Everything Zack

I’m a software architect, programmer, designer, team leader, and writer. I’ve spent more than 20 years designing, architecting, and building business critical systems that just can’t go down. My software secures banks, hospitals, telecom providers, and government organizations. The code I write runs Fortune 500 financial institutions, hospitals, governments, and keeps people out of jail.

I’m a Senior Technical Staff Member at IBM. I work in the AI Center of Excellence where I help teams all over IBM design and implement AI solutions for real business problems.

Before that I kept the IBM cloud running smoothly. Over 900 developers, 12 regions, and 36 data centers I kept the cloud stable, secure, and fast as the architect of release engineering and testing.

I lead the teams that develop the tools, processes, and practices to ensure the IBM cloud is a platform you want to bet your billion dollar business on.

In the summer of 2018 I wanted to show the cloud team how much we’d all accomplished. Instead of describing the cloud, I showed what it could do… with kittens. Highly available multi-zone load balanced cloud kittens.

Here’s the demo from our Beta 1.2 release.

There’s a lot more information about the IBM Virtual Private Cloud.

Micro Focus

Before that I was an Architecting Engineer and Human Factors Specialist and team leader at Micro Focus. I joined SilverStream in 1998. Silverstream was purchased by Novell, Novell was purchased by NetIQ, and NetIQ was purchased by Micro Focus.
