EngineerVoxeo Labs Jan 2013 - Jun 2013Beijing City, ChinaAfter our company spin-out from Voxeo. My focus is on designing and implementing our SIP Application Server Prism 's new features. I've worked on our NAT-traversal product Horizon's new features at that time. And I had started on working on Tropo's product features at that time. -
EngineerVoxeo Dec 2009 - Jan 2013BeijingI had started to do feature design and implementation for our container since then. It had a new name Prism since then before it's called SIPMethod. And also I've designed and implemented a framework to do JSR309 layer automatic test. The JSR309 layer is the interface for our application server to contact with our media server. It's a whole new feature which need the tests to keep its quality. Also the side-product the media server test framework turned into a good tool to do regression testing for the media server. And we utilized our JSR309 implementation we found that the thread model was not good to scale and perform well so I did the thread model improvements and replaces the Java old IO implementation with new IO. Also I've written a demo SIP servlet product to act as a gateway between SIP and our IMified IM system on top of Prism to gain a business opportunity. -
Software EngineerMicromethod Sep 2007 - Dec 2009BeijingAfter graduation I started working in this company as a software engineer. I learned a lot in these two years before the acquisition by Voxeo. I learned to use Ant as a automatic building tool and CVS as the source control system. I started to learn how to write product-ready Java code since then which are not learned by practices in the high school. I've learned how to use JUnit to write automatic test cases to keep our product on track of continuous integration. At first time I start to know SIP protocol and the basics on implementation a convergent container server. For my working focus I worked on our SIP Presence server SIPoint 's new features and automatic integration test cases. And I implemented a Jython based load test framework based on Grinder to do load testing on SIPoint.
