Created trafficjam.today, a web service that provided both real time traffic information visualized through Google Maps API and historical traffic information visualized through Highcharts

• Provided a user-friendly interface that used color overlay to highlight traffic condition and allowed users to click a street section and discover the historical traffic patterns

• Built a robust data pipeline that allowed for the distributed processing of large data sets across a cluster of computers (Amazon Web Services) with high throughput and low latency

• Deployed the back-end servers with Kafka, HDFS, Spark, Storm, Cassandra, and Flask

• Historical data was aggregated using Spark batch processing for further statistical analysis purpose while real-time data flowed through Storm bolt with tick-tuples

Software Engineer: 3D Face Recognition (subcontractor of National Security Agency & Scitor Corporation)

• Created a low-cost 3D face recognition system that benefited NSA on identifying criminals

• Provided race & gender based generic face models for 3D face synthesis using 2D images

• Achieved high accuracy 3D face recognition on NSA mug shots database using the face model synthesis algorithm and 3D surface registration algorithm

Research Fellow: Computational Archaeology (founded by National Science Foundation)

• Automated the mending process of the excavated broken artifacts in a virtual 3D environment

• Developed a novel piece-wise 3D surface modeling technique specialized in shards analysis

• Designed a high efficiency curvature adaptive B-spline fitting algorithm to preserve the local geometry features on which the mending process depended
