RAPID (Resource Automation & Productivity Integration Dashboard)o Owned the design and development of a J2EE-based VM provisioning tool widely adopted by QA/Dev across different business units; streamlined the deployment and automated installation of Cisco products on more than 10,000 VM. o Implemented features that were deeply integrated with VMware vCenter; automated away repetitive tasks around VM infrastructure lifecycle management; allowed efficient and on-demand utilization of cloud resources with project based permission and inventory control. o Innovated and built HTML5 web app to allow VNC access to VM with web browser and no third-party plugin required. o Hosted bi-weekly technical training and Q&A session with site admins around the world on using the tool.=======================================================Cisco Webex Meetings Server o Developed user administration pages using Play Framework and owned the design and implementation of an easy-to- use KnockoutJS wrapper framework for page navigation, JavaScript object model and RESTful API service calls.=======================================================Cisco Unified Meetingplaceo Significantly improved reporting performance from minutes to seconds by refactoring event-listening model and analyzing JVM heap usage of a legacy module. o Took the initiative to design and solely own a log analyzer tool using Apache Solr to enable fast type-ahead, full-text search capability on terabytes of log files. The tool made a significant business impact on helping customer support team to reduce turnaround time and troubleshoot system problems.

o Eliminated database overhead in executing geospatial range queries by developing a fast geospatial search engine that indexed and partitioned landmark data into metropolitans using Apache Lucene.o Enabled cross-domain, transparent user authentication by developing a Single Sign-On server and storing master web browser cookie for each user.o Speeded up a media transcoding server by decoupling transcode processing from client request processing; using JMS queues to priority-queued transcoding jobs and dispatched expensive processing to multiple nodes for parallel processing.o Proposed and migrated legacy J2EE application to Spring framework; create wrapper library to ease the adoption and improve engineering productivity.o Prepared Ant/Maven build scripts; deployed and configured WEB/EJB applications running on Tomcat/JBoss in a highly distributed EC2 environment with caching, load balancing and failover.o Scaled out the web-tier by clustering Tomcat and setup a distributed cache manager (Ehcache) that replicates changes to peers via IP-Multicast. o Debugged memory management issues on iPhone in Objective-C; build framework module to communicate with RESTful API hosted on Tomcat. o Designed and developed an Address book synchronization engine to sync iPhone/Android contacts.
