More recently, starting 2012, I have used javacript libraries to develop HTML5 applications. I am particularly efficient at translating Flash interactive Actionscript 3.0 games and interfaces into HTML5 equivalent. The two languages share high level of similiarity. However, one has to account for poor canvas performance of HTML5, especially on IPads. As a result, direct translation from Flash to HTML5 creates very CPU intensive applications.
My latest HTML5 app for playwhatyoufeel.com guitar instructional player embeddable on other people's web sites utilizes Kineticjs library, collision deletection, event triggers, event listeners, XML dynamic loaders, and image loaders. (6,000 lines of code)

I also creates shell script programs running on crontab job schedules to clean up unnecessary processes running on the server and background.  


In 2006, I developed my entire site flashlands.com, all of its dynamic pages using queries from mysql using select, delete, update ,inner joins, outer joins, and subqueries. These procedures help visitors the most relevant search results and suggested content, and zeitgeist of the time. 
(10,000 lines of code)
I developed a back-end calendar system to schedule various events with binary uploads and email sending functionality with an InnoDB enabled database.
In 2007, as a Yahoo engineer, I designed an Actionscript animated dashboard displayed on a 25 inches LCD screen representing data from internal Yahoo operations using Actionscript 2.0 for broadcasting daily metric values such as system outages, server-farm down times, and internally issued tickets for Yahoo! Internal tools operation team in Building B at Sunnyvale headquarter.

In 2008, as founder of 6billionpeople.com. I fine tuned the performance of PHP and MySQL on Linux based server by modifying php.ini, .htaccess, httpd.conf and created indexes on tables' attributes frequently queried by users (8 million recorded page views). 
In 2013, I have downloaded entire Wikipedia articles and parsed 2 million articles using perl into tables to create a knowledge based game. In order to filter the common knowledge from the obscure knowledge, as well as suggested concepts with similar meanings, various table indexes were applied on key attributes such as title and search volume so that query can be returned quickly.  

In 2003, As an intern as Stifel Nicolaus, I developed MS-SQL Databases and stored procedures on the SQL Enterprise Manager for the investment banking company’s intranet. 
Created an entire security site in ASP and stored procedures utilizing INNER JOINS and sub queries that permit different levels of access and control for employees and managers to respond quickly to drastic events such as fire or a terrorist attack. (1,000 lines of code)
In 2008, as Quantitative Programmer/Trading Desk software engineer

A server version of the same strategy game also uses Java server to broadcast game status message using XML tags.
In 2013, working at Coquiz.com, I developed a Java server to accept multiple user connection for a knowledge quiz game using Wikipedia articles. Each server is allowed to connect with up to 8 users and the server is waits until all users are ready for the game by using timeout function. The server judges the answer and reward points for correct guesses and broadcast the result to all users. Finally, the server shuts down when no one is connected to the port. (1,500 lines of code)

I mainly developed my games and applications for the Android system using Flash AS 3.0 for various clients. I am an expert in Flash AS 2.0 and 3.0, I have over 15 years experience with Flash. (50,000+ lines of code written in total) Which is fairly similar to Java because of its object-oriented design approach. The latest Adobe software bundle easily converts the final flash application into Android compatible applications by using Adobe Air package. One can specify the attributes in a XML based manifest file.
Sometimes, shock-wave files from Flash can be converted into apk file using Android platform MS-DOS command, which then can be installed and run on user client.


I am an expert in Flash, I have created hundreds of Flash applications ranging from games to apps. I am proficient in both AS 3.0 and AS 2.0 framework and translated the languages between the two.
