PROFESSIONAL PROFILE

24+ years experience as a software development engineer with extensive experience in all aspects of SDLC, requirements gathering, mentoring and technical reviews. As a long tenured development leader in the information management technology sector at IBM I have been involved in numerous industry leading and world record benchmark efforts as a developer and performance analyst for the IBM DB2 LUW team. Some of my work has directly contributed to millions of dollars in revenue for the DB2 LUW team as well as the IBM Corporation as a whole. I have received individual and team awards for my efforts and continue to be very enthusiastic about technology going forward. As a technical professional I am quite proud of the fact that my skills have always been well utilized and sought in all the areas I have worked. I deliver projects on time and on budget. I pride myself on being very adaptable as can be seen in the varying projects/roles I have been involved in. I have always been considered a go to person where I can be (and have been) pulled from one project and injected into another late or lagging project and will not disappoint in the effort given to put the project back on track.

PROFESSIONAL EXPERIENCE

Software Developer Contract

Responsible for the development of a SaaS version of their product. The current version of the product requires a full installation on the client machines along with another 3rd party product that is used as their UI harness. The new product will give the customer the option of going full SaaS with no installation on their part or a partial SaaS where the back-end database can be located at the customer location and will therefore require some installation of these components (namely MySQL, PHP and a Web Server – likely Apache).

As a member of the DB2 for LUW version 10.1 (aka pureScale) development team I was responsible for the architecture, design, development and testing of the PD (Problem Determination) feature.

GPFS (shared file system)

uDAPL (direct access transport layer)

TSA/RSCT (system automation product) and

CF (clustering facility)

This feature was vitally important because a major requirement of the product was that customers would not need to be experts on the new add-on products in order to diagnose and/or collect problem reports.
