It’s been a while since I wrote the news that I joined Stokke to be one of the starting members for the innovation hub in Shanghai. We started the R&D tech lab to make IoT products for babies by adapting Stokke products. It was quite big challenging for every one in the company since we’re all new to this kind of edge technology for the baby care products.
We aimed to launch a product in a new category that no one ever had succeeded in it. Due to the high risk of opening new product category for the market, it was not easy to get the safety certificate guaranteed by a safety certification company since they even didn’t know how to do the test to guarantee the safety. Thus we couldn’t launch our products at the moment even though we’ve tried so hard to make those. More over, that year there was an accident and the huge recall made by Fisher-Price due to the product safety failed.
While we were struggle on it, the Corona virus came up all over the world this year, started from China. In addition to that, Stokke also made a decision to shutdown the innovation hub in Shanghai… Accordingly, I had to come back to Korea early of this year for the various of reasons.
Korea’s First Bitcoin Exchange, Korbit!
About a month ago, I got an opportunity to work with a company named Korbit doing Bitcoin exchange business in Korea. Korbit is one of the big four companies in Korea in the field of Bitcoin exchange. They have more than 20 cryptocurrencies published right now supporting the trading in Korean Won. Korbit was founded by Tony Lyu in 2013 and got invested by several parties in the early days including SoftBank Ventures and PANTERA Capital. It’s acquired by NXC afterwards which is well-known as the game company, NEXON, in Korea.
I joined this company recently to be in charge of the mobile app of Korbit and to lead the development team for the app. It’s a new challenge for me again since this is also new area for me while we’re facing lots of difficulties in the business, especially in Korea due to the new upcoming regulatory for the cryptocurrency. Despite of all the difficulties, I’m quite exiting to be part of the journey and want to be succeeded in this challenge.
We’re all facing difficult situations right now due to the virus. Let’s keep working on it step by step. Please take care of yourself first. Thank you.
After I finished my study in KAIST last year, I had to decide my next career like all the colleague students. I could take a rest for a while or have a break to continue my study again. There were plenty of ways I could choose, I believe. Nothing was easy to decide… and one of them was obviously becoming the indie game developer for few years. It could be good opportunity actually- after all my journey in office life.
Well.. as a result, I decided to join Stokke in Shanghai, China. To be honest, it was quite big decision for me living in Korea. Stokke is the company selling baby products which means I needed to change my career from the game developer to software engineer, and of course I had to move to Shanghai where I’ve never lived before abroad. It was tough decision indeed.. however, I saw lots of opportunities here, so I decided to join Stokke. Now I’m living in Shanghai, and the start member of Tech Lab of Stokke in China.
Stokke is a company well-known as Trip Trapp, its premium strollers and high chairs with other baby products such as baby carriers or home furniture for baby. Its heritage comes from Norway, and Stokke is the one of companies representing Scandinavian design delicately in the world.
… “Founded on the west coast of Norway, over eighty years ago, Stokke® began life as a manufacturer of high quality Scandinavian furniture. Since launching the revolutionary Tripp Trapp® chair in 1972, we have evolved into a company that focuses exclusively on premium design for children. Today, we are recognized for timeless Scandinavian design that brings you and your child closer.” … from “A History of Innovation” of about Stokke in stoke.com
There are already a lot of IoT products out there even for baby products in the market. So, it might be natural Stokke decided to have its own R&D center at this moment. Especially in Shanghai, it’s very easy to find experienced co-operative partners and suppliers for our products. Shanghai is the one of biggest well-developed industrial cities which have an excellent IT and financial infrastructure for co-operations. We don’t have only partners here but also plenty of potential customers who are already very used to using IoT products.
I‘m in charge of designing and developing software here. All the IoT products need its own specific firmware embedded inside MCU of microcontroller board, and it also needs an application to control itself. I develop and manage all the software by myself for our project, and try to find the best hardware and platform for us. Luckily, we have lots of partners who can help us to develop and support our project in Shanghai already, so it’s very fascinating to be a software engineer here focusing into more creative stuff.
Our mission here is researching and developing creative and challenging products for baby to make people closer to their adorable babies. I believe our team can make better world while our products keep its natural characters based on Scandinavian design. For Stokke, it’s very important to keep this indeed, and to be honest, I’m surprised that we have lots of benefits when we have nature friendly and human-centered design for baby product in daily life. It’s not only good for parents but also your babies.
I hope one day we get a design award in Baby Tech which is the biggest contest in baby industry of CES Las Vegas.

Last spring semester, I developed a SNS application called PICKME! for indecisiveness with my teammates as a project in the class of KAIST CS408 Computer Science Project. This project aimed to help people who want to resolve their indecisive issues by asking to massive users who experienced similar issues or just asking their opinions via votes or comments.
“How can we resolve their issues effectively?”
Our goal was the developing a mobile service application for end users and recommender system to recommend personalized contents so that users can easily find their similar or interested issues and resolve their indecisive issues which they might be interested.
Key Features
1) Post a card that user want to share to resolve his/her issue
2) Participate vote to share his/her opinions
3) Communicate via comments to share his/her thought
4) Explorer and get recommended contents from recommender system
We used Unity for a client application for Android and iOS platforms, and Firebase and Django for database and server networking. We also extracted and analyzed 15,000+ tweets to test our recommender system based on collaborative filtering with LDA topics. To measure our project, we did a survey to KAIST members with the mobile application as a beta testing.

A few years ago, I established my own company, MindPol. We developed several games for mobile platform with our own game engine technology. I ran my company for about 3 years and 6 months. Today, I’m going to tell you some memorable moments of MindPol.
MindPol and Galatea Engine 2007-2010
The company MindPol was started with technology on game engine at first. The Galatea Engine, a name of our engine, supported rendering 3D models with software skinned animations, massive particle systems with editor, various texture formats with tool, useful user interface classes, and also rendering fonts for Hangul character system. Furthermore, Galatea Engine was designed to support portable platforms including PC at first. It supported experimentally Nintendo DS platform too with specialized features such as Fixed-Point data type or rendering 3D models in cartoon style.
We also developed a game called The Flower And The Wind (꽃과 바람) to introduce our technique. It was a arcade game with adorable action characters in 3D graphics. We demonstrated our engine skills effectively with it even if we couldn’t publish the game to the end.
Now we have a couple of great game engines, however it was way different back then. There were tons of game engines, and lots of solutions had their own specilized features with own philosophy. Since we focused on mobile platforms like Windows Mobile or Android early, we could have a chance to make our own business.
We also participated in G-TEK 2009, Global Technology Exhibition in Korea, and demonstrated our engine with mobile 3D graphics running smoothly on Sony Ericsson Xperia X1 device. It was quite impressive at that time because Xperia X1 was a device accelerated 3D graphics officially with very first GPU chip by Qualcomm. We’ve got attentions from XDA forum and companies who want to cooperate and share our experiences on mobile platforms.

Now, let’s talk about games after we developed a game engine.
2009-2010 10 Games for Betting (Windows Mobile, iPhone)
10 Games for Betting was a collection of tiny betting games. It was very fun and light to enjoy. Lots of people downloaded and enjoyed it from various market. We estimate there were more than 200,000 downloads altogether. Actually, it achieved quite good because there weren’t plenty of games on Windows Mobile at that time. This game was awarded a bronze prize too in Samsung Application Store Developer Challenge 2009.

2009-2010 Run Kattie (Windows Mobile, iPhone)
Run Kattie was a casual 3D game that a cat is a hero jumping between buildings and avoiding obstacles on the roof. People loved the cat character because she was so cute and adorable. There were 3 amazing maps with theme songs, and various items to play fun.
Playing Run Kattie for iOS (Apple iPhone)
Playing Run Kattie on HTC HD2 (Windows Mobile)
After we released Run Kattie, we thought now it’s time for heading towards new platform, iPhone market. With a little work on our engine code, we could simply make our products run on iPhone platform.
2010 Sweety Ball – Fairy Tale Edition (iOS, iPhone)
Sweety Ball – Fairy Tale Edition was a kind of snow ball toy. It was an entertainment app designed for everyone. There were 3 themes with songs, and also was a feature for creating customized theme with a user message and picture. People loved this tiny interactive snow ball app.

2010 Sys-Cake – Shut Da Mouth (iOS, iPhone)
The Sys-Cake was a very special project of our work. It was so experimental, and we wanted to make something unique with electronic music. We contacted a few musicians, and we could have a chance to collaborate with Shut Da Mouth, one of great DJ duos with DJ Beejay. It was so great opportunity to us actually. We enjoyed working on this project, and we could release Sys-Cake – Shut Da Mouth proudly. It was a collaborated DJ app with awesome club music. You could make and play your own club music with this tiny DJ app on Shut Da Mouth style. It was really fun there! Wherever you go with it, you could make it club style!

2010 House Rulez – Magic Television (iOS, iPhone)
After Sys-Cake project, we wanted to continue developing music app more. We this time decided to develop music album app with musicians. House Rulez was one of impressive musicians in groove and house music. Their music style was so special and unique. We fortunately could have a chance to meet them to discuss our next project. It was so great since we had a great idea for music application on mobile platform. We finally published House Rulez – Magic Television which had entire songs of their 3th album, lyrics, and also a special hidden song. It was very special because extra song was only provided with our app. We also provided lots of animations in the style of album jacket.
House Rulez – Magic Television (3th Album) for iOS
Remember the mind for precious our life..
Over a long term of years, MindPol developed various games and apps on mobile platforms. We can’t say that our business was successful, however it was priceless time. I was young, and guts and passion were the only things I had. No matter how much I spent my time, it’s a valuable experience which I don’t want to exchange forever. We had lots of partners at that time including big firms such as Microsoft or Samsung. I hope MindPol contributes a little bit to mobile industry. Thank you for reading my old memories.
Here’s the list of all products and platforms of MindPol.
2010 Techno Bone Galaxy Tab (Android, Galaxy Tab)
2010 House Rulez – Magic Television (iOS, iPhone)
2010 Sys-Cake – Shut Da Mouth (iOS, iPhone)
2010 Sweety Ball – Fairy Tale Edition (iOS, iPhone)
It seems like forever since I last updated my news here. First of all, I resigned from last work almost six months ago. I finished my duty as military service, and I went back to school from this Fall semester to finish my bachelor’s degree. It’s been a really long time because I was on break from school for seven whole years. This is so challenging. I have to attend school for two more years, jeez. I already miss my friends that I was working with.
I haven’t decided yet, now I am thinking of the job as an indie game developer or just application developer. I know it’s not easy; taking classes with working at same time. The point is that I will keep creating programming work to maximize my development skills. To my great joy, there are a lot of great students in my school, KAIST. It is one of the great school in Korea, and I am so looking forward to working with them when I get a chance soon.
To sum up, eight years ago I operated my own company MindPol for more than three years, I was one of founder mentors from SW Maestro in 2010, I worked for NXC, which is a holding company of Nexon, as a team manager from app. development center for one and a half years, I also worked for ESTsoft as a mobile game developer for three years, and now I’m back to my school finally! It’s been a long road, and I believe I will just keep going as long as I can.
So, keep in touch with my website and I hope you enjoy the end of this year! 🙂

Let’s talk about the programming part. After we have developed Boom Boom Power, I started to develop Crash Girls for next step. I decided to use Unity for following project, so it became my first official project developed with Unity. Unity is the powerful and effective 3d game engine of Unity Technologies. For more details, visit www.unity3d.com.
In my team, we mainly used to develop games with cocos2d-x. But we needed to develop our following game with Unity for future project. We wanted to support various devices and platforms easily and also make development process good to teamwork. Unity had already everything we want, so we decided to change our development environment to Unity even if the first project needed only 2d features.
Now, the game is begun. We invite you to global ranking of Crash Girls. Invite your facebook friends and fight for the highest world ranker!
Hello everyone! How do you do in the end of this summer? Nowdays I’m working hard on new project and I think it’s the time to recall our previous project, Boom Boom Power, from ESTsoft.
With several months, we’ve released a series of this game, Boom Boom Power for Kakao and Boom Boom Power Worldwide. Boom Boom Power is the original title that the cutest pig, Popo, runs with his glorious friends to avoid and defeat evil enemies. It’s a casual arcade game and you can play/enjoy it easily.
As we introduced before, our game was designed to play with your friends connected to Facebook account. You can invite them to run together and also compete with them on game score. After we released it first, we could get a chance to publish on Kakao platform for Korean users with these all good features. It was good opportunity for all of us, and it still helps its downloads increasing by people who want to play our game with their close friends.
At the same time, we’re also interested in each components of whole game systems. We called it Reboot Project. Re-designing items and skills, removing/adding new heroes and themes, and keeping everything in the balance. Developing major updates was not an easy decision, but we finished it successfully with hard work. I think it’s worth it.
After we released for Kakao, we faced the time to translate it in english and expand user experiences with people playing our game around the world together. We thought it might be more fun if they can play with more friends even if they don’t know. So we decided to develop new ranking systems with random global friends and highest top 10s of the world ranking. And further more, your own global friends will be changed everyday!
Ok, so here we are. It’s all about our efforts to make better experiences with Boom Boom Power. I hope it would be a little gift to people enjoying our friendly game. Touch the top of the world ranking, Boom Boom!
Today, I’m very excited to announce that we finally released our latest project, Boom Boom Power! We’ve been working so hard for so long! I’m very glad that we eventually made it. Yeah!
This, Boom Boom Power, is the second mobile game project of ESTsoft. It’s a casual racing game with the cutest animal characters. All the characters, objects and themes are so cute and very unique. And the game play of Boom Boom Power is so simple that everyone can play and enjoy it easily. Move your hero, avoid evil enemies, and score your ranking.
