Jinju Park · UX Engineer / Product Designer
Portfolio / Alt. 02
I turn dense systems into interfaces with a pulse.
01 / Selected work
Six difficult systems.
Six clearer ways through.
Open a project and follow the full story—context, decisions, system, and impact.
02 / How I work
Clarity is not a style.
It is a sequence.
I stay close enough to the problem to carry intent from the first question into the shipped behavior.
Trace reality
Map user friction, business intent, technical constraints, and the quiet failures hiding between teams.
- Research
- Audits
- Friction maps
Build the system
Turn findings into architecture: flows, states, tokens, components, and rules that can survive scale.
- IA
- Prototypes
- Design systems
Ship the behavior
Work in the code, close design gaps, test edge cases, and protect the idea through production.
- Front-end
- QA
- Iteration
Interlude / Motion study
Fragmentsfind a system.
An abstract motion study turns a constellation of glass interface fragments into a precise modular grid, then releases it back into motion.
Interactive principle / 00—100
Turn the mess into
a working system.
Drag the signal. The same inputs remain—the relationships become useful.
The useful overlap
Designer enough to question the system.
Engineer enough to change it.
03 / About
I work where handoff usually breaks.
I’m Jinju, a UX engineer and product designer who turns ambiguity into systems people can use—and teams can actually build.
My range spans AI products, financial data, global entertainment, mobile archives, enterprise publishing, and cross-cultural platforms. The thread is always the same: understand the real constraint, make the structure visible, and ship with care.
Research synthesis, product framing, information architecture, interaction models, and high-fidelity prototyping.
Design tokens, component architecture, multilingual typography, governance, documentation, and QA frameworks.
Semantic HTML, modern CSS, JavaScript, TypeScript, D3, responsive behavior, accessibility, and CMS architecture.
