Let's meet the team below:

Michael also has significant expertise in software optimization, database architecture and design, performance testing, performance troubleshooting, and process improvement. Technical skills, tools, and languages include a deep knowledge of IBM i performance tools such as the iDoctor suite (Job Watcher, PEX, etc), Collection Services, and DB2 SQL Performance Monitor, and fluency in most supported IBM i (iSeries, AS/400) languages, including all versions of RPG, COBOL, and DB2 SQL. Michael has specialized in IBM midrange systems since the introduction of the AS/400 in 1989. In early 2002, he participated in the launch iSeries and DB2 based web site. After a merger with Expedia and a few years in large corporate management as the Director of Application Engineering, he returned to the consulting world and his niche in IBM midrange application code modernization and optimization.

Doug Mewmaw

As a 30+ year veteran in the IT industry, I have always been passionate about both customer service and helping others. I have been to hundreds of sites worldwide, and it has been one of the most rewarding opportunities of my life to work with the talented and dedicated people in the IBMi community.

I started my company, Peak System Performance, because I recognized a void in the area of performance within the IT world. Our company was dedicated to all aspects of performance. We helped companies of all sizes ensure their mission critical systems were running with A+ service levels. I remain committed to this cause.

I am excited to be expanding the services Peak System Performance was able to offer by creating a new company, Greymine with Gary Patterson and Michael Brock. Together we are better, and together we can offer even more expert services in the IT community. My passion for and dedication to performance remains. I am thrilled to be part of this new company where performance remains one of our core values.

At Greymine, we will continue to focus on performance so you can focus on growing your business.

I look forward to working with you, and perhaps golfing with you!

Customized On-Line Education / Webinars

It's not easy to travel - especially nowadays. The good news is we offer customized education and webinars based on your organization's needs.

Why our Education Program is Different

We've spoken to CIO's, managers, and the system administrators in the trenches. Their top complaints are always the same:

• The class cost per person is just too high.
• The class schedule is always in conflict with our company projects.
• I can’t afford for my staff to be away from the office.

At Greymine, we agree that structured education and training should be easy. Our award-winning instructors have not only created a world-class curriculum, but we’ve created an education program where one vice president said,

“This was the best IT investment I’ve ever made for my team.”

It was great feedback and proof we were doing things right.

Why are we different?

• We schedule classes based on your availability (First Come, First Serve).
• We travel to you (Temporarily suspended with Covid-19).
• No per person costs (We charge one price for as many people as you want to attend.)
• We create customized classes based on your needs.
• All classes can be attended remotely.
