Design (D.WELL interaction prototype) at D.WELL (gyuholeee.com)

June 1, 2026 - Present

Developed a hardware-independent interaction concept for reflective confirmation tapping. Created D.WELL as a tangible commit control: a hold placed in front of confirmation that grows when user behavior indicates abort patterns. Built the core in C/C++ with an AI coding assistant, used unit tests with CSV logging, and validated the button-to-log loop on a simulated Arduino board.

Interaction Designer (D WELL prototype) at D WELL

June 1, 2026 - Present

Designed a tangible interaction concept for high-stakes confirmations where users tap reflectively. Implemented a 'hold' control that requires deliberate action and grows the hold duration when behavior indicates repeated aborting patterns. Built a hardware-independent core in C/C++ with an AI coding assistant, including 20/20 unit tests and CSV logging, and validated the button-to-log loop on a simulated Arduino setup.

Interaction prototype designer (D WELL) at D WELL

June 1, 2026 - Present

Built a hardware-independent interaction prototype where high-stakes confirmations require a reflexive hold rather than a tap. The hold grows when recent behavior suggests abort patterns. Developed the core in C/C++ with an AI coding assistant, including unit tests and CSV logging, and verified the full button-to-log loop on a simulated Arduino board.

Product Designer & Research at Fixie AI

December 1, 2025 - February 28, 2026

UX research and product design supporting human–AI interaction. Interviewed 14 people (7 in depth) across both sides of equipment repair. Reframed the core issue: not speed, but the silence after reporting—designing a communication layer instead of matching. Rebuilt job indexing around job codes to avoid breakage when juggling multiple jobs, and validated reduction in time to first estimate to under 30 minutes; also reduced mockup time (3–4 weeks to ~1.5 weeks).

Product Designer & Researcher (Fixie AI) at Fixie AI

December 1, 2025 - February 1, 2026

Conducted UX research and evaluation focused on human-AI interaction and physical-digital repair workflows. Interviewed 14 people (7 deep in-depth) across both sides of equipment repair; identified that the key problem was not speed, but the silence after the report. Designed a communication layer solution and restructured technician job mapping around job codes to handle multi-job load. In directional testing with 7 technicians, reduced time to first estimate from 11–14 days to under 30 minutes. Used AI-assisted exploration to reduce personal mockup time from 3–4 weeks to ~1.5 weeks.

Conducted UX research and evaluation across human–AI interaction and physical-digital workflows. Interviewed 14 people (7 in depth) across both sides of equipment repair; the core problem was silence after reports rather than speed. Designed a communication layer that maps technician job lists by job codes to reduce context switching. Directional testing with 7 technicians reduced time to first estimate from 11–14 days to under 30 minutes, and AI-assisted exploration reduced prototyping time from 3–4 weeks to ~1.5 weeks.

Identified that the core problem was not speed, but the silence after the report; designed a communication layer instead of a matching system. Reframed AI outputs around job codes to prevent breakdowns caused by technician indexing by customer name. Validated directionally with 7 technicians, reducing time to first estimate from 11–14 days to under 30 minutes. Also reduced own mockup time from 3–4 weeks to ~1.5 weeks through AI-assisted exploration.

Product & Interaction Designer (Independent Design Practice) at Independent design practice

August 1, 2025 - Present

Independent design practice focused on starting from an interaction hypothesis and ending with testable outputs. Conducts UX research, usability testing, information architecture work, and designs mobile-first, responsive digital experiences and systems.

Product & Interaction Designer (Sole Designer) at Independent design practice, Berlin

August 1, 2025 - Present

Led end-to-end responsive web design, digital storefront layouts, and visual touchpoints from concept to launch. Improved information architecture to increase search success (65% to 92%) by restructuring product-detail hierarchy based on usability testing with 37 users. Scoped MVP based on findings that drop-off happened at first-time setup; aligned founder and developer on removing secondary features to prioritize onboarding, shipping on the original date. Reduced support queries by 28% by redesigning physical-to-digital onboarding flow to mirror the printed manual’s step sequence. Built a scalable design system and AI-assisted workflow for multiple product lines and popup events by creating reusable components and generating transcript synthesis and copy variants, enabling one designer to cover high volume.

Independent design practice (Product & Interaction Designer)

August 1, 2025 - Present

Runs an independent practice in Berlin, starting each engagement from an interaction hypothesis and ending with something testable through research and iterative design.

Sole Product & Interaction Designer (Freelance/Independent) at Independent design practice

August 1, 2025 - Present

Led end-to-end responsive web design and visual touchpoints from concept to launch. Improved information architecture and conversion by restructuring product-detail hierarchy based on buyer behavior; increased search success from 65% to 92% (user testing with 37 people). Used testing insights to identify first-time setup as the main drop-off point, enabling v1 scope cuts (removed secondary features) and focusing on onboarding; shipped on the original date. Rebuilt physical-to-digital onboarding to match the physical manual sequence, reducing support inquiries by 28% within three months. Built a scalable design system for multiple product lines and six pop-up events, using AI workflows (transcript synthesis and copy variants) to increase output and consistency, enabling one designer to manage high volume.

Sole designer delivering end-to-end responsive web design and digital storefront layout from concept to launch. Rebuilt product-detail information architecture after usability testing (37 users), improving search success from 65% to 92% by reorganizing around what buyers check first. Identified MVP drop-off at first-time setup (not browsing), helping the founder and developer cut secondary features from v1 and focus on onboarding; shipped on the original date. Reduced support inquiries by 28% in three months by redesigning physical-to-digital onboarding to mirror the printed manual step-by-step. Created a scalable design system and AI workflow across multiple product lines and events by building reusable components and using LLMs for transcript synthesis and copy variants, enabling one designer to cover high volume.
