Saeyoung Choi

Product Designer

A product designer leading user-centered service planning and UI/UX design.

I oversee the entire process from UX research and planning to design and development collaboration, aligning business goals with user needs. With a background in web development, I create designs that consider technical feasibility and enhance consistency through design systems.

CORE VALUES

• Leading End-to-End service development and operation (planning–design–development–QA–launch)

• Establishing high-feasibility plans and coordination based on technical understanding

• Designing UI structures with a design system and building reusable components

• Managing schedules and issues through collaboration tools (Git, Jira, Confluence) and documentation

• Bridging communication between technology, design, and operations, leveraging web development experience
