You have 15 years of design experience. If you divide this long period of time into different phases, how would you do? Can you describe it in details?
当我快30岁时，我拿到了创业公司的offer，加入了一个叫做“rocket internet”的德国国际公司，三年时间里都作为亚太地区的负责人，并推出了许多创新产品。一直到四年前，我加入了cashslide(NBT) 。
First of all, I didn't graduate from the Design department, but I graduated from the accounting department in the university. People get shocked every time I talk about my major.
"Fusion" is still so popular in Korea that I have not regretted it since more than 3 years after entering the design industry, I gained more benefits than my friends who came to design department.
For the frist 3 years I taught design. I taught design theory and computer graphics (photoshop, illustration, flash, etc.) at school.
After that, I was mainly working on the website, commercial design and promotion in the design agency. When I was 25 years old, I was promoted to leader of the design team and mainly worked on making a design proposal for the big companies.
When I'm turning 30 years old, I got offered from start-up company and joined the german international company called "rocket internet (https://www.rocket-internet.com/)" as a head of design for Asia pacific region for 3 years and launched many start-up products. Then, I have joined cashslide(NBT) 4 years ago.
Cashslide’s users encompass 1/5th of domestic population. With such a large customer base including various ages, background, culture, etc, what is the most important thing to consider in design?
In designing "popular", it's essential to provide a sense of confidence and stability.
If you are loosing a balance to one side, others might feel uncomfortable in your work. So I try to balance it to not become too heavy or light even when I make a change or modifications of my work, I implemented it as little as possible to make users will be able to adapt it slowly.
As a designer, how do you gain insight into the trend?
One of my favorite hobby is reading. It's one of the best way to discover the trend through reading many books that related to design and liberal arts. Because, you need to think about how to understand and accept the truth and facts from the books. Also, I traveled many cities, especially Tokyo, and visit the exhibitions and
when I have the chance.
Since you believe that good design cannot be judged only by its rightness, how do you balance the rationality and sensibility in design?
I believe that product contains two main factors. In fact, it's applied in even design and functionality as well. The truth is, it's hard to think separately between the functionality and external appearance. They can't stand alone by itself. It means that a function is not defined as 'added value' in design, or it is not established as a separate aesthetic.
That's why design is the essence of the product, and I would suggest that the designers should not think about it separately.
Cashslide Calendar is inspired by the form of the Korean traditional furniture of "dressing mirror stands" motif. What other traditional elements do you usually employ in your design?
我有许多项目中用到了传统元素，比如“Cheongsam Lantern （用来照亮道路）”和“Hairpin （女性用来固定头发的饰品）”，它们都入围了首尔城市品牌这个比赛，有在电视上播出。
Well, there are too many Korean traditional elements can be adopted in the design. Among them, Hanbok (traditional custom), Tile roof, Roofing lanterns, Hangul (Korean letter) is somehow the commonly used elements.
There were cases where I made my work using traditional elements "Cheongsam Lantern (used to bright the road)" and "Hairpin (women's ornaments that are inserted to fix the hair) awarded as a finalist of Seoul City Branding which was the contest held on TV.
You have ever worked in many start-up companies. What is the difference between start-up company and mature company in your opinion?
Start-up company is normally fast paced environment in terms of making a decision, shift to the new things, initiative and challenging work as well. This means that people have more chance to have in-death responsible for your work and achieve huge accomplishment if a person is willing take a challenge. But it's not suitable for a person who is seeking for the stability.
In addition, the role of the design leadership in the start-up company is very important. Not just build up the process, design management, or CEO's understanding of design, the role and result of the design can be totally different depend on the capabilities of designer's leadership on start-up environment.
In recent years, you have won various awards. How do you think of competition?
I have never thought of anything special, but I would like to win a Gold Prize at IF or Reddot in the near future.
I want to make such a work soon.
