About SierraWorks

Big-company operations experience, built for small business.

I spent 20 years inside large engineering organizations. SierraWorks is how I put that to work for businesses that have never had access to it.

Why I built this.

I started my career in the US Navy as a Quartermaster on submarine fleet operations — an environment where process discipline and precision aren't optional. That mindset followed me into 20 years of engineering leadership at software companies across the country.

At Adobe I ran engineering and product operations for organizations managing hundreds of millions in annual revenue. I built teams, shipped products, and learned what it looks like when operations actually work — systems connected, data flowing, decisions not bottlenecking at the top.

Then I looked at how most small businesses actually run. Spreadsheets. Manual handoffs. Work that eats hours every week that nobody has time to question. The gap between what enterprise companies take for granted and what small businesses have access to is enormous — and almost nobody is trying to close it.

SierraWorks is how I close it. We find exactly where your business is leaking time and money, build the automation that fixes it, and hand it to you running.

The mission

Every business deserves operations that actually work.

Enterprise companies have entire teams dedicated to finding inefficiencies and eliminating them. Small businesses have the same inefficiencies and nobody to find them. That's the problem SierraWorks solves.

We start with a free AI Scorecard — one 30-minute call, and we hand you a one-page score of where you're leaking. No cost, no commitment. If you want to build, we build. If not, you keep the Scorecard.
