My Journey – From Engineer To Designer
Engineer who loved drawing, typography and user interface
I always loved drawing things, especially letters and logotypes. My textbooks were filled with cartoon characters and company logo sketches. When I was working as a software engineer, I loved working on the user interface with beautiful typefaces - even though it was before the smartphone era and the screen resolution was 176x220. I enjoyed customizing my code editor with Helvetica and gorgeous modern fonts. Even though I loved working on software for the great products, I wanted to work on something visual that can be seen by people, interact directly with people, instead of the logic hidden in the shell.

Design school, graphic design and mobile Apps
With my passion for design, I made a big decision to go back to school to study design. When I was quitting my job, I thought I won’t code again. However, I learned that technology could be a great tool to realize my design idea and vision. I saw how evolving technologies were starting to empower art & design in various areas such as media art and data visualization.

The new era of mobile and apps opened new opportunities for the designers and developers to share the idea with people around the world. It looked so fun, I really enjoyed learning new language Objective-C and development tool Xcode.

Starting with simple clock app HUE Clock, I have designed & developed various types of apps such as experimental twitter client Twit Knoll or GPS tracking app Daily Traces. With my strong interest in editorial design, I proposed, designed and developed brochure app for Parsons School of Design. With the support of dean of Parsons, it became the official app of Parsons.

Writing iPhone programming book to share my 'Developer Experience'
After launching several personal apps, I wanted to share my ‘Developer Experience’ with people. Even though most of the people focused on the UX for iPhone's success, I thought great DX(Developer eXperience) was also a crucial part of its success. It was a unique, not like traditional software development. I could see the result quickly, GUI based user interface design was a fun process. My strong interest in editorial & information design was a big motivation for writing this book. I also did all editorial design with InDesign by myself.

Typography Insight
With my strong passion for typography, mobile app and user experience, I have designed and developed Typography Insight as my MFA thesis project. Fortunately, I got a chance to present this project at AIGA/NY. It was featured by Fast Company, The Atlantic, and Gizmodo. It was ranked 2nd in the education category of US App Store in 2011 and featured several times on App Store in various countries.

Continuing my journey as a designer at Microsoft
Designing MSN apps for Windows
Luckily enough, I was able to continue working on apps at Microsoft. I started working at Microsoft as the main designer for Sports and Finance app (Bing AppEx App Experience Team). Both apps had a rich amount of data - stats, numbers, and images - to play with, it was almost like designing magazines. Fortunately, it was also the moment when Microsoft's new metro design language started to bloom. I really enjoyed designing apps with fundamental graphic design elements - typography and grid.

Also as a designer who has a developer background, I was able to convince the dev team to allow us checking out/in the code for the frontend. After finishing design, I worked on design integration to achieve the pixel perfect design and fit & finish. I really enjoyed sitting together with developers and having discussions about the technologies that can achieve great UX.

Continuing personal projects – Typography Insight, Survi Birds
I kept my interest in evolving platforms and continuously updated my apps. For Typography Insight, I have added support for the retina display and added new features such as Kerning practicing. As a big fan of casual games, I have created the game Survi Birds based on the inspirations from the daily life.

Pori Fashion Show
I have been drawing my wife in cartoon style for a while to make her smile. Looking at the accumulated drawings, I started thinking about making something that I can share the joy. Since my wife has fashion design & fine art background, we tried to think about a project that we can create the content together. We designed and developed Pori Fashion Show to foster kid’s dream of being a fashion designer by letting them experience the process of a fashion show with fun and easy playing. With accumulated experience in iOS app development with Objective-C language, it was natural for me to write this app in Objective-C.

Developer Experience Design - Synergy between my two different backgrounds in design and development
As a designer who has a developer background, I always have been interested in connecting design and engineering. As a person who has experienced the importance of UX in software development, I wanted to find a way to contribute to developer experience at Microsoft.
Windows Bridge for iOS
With the successful launch of Windows 10, as an iOS developer, I started feeling that I should jump into Windows app development. I started watching tutorials of C# and XAML, looking at sample codes. One day, I found the project Windows Bridge for iOS which allows iOS developers bring their apps to Windows using existing Objective-C code base. I learned that ‘Developer Experience Design’ team in our Windows and Devices Group has started looking into it.

Suddenly I realized that I am the target user of the project - iOS developer who wants to bring apps to Windows. Since I have been experiencing entire app design & development process from ideation to launch, I thought this will be a big opportunity for me to leverage my experience both as a designer and developer. After deep thinking about my background and future, I thought the best way to contribute to this project is joining the Developer Experience Design team.

From October 2015, at Developer Experience Design team, I led the design effort for Windows Bridge for iOS. Since the bridge is not just simply compile and run iOS apps on Windows, my focus was how to translate the controls and patterns from iOS to Windows smoothly, to achieve best Windows user experience.

Mapping the UX elements of iOS to Windows
Personally, I was able to bring my apps to Windows using this solution - Pori Fashion Show and Typography Insight. Both apps were successfully translated into Universal Windows Platform apps, running on Windows 10 devices. They were demonstrated at Microsoft's Build 2016 Developer Conference as example apps of Windows Bridge for iOS. To share my journey with Windows Bridge for iOS, I have written blog post series on Building Apps for Windows.

Microsoft HoloLens - Exploring the new world of Mixed Reality
Currently, at Microsoft HoloLens design team, I am exploring the new possibilities in the mixed reality space. Personally, I brought my app Typography Insight to HoloLens and shared the story on Medium - "Designing Typography Insight for HoloLens"
