Learning
Building data fluency
Practicing SQL and Python with small examples, clean notes, and repeatable analysis habits.
Personal editorial hub
Yaehun Lee
I document how I learn data, build useful web projects, cook Korean food in Dublin, and turn music sketches into a clearer creative practice.
Now
What I'm focused on now
The homepage is organized around the work that is active, not only finished. These are the threads I want visitors to understand first.
Building
Turning study into artifacts
Using this site as the first product: clear routes, better content systems, and useful project writeups.
Cooking
Korean food in Dublin
Testing recipes around local groceries, ingredient swaps, and dishes worth repeating.
Creating
Music sketches with feeling
Collecting Logic Pro loops, mood notes, and unfinished ideas before they become full tracks.
Sections
Choose a route by purpose
Each category has its own content pattern so the site feels like a personal hub, not a set of identical link cards.

Work that explains the direction
These are framed as project summaries, not just links. Each one shows the problem, current status, and why it matters.
In progress 01
Personal Hub Redesign
Rebuilding the site architecture so data, projects, food, music, and notes each have a distinct experience.
- Problem: the old site looked different but still behaved like a basic link list.
- Tools: Astro, Tailwind, lightweight i18n
Learning track 02
SQL Practice Archive
A growing record of query patterns, joins, grouping, and small exercises that make progress visible.
- Problem: practice disappears unless it is documented in reusable examples.
- Tools: SQL, Python, notes
Experiment log 03
Korean Food in Dublin
A cooking record for Korean dishes shaped by local ingredients, substitutions, and repeatable recipes.
- Problem: good cooking decisions are easy to forget after the meal is gone.
- Tools: recipe notes, photos, ingredient tests
