About Me

Hi! My name is DONGGEUN JUNG. Call me Dennis.
I'm looking for an Android native application developer position.

I have 5 years experience of Android native application development using Java.
2 year of Tizen, 1 year of Hybr...xperience of Android native application development using Java.
2 year of Tizen, 1 year of Hybrid App using Cordova, 1 year iOS App using Swift, 
and 8 years of Visual C++ development.
I wrote 6 programming guide books.
The subjects are Android, Java, Hybrid App, Visual C++, and Tizen.
I have Green Card, and Social Security Number.

My best skills are making architecture using Object Oriented Programming,
and making UI custom controls using Canvas API.
I make architecture as a framework. It's a kind of reusable library.
So main source code is simple and management is easy.

I usually use MVVM design pattern.
To communicate with server I use Retrofit API.
To store Data I use ViewModel and LiveData.
To display data on Activity or Fragment I use Databinding.
To perform a job taking long time, I use RxJava instead of AsyncTask.

I wrote a book about making UI custom controls.
Such as picker control or chatting timeline.
So I am good at making UI custom controls using Canvas API.

I have 8 years experience of C++, and 5 years of Java.
Additionally I wrote Java guide books.
So my Java skill is excellent.

I have developed over 10 Android applications, 
and some of them are uploaded in Google play store.
When I worked for Samsung, I developed a part of source project,
and when I worked for small companies I developed the whole part of source project.
Additionally, I wrote android SDK guide book. 
So I can develope all part of Android application by myself.
