During my internship with ST Electronics, I worked with the Datamark team and developed an Android app and an iPhone app that is capable of embedding and retrieving digital watermarks from images taken using the phone's camera. These watermarks could be used to prevent image forgery, enforce copyright protection etc.

I founded the Mobile Apps Club at Carnegie Mellon University with another friend in Spring 2011 to provide a meeting place for fellow enthusiasts to share their ideas, discuss experiences, and develop some cool products. We have a website in the works, so watch this space!

In Spring 2011, my team participated in the 17th Annual Mobot Races and constructed a MOBOT using a Tamiya car and a Nexus One. We did that with very primitive tools - a few months before Android released their API for Android-controlled devices. The app used OpenCV to process the video frames and calculate the vehicle's trajectory; motion control signals were sent through the audio jack.

This is one of my first Android apps. It loads your tasks from Remember the Milk and allows you to re-order them by dragging and dropping the rows. You may also complete/hide tasks. It updates itself daily at midnight, but you may also refresh it manually. Still under development! Deprecated after I moved to another task manager.

Developed by my team for Noms Right Now, this app uses the website's API to display a list of restaurants and other eating places around CMU that are open at the time you use the app. Get it here. Deprecated in favor of a mobile-optimized version of the website.

I developed this Wordpress plugin in 2009 when Wordpress had just introduced their Shortcode API. It allows users to embed contents of their Google Docs or Spreadsheets in their blog posts by using shortcode or by drag-and-drop. More information is available here and here. (This plugin has been deprecated in favor of more secure ways to embed documents and spreadsheets.)

Just before I entered college, I designed a prototype and developed a web application framework for Dunman High's Chinese Learning Portal. It was fun using CakePHP, prototypejs, and scriptaculous. The project was handed to a web design company for further development.

This was my team's entry for ThinkQuest 2006. At that time, we probably over-used Javascript and CSS, and the pages took ages to load. While I was preparing this list of projects, I visited the old link and was surprised to find that the website loaded pretty quickly and was still in good shape despite years of neglect.
