Developed a web based data warehouse applications (DWA). Application allow user to create and change model in runtime. Deployed and supported state level information system (based on set of DWA) which accumulate data for that state (oil and gas production, forest fires dynamics, city buildings, hospitals equipment, car incidents and lot of other). Implemented data access and business layers. Data access implemented using JDBC.
Designed and implemented overall architecture of application attributes search and result representation. Implemented file recognition (OCR, PDF, MS Office and other text formats) and context search (Apache Lucien and Solr).
Developed comprehensive security rules. Implemented integration with LDAP.
Developed data import and export mechanisms using XML, MS Office and data specific formats. Data can be imported (exported) from (to) file system, REST or SOAP web service.

Integrated with 30+ systems: public API, existed web service, developed based on provided WSDL.
Experienced with Oracle Service Bus: message type transformation (REST business service to SOAP proxy service), caching, data transformation, web service routing, call chains of multiple services, Java Callout.
Developed background tasks using multithreading: attribute calculation, import and export job scheduling, system maintains. Using Java concurrency API.
Developed cache support and transparent cache invalidations.
Added support for running application on cluster.
Designed and developed database version and migration mechanism. Then updating application database version check and upgrade a lot easier.
Adopted application to run on JBoss and WebLogic Server, initially it deployed only on Oracle Application Server.
Created Ant build script which build and deploy EAR to application server (oc4j, JBoss, WebLogic). Build script take profile name and build application with required: database, security rules, configuration file.
