Hi, I'm Jiun 👋🏻
A UI/UX designer who untangles complex systems

3 years of experience designing B2B SaaS products in cybersecurity, turning complex features into something people from any background can understand.
End-to-end experience building design systems, plus shipping websites solo with no-code tools — I like driving cross-team collaboration with clear design docs.
I believe good design comes from understanding your users, your product, and the people you work with.

I like keeping my design files tidy so handoffs go smoothly 😉

💻 UI/UX Design Work

ArgusHack Design System v2 project cover
  • Design System
  • Design Tokens
  • Visual Refresh
  • Component Standardization

As features and data kept growing, the original design spec couldn't keep pace with the product. As the lead designer on this, I rebuilt the token architecture and standardized components and information hierarchy around a “lightweight, clean” principle — resolving the maintenance strain of that growth and making the design easier to extend.

ArgusHack drill scoring feature redesign
  • B2B SaaS
  • Security Product
  • Core Product Feature
  • Design Docs
  • Audience-Tailored Design

ArgusHack is a “security fire drill” platform for enterprises — simulating attacks in your own environment to test how solid your defenses really are. Producing the drill results used to have a steep learning curve, so this redesign rebuilt how results are generated and presented around audience-tailored design, so people from any background can get what they need with ease.

Leukocyte-Lab brand website design and build project cover
  • Web Design
  • Responsive Design
  • No-Code Build

The old site had been improvised from a trade-show landing page, and it struggled to convey the product's positioning or brand image. In a two-week timeline, I turned the given information architecture into a full visual language, spec'd out desktop and mobile layouts, and built and shipped it solo in Framer.

ABMedia fintech news site project cover
  • Web Design
  • Redesign
  • Responsive Design

Overhauled the overall design of this fintech news site and added membership accounts, article bookmarking, likes, and comments — moving past the constraints of the old WordPress setup to build a new, readable site that actually fit the brand.

BESTLA crypto asset management platform project cover
  • UI Design
  • Design System
  • Dark Mode

Iterated on BESTLA, a crypto asset management app — with the feature set left largely unchanged, I rebuilt the design system so the interface reads as cleaner and more consistent, making it easier for users to browse information and manage their holdings.

  • UX Design
  • Craft Workshops
  • Side Project

Built a management system for Little Red Flower Handmade Rugs, a brand running hands-on workshops, so they could organize and manage information more efficiently. The system covers managing students and courses, plus sending emails.

Steam Mobile app redesign project cover
  • User Research
  • PC Gaming Platform
  • Redesign
  • Personal Project

Steam Mobile is Valve's companion app, letting users browse and buy games and chat with friends in the community on their phone. This project redesigned the parts of the interface and flow that felt clunky.
