ACCOMPLISHMENTS

Learning new technologies is my professional passion. I chose to build small-scale projects POCs to learn latest trending softwares in the market. Recently I developed a Log Analyzer application OWL inspired by elasticsearch.org. I made it very light just a WAR file which is compatible with any web/application server. Along with log analysis, it also provides information like JVM properties, cluster info, and other information of web/application server. Technologies used are, ExtJs MVC 4.2, spring data, batch, Integration, web mvc , MongoDB, Apache Lucene.
