Last updated on July 7, 2020
I have 3 years of experience in Objective-C and 6 years of experience in Swift language, and made apps on most of Apple's platform, such as iOS, iPadOS, watchOS, and macOS. I've been developing iOS apps since 2012 when I was still a student, and have worked on multiple startups and big companies ever since.
Having lived in Dalian, China for 9 years and currently living in Seoul, Korea, I speak Korean, English, and Chinese.
I arduously follow Apple news and lastest Apple technology. I like experimenting with new information, and share what I learned and experienced and have presented in 9 iOS conferences. I am always inspired by the elegance of user interface and delicacy of API designs by Apple.
