Core Philosophies

Marvin Huffaker has built a reputation for trust, transparency, and technical excellence. Each engagement, whether focused on OpenText, VMware, or Sophos security, is guided by the same core principles.

Integrity

Always act in the customer’s best interest, even when it means more work or less profit. Integrity means giving honest answers, doing the right thing when no one’s watching, and building trust that outlasts any project.

Deliver what’s promised and stand behind the work. When something breaks, I fix it. When something changes, I communicate it. Accountability isn’t a checkbox; it’s ownership, the kind that keeps customers coming back year after year.

Maintain a deep, evolving understanding of the technologies that matter most. I invest time in learning, testing, and mastering complex systems so my clients don’t have to. It’s not just about knowing the products — it’s about understanding how they actually work in the real world.

Build secure, maintainable systems designed to last. I don’t chase trends or shortcuts; I architect environments that will still make sense years from now. My goal is for clients to call me for upgrades, not emergencies.

I try to occasionally step outside the office for some fresh air, food, and other basic life essentials. But you can count on me to come back and finish the job...  rested, recharged, and ready to solve the next problem.
