Why we built this

Good operations shouldn’t be a big-company privilege.

01 · DISCIPLINE

Start with the systems.

Our founder started in the U.S. Navy as a Quartermaster in submarine fleet operations, an environment where process discipline and precision aren’t optional. That mindset carried into engineering leadership.

02 · EXPERIENCE

Learn what working operations look like.

At Adobe, our founder led engineering and product operations for organizations managing hundreds of millions in annual revenue. That experience spans 20+ years in software: building teams, shipping products, and connecting systems so decisions and work could move.

03 · PURPOSE

Bring that approach to smaller businesses.

SierraWorks works for the owner. We look first, build what’s worth building, and run it for you.

HOW WE WORK

We start by listening to the people doing the work.

We talk with the people doing the work, in the office and in the field. We tell you what’s worth doing and what isn’t, including when the fix is a process change and no software. Then we set it up with your team and run it. Think of us as your AI operations partner: the people who work out what you need, build it, and keep it running.

Making complexity approachable

“His ability to make the most complex concepts seem attainable and communicate highly technical information to any type of audience make him a key player for our team and the company.”

Operations & Program Management · 2013

Turning ideas into working systems

“With just a marker and a whiteboard, I’ve witnessed him solution dozens of intricate routines and logic flows… he carves up prototypes in record time.”
