• All these application had to be controlled and monitored for health and performance issues.
• Designed and implemented command line and network based application for this purpose
• QC integration using QCS. PRSS (delivery division of the NPR) uses HP Quality Center for the development defects and requirements tracking and proprietary system for users’ feedback.
• I designed and implemented synchronization between user feedback handling system and HPQC using HP QC Synchronizer platform.
• Distributed delivery system. Current implementation of the delivery system is based on the combination of the satellite multicast system, 3rd party hardware, and Content Depot system.
• New system supposes to move the delivery to the Internet. New delivery system will be based on the popular P2P protocols (similar to BitTorrent).
• Personally provided design, mathematical model, simulation prototype and preliminary design of the future delivery system.
• Facilitation and support of the SCRUM methodology. Integration of the JIRA (Greenhopper plugin) with Subversion source control system.
• Establishing process and traceability rules and requirements for CD2 project.
• Development and maintenance of project estimation model using requirements, user stories and calculated burn rate as parameters.
• Design and implemented CD search system using ElasticSearch (product built on top of Lucine).
• Search application was running on two servers and performs asynchronous indexing of the specific DB tables and text files.
• Implemented index synchronization between primary production and backup NOC sites.
• Performed integration between Portal based application and search engine.
• Design and partial implementation of the transition from Portal to the lightweight, SOA architecture.
• New implementation was based on the Spring 2.5 container (Spring MVC, transaction management, IoC, and autowiring).
• Minor projects. Streamlining the build system, migration from CVS to Subversion, migration from Weblogic 8 to Weblogic 10.
