I've been developing iOS and Android application since 2009. I am familiar with iOS native development by using both of Objective-C and Swift, also familiar with Android native app development.

I have fully experienced in Swift language from all versions. I've developed car driver parking social application in Swift 1.0 and Swift 1.1, And developed SwitcheZ USA in Swift 2.2 and upgraded it to Swift 2.3. Since 2016, I have developed apps by using Swift 3, and now I am using Xcode 9 with Swift 4.

I have started iOS application programming since 2011. In 2011, iOS app has been developed by using Objective-C, not Swift at that time. So most apps that I've developed in 2011 ~ 2014, I've used Objective-C for app development. I am very familiar with Objective-C frameworks and libraries such as AFNetworking library (REST api processing) and TPKeyboardAvoiding (iOS soft keyboard processing). I have experienced in both of Xib-based UI configuration and Storyboard-based UI configuration. Also, expert level in auto layout and constraints.

I have started my programming experience from Android programming. Android OS is an Open Source, so I have researched about Android OS when I studied in the college for Open Source Theory. It was a good start of Android programming for me. Since 2009, I have started Android application development and published them to Google Play Store, Amazon App Store and Barnes & Nobles App Store. I have developed Android tablet games and apps in 2009 ~ 2011 and some of the game entered into TOP 10 hit games in Barnes & Nobles Nook tablet App Store. In 2011~ 2017, I have worked for data management application, REST api connect apps, camera processing apps and etc. mostly. I am available for both of Eclipse and Android Studio. I have developed Android application in Eclipse by 2015, but since 2015, I have completely switched my Android app development environment to Android Studio.
