Big-company experience. Small-business focus.
We’re SierraWorks. After years in engineering and operations leadership, we’re putting that experience to work for owners who don’t have an operations team behind them.
Why we built this
Good operations shouldn’t be a big-company privilege.
Start with the systems.
01 · Discipline
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.
Learn what working operations look like.
02 · Experience
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.
Bring that approach to smaller businesses.
03 · Purpose
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.
From people we’ve worked with
Experience, in their words.

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.”
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.”
