Focused on AI learning services and Korean NLP, working from Seoul, South Korea.
I specialize in planning AI-powered learning services for Korean education — turning vague ideas into problem data, feature specs, and working prototypes. I'm passionate about building software that makes a difference.
Beyond my work as an AI service planner at Keduall, I build tools like TextViz, OutlineForge, Promptlog, and FunCommute — combining product planning with hands-on AI engineering.
Trained as a Korean linguistics scholar with a Hallyu software double major, I treat Korean as both language and research material — building NLP datasets, annotation standards, and education services around it.
I'm currently working on some exciting projects that I can't wait to share with you. But I'm always open to new opportunities and collaborations.
PRD, IA, UI/UX Documentation, MVP Scoping, Feature Specifications, User Flows, User Research, Interview Design, Waitlist Landing Planning.
Prompt Engineering, LLM Evaluation, RAG, Multi-Agent Systems, OCR Pipelines, Data Augmentation, Question Generation, Golden Set Construction, Python.
Education & Language Domain, Korean NLP, TypeScript, Next.js, Tauri, Figma, Cursor, Claude Code, Git/GitHub.
Always exploring new tools, models, and ways to turn scattered ideas into working products :)
From AI learning services to developer tools — every project here connects planning, data, and working prototypes.
I love turning complex thoughts into practical tools — from planning documents and diagrams to prompt libraries and reports.
Tools I've built include TextViz, OutlineForge, Promptlog, DeckForge, and FunCommute.
The beliefs that shape how I plan, build data, and ship products
The human is the bottleneck. The best technology multiplies what people can do — it doesn't just replace them. Every tool I build is aimed at widening what one person can carry.
Why I build tools
Define the problem precisely before reaching for a tool. I like finding the connections between data — what evidence is needed, and what criteria will judge the result — before anything gets built.
Before the tool
Turn vague requirements into screens, data, and workflows. Documents alone don't ship products — I deliver HTML wireframes and working prototypes that developers can actually see and run.
Ideas into artifacts
Judge results against a golden set, not against taste. From resume data to generated TOPIK questions, evaluation criteria are what turn opinions into decisions and iterations into progress.
Evidence over taste
Touch new technology first. Possibility and limits only become real when you build with it — I prototype with the newest models and frameworks, then check whether they survive real cost and market conditions.
New tech, verified
Vertical domain knowledge wins. In AI, the difference is made by deep domain expertise — for me, Korean education and NLP — combined with the speed to verify ideas end to end.
