Useful systems.
Honest signals.
I’m Moohwaan, a practical data builder turning messy real-world problems into clear tools, repeatable workflows, and decision-ready evidence.
Selected work
Built around
real constraints.
Projects where data quality, clarity, and operational usefulness matter as much as the final interface.
Data & Dashboards
Steel Price Dashboard
A source-backed monitoring workspace that turns fragmented steel-price updates into decision-ready signals.
Trading Research
XAUUSD Morning Analysis System
A repeatable pre-market workflow for turning macro context, venue status, and risk signals into an actionable brief.
Automation & AI
Personal Knowledge & AI Retrieval
A practical knowledge system that makes notes searchable, traceable, and useful inside everyday AI-assisted work.
Operating principles
Trace the source.
Important outputs should point back to the evidence and definitions that produced them.
Design for uncertainty.
Missing, stale, and conflicting data are system states—not details to hide.
Leave a clear next step.
A useful workflow makes it easy for someone to understand where things stand and continue the work.
Field notes
Thinking in public.
A dashboard is only as useful as its source trail
Why freshness, provenance, and failure states belong in the interface—not only in the pipeline logs.
Automation should admit what it does not know
A short design principle for research workflows that operate with incomplete or stale evidence.
