Visa Middleware Engineer Highlands Ranch, CO

We support weblogic, tomcat/tcServer websphere,jboss/jws apache, iis. Daily support would be building these environments, deploying, upgrading, patching, migrating environments. We have specific projects that we pick up. I have worked on migrating fico environment to vm environment ; maintaining server certificate currency, building new environment for several different apps, worked on moving apps from weblogic to jws

October 2014 - October 2015

IGT Middleware Engineer Remote/Telecommute

This is a project based consulting position. Projects include:

•POC Weblogic 9 to Weblogic 12, wls9 to tomcat8, wls and tomcat to virtualization ( vagrant, docker, flocker, puppet, chef)

•Helping out on Break/fix issues with JBOSS and websphere, tomcat and weblogic when possible.

•Worked on refining deployment process

•Worked on resolving problem tickets

•looking at weblogic 12 on certain environments

•Helped in migrating from Weblogic9 to Tomcat8

Main environment contains weblogic, websphere, jboss, apache, oracle db, tomcat6. Part of the day to day maintenance is to keep these environments up and running, deploys, break/fix, etc.

November 2013 - October 2014,

ING Sr. Middleware Engineer Remote/Telecommute

This was part of a migration effort. Moving environments from IBM to in house support. This involved moving whole environments using pack/unpack, making modifications to those envs according to in-house standards. There were some upgrades along the way as a lot of the environments were wls8. So moving from wls8 to 11g or 12c . This also involved working with the load balancer and their frontends (iplanet) making appropriate changes there to ensure everything was point to the right place. Along the way, I did some tuning and scripting to make things smoother. Also did configuring on new environments as they came up.

Day to Day tasks :

maintenance of the JVM farm, which consistd of weblogic, webshere, jboss and tomcat.

July 2012 - November 2013

Wipro Sr. Middleware Engineer Remote/Telecommute

•Managed, maintained, troubleshot Weblogic, Websphere, JBOSS, tomcat, in production environment

•Maintained service pak levels, scheduling SP installs and security fixes

•Built Weblogic instances to standard (8.1,9.2, 10.0, 10.3.X[11g]) WebSphere 8.5.5

•Maintained wls portal environment. This involved deployments, configuring agents, creating users/groups, maintaining entitlements, managing content according to lifecycle.

Note: This is an environment that supported several hundred boxes across several accounts. We supported mostly Linux and Solaris installs. Captial One was a customer that used OpenStack to manage their environments. They have a very fluid need for environments. Creating a generic template and then to make customization changes worked well for this customer. Weblogic releases were from 8.1.X to 10.0/11g. We supported apache administration/upgrades/configs/installs as well. Here we have a team of 4 Weblogic Admins. We all supported our projects but also shared in a monthly oncall rotation that would involve supporting everything middleware; i.e. webmethods, apache, certificates, etc.

January 2012 - July 2012

Lockheed Martin

Sr. Middleware Administrator Arvada, CO

Lockheed Martin is a Websphere shop. We worked with developers in the QA and DEV environments to help maintain their ROSS application. Worked on a big migration project moving and upgrading their websphere, COGNOS, LDAP environments to new data center. This involved building out a new environment according to specs that were presented. Their environment also maintained COTS products as well as apache, IHS, and database connections. Helped in troubleshooting all of the above environments. Created some scripts to update LDAP; also created documentation for other processes that needed that.

July 2010 - December 2011

Wells Fargo

Sr. Weblogic Administrator Remote/Telecommute

This project was to install, build out and configure the new Pegasystems environment. This involved building out 150 servers across DEV, UAT, PFIX, BCP and PROD environments. Configuring the pegasys app involves configuring JMS servers, and JDBC datasources so I worked closely with the developers, DBA’s, network group and SA’s. I also installed/configured apache frontend to work with weblogic proxy plugin.

Worked with HPSA as a delivery tool and other Wells Fargo proprietary tools. In the process was put in the oncall rotation to help maintain, troubleshoot and assist in issues as the arose with other weblogic, apache, NDM, and sunone. The project OS platform was linux/redhat 5; some of the legacy environments were Solaris based.
