ABOUT

I'm Jeongmin, a Product Designer with 10+ years of experience across the U.S. and Korea. I specialize in AI product design, large-scale consumer UX, and system-level interaction models.

At KAYAK, I led the design of the company’s AI assistant and Stays search—building hybrid AI–traditional search flows and aligning LLM outputs with structured travel data.

Previously at NAVER, I redesigned core experiences for 35M+ MAU products, including search, news, translation, and weather. I'm also the author of a published prototyping guidebook and an active evangelist for AI/prototyping workflows.

KAYAK.ai

KAYAK • 2024 - Present

I defined the core concept, IA, visual system, and interaction patterns for KAYAK’s AI-driven search from its earliest stage.

The system was designed to scale across verticals—enabling Flights, Stays, Cars, and Packages to adopt consistent AI behaviors—and ultimately became a foundational component of KAYAK’s company-wide AI roadmap.

KAYAK
Stays

KAYAK • 2023 - 2025

I led the redesign of KAYAK Stays, a complex vertical spanning seven acquired brands, two business models, and multiple legacy card types. I set the UX direction and defined the system changes needed to modernize the experience.

I unified fragmented card formats into one scalable system and redesigned key surfaces like Map, Filters, and Detail. The work improved clarity, reduced engineering overhead, and created a stable foundation for future Stays development.

I led the end-to-end redesign of KAYAK Stays, one of KAYAK’s most complex verticals—spanning seven acquired brands,
two regional business models, and four legacy card types.
Over 18 months, I shaped the product roadmap and drove major UX improvements across the experience.
This included unifying fragmented card formats into a scalable modular system and redesigning key surfaces  such as Map, Filters, and the Detail Page to meet both user and business goals.

NAVER
App / Web

NAVER • 2016 - 2017

I redesigned NAVER’s search and news app across mobile, web, and widget surfaces, improving personalization and discovery for 30M+ monthly users. I defined key interaction patterns, including a new multi-menu editing/navigation model.

This work increased home personalization from 14% → 60% and boosted session engagement. I also introduced rapid prototyping practices that led to the formation of an internal Interaction Design Team and resulted in a published Framer prototyping guidebook.

Papago AI Translate

NAVER • 2020 - 2021

I led the mobile design for Papago, Korea’s leading AI translation service with 20M+ monthly users. I set the product direction for its next-generation experience and defined the early concept and structure for its education-focused features.

I also built the mobile design system, redesigned foundation surfaces, and delivered new iOS widgets used by millions.

NAVER • 2018 - 2019

I led the redesign of WAV, a live-streaming music platform for indie artists with 100K monthly users. My work spanned mobile and desktop, covering UX structure, UI design, and core interaction patterns.

I conducted user research, shaped the product’s experience model, and delivered a unified cross-platform design that improved clarity and usability across the service.
