2. 1. Streamage
Windows Phone Application
CREATED
Q3. 2012
Platforms / Frameworks
Windows Phone, Windows 10 Mobile/ Silverlightfor Phone
Screenshots
Brief Description
I always wanted to control the hardwareof the machine. In accordancewith the advent of Windows Phone at 2011,I could have
chanceto write scriptfor operatingsmartphone’s hardware,such as camera,gyroscopes,etc. in the way of manipulatinghardware
specs,I decided to make camera application.
This application can configurethe duration of time to capture photos for getting video-likeimages such as flowingthe star on the
night sky,in other word, this application is aboutmakingtime-lapsevideo camera application.Though there’s advanced application
already in the market, I could have precious experienceto make application and monetizing.
Until now, this application has sold about30 times at the Windows 10 mobilemarket place.I have plan to migrate code for running
on the Android by usingXamarin framework and Windows platformby usingUWP.

3. 2. Bottle in the Sea
Silverlight Web Site
Created
Q2. 2012
Platforms / Frameworks
Windows Server, SQL Server, IIS / Silverlightfor Web,WCF
Screenshots
Brief Description
This web site is for chatting with random users. The idea was the man in the isolated island to try send messages over the sea by
putting letters into bottle. This idea is quite prevalent in application of Android or IOS, but I was trying to implement idea in the way
of Silverlightfor Web.As making this web site, there was advent of Windows 8.Thus, I wanted to implement of design consistingtiles
likeWindows startscreen on the web. For makingsuch design surface,I choose to use Silverlightfor web.
To communicate with database, I needed to make transporting layer by using WCF. I could use the animation code block to animate
the bottle over the sea.
Though Silverlight is quite deprecated when it comes to making web application due to web standard of HTML5, the code blocks
written in XAML can be used as a basefor developingother type of application.

4. 3. SejongTalk

Platforms / Frameworks

Screenshots
Brief Description
This websiteis aboutcommunity website for students in Sejong university thatI went to when I was undergraduatestudent. University
in Korea has their own unique website to gather their student for communicatingabout information of their campus life. I wanted to
make flea market over the web sites to exchange their properties likehandbooks.In addition of it, I wanted to make forum to debate
about the problem in the university to make our college more polishingthan ever before.
The code to be used to make this web site was reusable such as the bulletin board code module, or the chatting module by using
SignalR.Thus, when I make the other projectto constructweb site, I could make use of it repeatedly.

ASP.NET MVC Web Site

Platforms and Frameworks

Screenshots
Brief Description
This website is forum or magazine website for collecting the information about .NET develop. I wanted to centralize the information
about .NET develop. Especially as a Korean developer, I thought it would be great if I gather the other Korean developers to share
programmingskill sets.
This website is made by bunch of programmingframeworks. The backend service,server sidecode, is implemented by ASP.NET MVC,
ADO.NET Entity Framework. And the frontend serviceis consistingof Bootstrap,JQuery, etc.
After creatingthis,I wanted to make the website by usingonly JavaScript,and TypeScript.As mostof developer know about the reason
for using JavaScript on making websites, I thought it would be great if I use JavaScript for not only constructing frontend service but
also implementing backend servicelikehosting. Thus, I started to make SPA, SinglePage Application,by referencing the original code
in this project.

Brief Description
This application is console based program for managing SQL database by using ADO.NET transporting classes. Thus, a lot of thi s
console’s command useconnection stringto connectto existingdatabase,butby usingthequery databasecan becreated fromscra tch.
I make this application for managingdatabasetaskssuch as databasebackup tasks.Back-up tasksprocessed atfirstcopyingtherecords
from sourcedatabasetableto destination.
In addition to that, this console can execute queries, deleting databas e, inserting seed values on the database. The structure of
commands in this application is inspired by the command-let in PowerShell a lot.
I’m currently consider to make XML fileto store commands for managingcommands as command module for consideringex tensibility
of application.

8. 7. Video Splitter
WPF Application
Created
Q2. 2016
Platforms / Frameworks
Windows / WPF, WPF Bootstrap,MediaToolkit,BCL
Screenshots
Brief Description
This application is for splitting long video into small video consisting duration of 30 seconds. I developed this application as I have a
hobby to make subtitles of Korean for studying English. When I make subtitle from the long movie, I couldn’t even try because the
duration makes me frustrated mostly. Therefore, I needed to make tasks more modular and smaller than before.
For core functions of splittingvideo,I should have used MediaToolkitlibrary which is open sourceproject for transforming ffmpeg (C
languagelibrary for editingand transformingvideo) into C# wrappinglibrary.
