I build the systems that scale. And the frameworks that make them last.
I led the rebuild of the largest corporate hiring system on the planet. Twenty engineering teams. Sixty-six countries. Billions of transactions a year.
Few leaders have operated at that scale. Fewer have designed the systems that made it work.
Frameworks determine whether execution compounds or collapses.
Over twenty years across Amazon, Microsoft, and multiple CTO roles, I have learned that organizations do not fail because of technology. They fail because the underlying operating system does not scale.
At Amazon, I did not inherit a model. I built one. How roadmaps are created and tracked. How the critical path is defined. How launches are governed. The full lifecycle from idea to production across 66 countries.
That system did not exist before.
At Microsoft, I served as the virtual CTO for the largest for-profit healthcare provider in the United States and closed the largest Healthcare Enterprise Agreement in company history, exceeding $268M.
At Anytime Telehealth, I walked into a platform cratering under load during COVID and scaled it to 5,000% growth in sixty days. The system was unstable, the technical debt was severe, and the infrastructure was not built for the demand it was facing.
As a three-time CTO, I have built both the systems and the companies they run.
The record, in numbers.
12B+
Annual transactions. One platform. The infrastructure behind every corporate hire Amazon made globally.
$268M
The largest Healthcare Enterprise Agreement in Microsoft history. A record that still stands.
5,000%
Platform growth scaled in under 60 days. The platform was on fire when I arrived.
$14M
Legacy system dependencies eliminated through automation-first practices at Amazon.
50,000+
Recruiter hours reclaimed annually through process automation. Not reduced. Reclaimed.
I take on a limited number of fractional CTO and advisory engagements.
If you are a PE firm evaluating a portfolio company, a founder scaling beyond early-stage execution, or an enterprise in transformation, we should talk.
Let's TalkThe frameworks I build professionally and personally come from the same instinct.
I also write and build frameworks under the name Ross Charles, exploring what high pressure does to the people inside demanding systems and why the gap between understanding yourself and actually changing is not a willpower problem.
The Identity Pattern Framework and the yourpatternmap.com assessment came out of that work. Leaders who encounter it describe it as the most clarifying thing they have found.
If that sounds relevant to the work you do, it probably is.
