calling flows, data collection pipelines, messenger agents, and operations automation.
- App Lead at XpertINC: led Flutter multi-platform apps for AI smart-glasses products across mobile, desktop, and glasses.
- Project-based Flutter Consultant/App Lead: solved migration, architecture, multi-platform, real-time, and release automation problems across multiple domains.
- Personal AX research: designing Multica-based agentic workflows for plan, design, develop, QA, deploy, and content/PPT automation.
- B.S. track in Game & Mobile Content, Keimyung University.
- Google Cloud Associate Cloud Engineer, earned in 2020.
- Flutter Korea 2022 Google I/O Extended speaker on Dart 3.0 changes.
