She started her career as a book designer at a design-focused publishing house and now works as a planner building on her foundation in design. As she strived to truly understand her work, she ended up writing her third book and became someone who shares knowledge in front of others. Although she has experienced design and publishing as professional fields, she places more emphasis on design and bookmaking as part of everyday life and general education. Since August 2012, she has been teaching bookmaking classes at Hongdae Sangsangmadang. Her published works include 29 Basic Principles of Good Document Design and InDesign, Editorial Design (co-authored).

Dreaming of the big world, she worked as an expatriate in China. After returning to Korea, she utilized her experience in China to plan and edit foreign books at a publishing house. While creating books, she realized that books are like friends that touch people’s hearts. This sparked her interest in reading therapy and counseling, and she is currently studying counseling.
