### Principal Software Engineer @ xAd
Jan 2016 – Jan 2017 | mountain view

### Principal Software Engineer @ Telenav
Jan 2016 – Jan 2016 | Santa Clara, CA
•	Built big data platform by using hive, defined ETL process for log data, extracted key information from raw data and construct user profile, to be used in personalized routing systems.
•	Improved cloud routing performance from end to end by reducing payload.
•	Designed and implemented cloud routing/map service architecture and make sure it support global market.
•	Designed and implemented ECO routing, including user story, validation, testability, implementation, engaged PM(product manager) and QA in the whole process. 
•	Designed and led a team to build a comprehensive routing/guidance automatic test system.

### Staff Software Engineer @ Telenav
Jan 2013 – Jan 2016 | Sunnyvale,CA
•	Designed and developed turn-by-turn guidance, lane guidance and natural guidance.

•	Designed and developed personalized routing, which enabled the navigation system to constantly learn from user's driving behavior.

•	Unified cloud and embedded routing/guidance API and related code, reducing the maintenance cost and making user experience consistent, whether it is connected or not.

### Senior Software Engineer @ Telenav
Jan 2009 – Jan 2013 | Sunnyvale, CA
•	Built cost model, which improved route quality and "Estimated Time of Arrival" service greatly.

•	Built road intersection model, which simplified road network in reality.

•	Developed map data format and compression algorithm, built data pipeline.

•	Led map team in both automobile and mobile projects, provided routing and guidance services.

### Manager, Map Group @ Telenav
Jan 2006 – Jan 2009 | Shanghai, China
•     Built up the Shanghai map team from 10 engineers to 40+ engineers.

•     Managed and led the map team to develop and maintain all navigation backend services, including routing, guidance, geocoding, reverse geocoding and vector map based on the Telenav home-brewed map engine.

•     Built map data test and evaluation system.

•     Developed many map data compression technologies, making the whole North America map data as small as 1.3G.

### Manager, Map Engineering @ Telenav
Jan 2005 – Jan 2006 | Shanghai, China
•	Led a team of 7 in building the first Telenav home-brewed map engine.

•	Developed traffic-enabled routing algorithm.

•	Developed navigation data format which is the foundation of the map engine.

•	Developed exchange map data format, which can make data pipeline independent of vendor's data format.

•	Developed map data pipeline, which can compile and verify data.

### Senior Software Engineer @ Telenav
Jan 2004 – Jan 2005 | Shanghai China
•	Developed routing and guidance service API and algorithm..

•	Invented multiple-paths algorithms, which addresses latency issues due to data transferring between server and client.

•	Invented local-reroute algorithm, which enables cell phones to continue to provide navigation service with limited on-board map data, therefore reducing the dependency on mobile network.

### Senior Software Engineer @ Stone-mti Shanghai Inc
Jan 2002 – Jan 2004 | Shanghai, China
Designed, implemented and maintained electricity facility GIS system.
