Online Issues Troubleshooting
 Resolve annoying online issues: messy filename and messy UI, cursor jumping issues in safari, automation
stability, data loss, client and server version compatibility, etc.
Page Load Time Optimization
 Analyze user behavior: Optimize the presentation boot sequence based on history user operation.
 Optimize client-server loading: Reduce the round-trip between client and server by incremental loading.
 Reduce user perceived PLT from 11s to 6s: Create new thumbnail controller, change logic of conversion
service, load preview data earlier from server, present slide preview data on browser.

stitching algorithms. Improved the performance of simulating one stroke from 10 minutes to almost real-time.
 Built a head pose estimation Android app by analyzing user head image with accuracy above 90%. Use
HAAR feature detection, image registration algorithms.
 Implemented hand gesture recognition Android app by using hand image sequences. Use background
extraction, feature extraction algorithms. The accuracy is above 95%.
Part-time Software Engineer at Hangzhou Chixiao Technology Startup Company 09/2012 - 11/2013
The medical system is the most important project for this startup company. I came up with the whole architecture
design of the project and was appreciated by the founder. We designed the framework and module together. In
the following months, I lead 3 more developers to implement it. In the end, it worked efficiently.
 Database management, client-server communication, hardware-software communication, real-time result
generating, data visualization, authenticating users, etc.
