I build the systems that scale. And the frameworks that make them last.
I built and operated the delivery infrastructure that governed a $1.4B technology organization at Amazon. The only Principal TPM in a 3,000-person org. Twenty engineering teams. Sixty-six countries. Billions of transactions annually.
Few leaders have operated at that scale. Fewer have built the operating model 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. As the only Principal TPM in a 3,000-person organization, I held accountability for a $70M engineering organization spanning 20 teams, 11 business domains, and 66 countries, while driving program strategy across the full enterprise. The operating model I built governed the delivery of $100M in annual automation savings across a $1.4B organization.
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.
$1.4B
Technology organization governed. The operating model I built ran it.
$100M
Annual automation savings delivered. Against a $1.4B Opex base.
$268M
The largest Healthcare Enterprise Agreement in Microsoft history. A record that still stands.
12B+
Annual transactions. One platform. The infrastructure behind every corporate hire Amazon made globally.
5,000%
Platform growth scaled in under 60 days. The platform was on fire when I arrived.
I take on a limited number of fractional CTO and advisory engagements. PE firms evaluating portfolio companies are a particular focus.
Current engagement: Fractional CTO for a PE-backed healthcare technology company. 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.
