SUMMARY:

• 7+ years of strong experience in installation, configuration, & administration of middleware technologies, such as Apache Tomcat, IBM WebSphere Application Server, WebSphere Portal, MQ, JBoss, Webservers (IBM HTTP Server, Oracle One/IPlanet, Apache Webserver, EWS), Web Content Management (DAY/Adobe CQ/AEM, CRX, Commonspot), Monitoring (Introscope, Sitescope, HP Diagnostics, ITCAM, PRTG, SolarWinds), MongoDB, Cordys, Livecycle, Jackrabbit, James on Unix (Linux, AIX, and Solaris) and Windows environments.
• Installed and configured WAS 6.x/7.x/8.x, Portal 6.x, JBoss 5.x/6.x, CQ 5.x, AEM 6.x, CRX 2.x/3 (Jackrabbit Oak), Tomcat 6.x, JRun 4.x, Commonspot 9.x, & MQ 6.x on UNIX and Windows systems.
• Installed and configured webservers, such as IBM HTTP Server (IHS) 6.x/7.x/8.x, Oracle One/IPlanet 6.x, Apache HTTP Server 2.x, EWS 2.x, & Microsoft IIS 6.x/7.x. To provide single - sign on operability, installed/configured SiteMinder agent (webagent) for password//2-factor authentication. For facilitating routing from webserver to the appropriate application server/java layer, generated plug-in on the application server and integrated mod jk/mod cluster.
• Deployed J2EE enterprise/ecommerce applications/portlets (EARs/WARs) to application servers, portal servers, jboss/tomcat instances. Created datasources for connecting application code to the databases and configured SAPJco for seamless integration between JAVA code and the SAP systems.
• Extensively utilized my proven problem solving skills to write scripts for automating numerous tasks, such as for code deployment, server instance restart, datasource creation, extracting the salient characteristics of the appserver and JBoss instances. Written scripts are so powerful that with those scripts, migration of Websphere environments from RHEL 4.x to RHEL 6.x has eliminated manually interactions to a very high level of degree. I have also written scripts for migrating WebSphere environments to JBoss environments. Scripts gather all the salient characteristics of the infrastructure set-up and then based on that script creates JBoss instance. Employed sound knowledge of Jython/Python/WSAdmin/Shell/Cronjob/cURL for creating scripts.
• For CQ/AEM perspectives, deployed packages (ZIPs) and used cURL/Shell based scripts for automatic package build-up/installation/download/data store garbage collection. Set up clustered authors and publish instances; set-up replication agent/dispatcher flush agents; integrated LDAP/SSO/dispatcher; and actively used Felix/CRX/launchpad/admin consoles. For AEM, installed/configured MongoDB replica-set and integrated author instances with the MongoDBs.
• Provided infrastructure/middleware support for 200+ web applications and a range of APIs/web services for inter-operability between the applications; and acted as team lead/SME on ad-hoc basis.
• Proven ability to work independently; as a part of a team; or as a team lead demonstrated professionally at Louisiana Tech, Penn State, Confidential, & Confidential .
• Demonstrated innovative problem solving skills through US Patents, licensed software technology, 10+ research publications, reports of inventions, & two books/dissertations, and received Spotlight from Experis (Man Power Group).
• 5+ years of teaching/mentoring experience; Board member/reviewer of numerous computer science journals & conferences; provided 24x7 on-call supports (pager).
