· TurboRegime Creator/Developer“I didn’t come from Wall Street. I came from the defense industry.”
For 39 years I designed and managed the development of sophisticated real-time, deterministic, low-latency systems for the defense industry. I have supported many Air Force programs including the F-35 Joint Strike Fighter, B-2 Spirit stealth bomber, F-15 Eagle fighter, UK E-2D AWACS and others. I even had a very small role supporting NASA in the development of James Webb Telescope. When you’re building systems that have to work in the most unforgiving environments imaginable, you learn to think differently about discipline, risk management and reliability. It turns out those systems-thinking skills translate directly very well to the markets.

The Beginning
My systematic trading journey didn’t start with TurboRegime. It started in the 2000s with a program I designed called Flipper.
Flipper was a trading bot that sampled US market activity between international market close and the US 4pm close, detected a statistically significant edge in international mutual funds, and automatically dialed up through a phone modem to place trades in multiple 401(k)s. No emotion. No hesitation. Just signal and execution.
It averaged more than 70% annually during the period we ran it.
My longtime friend and engineering colleague, Miguel Diaz, was my collaborator and sounding board through that entire period — and has been ever since. Between us we bring 80 years of combined engineering experience and market thinking dating back to the 1980s.
The Evolution
As markets evolved, so did our approach. When Flipper’s edge closed, we kept refining the thinking. How do you systematically detect regime changes in the market? How do you protect capital during stress and accelerate into recoveries? How do you remove emotion from the equation entirely?
Those questions drove 25+ years of automated, rules-based trading research.
Along the way we learned some memorable lessons in system reliability. In the early 2000s, sitting in meetings at Honeywell, we needed a way to know whether our bot was alive and had executed trades. Our solution was pure engineering — we encoded the signal into our pagers (yes, well before Blackberry or iPhones).
If neither pager went off, it was time to find a computer.
That’s how engineers solve problems.
TurboRegime
TurboRegime is the culmination of four decades of parallel experience in systems engineering, bot development and market research.
It is a regime-based allocation strategy that dynamically rotates between three states — RiskOff, RiskOn, and RiskOn++ (Turbo Mode) — based on systematic signal detection. It is not always leveraged. It uses leverage selectively, when conditions historically support it. And it moves to defense when they don’t.
The strategy has been backtested across 17+ years of market history including the 2008 financial crisis, multiple corrections, COVID, and the 2025 tariff shock. It has been designed to be transparent — the bad years are shown alongside the good ones, because that’s the only honest way to present a strategy.
Live trading began April 1st, 2026. The track record and trade history is available on the Trades page.
The Philosophy
I built TurboRegime the same way I built systems in the defense industry — with discipline, rigor, and zero tolerance for discretionary decisions that introduce human error.
A Personal Note
I spent my entire career building systems for others. TurboRegime is something I built for myself — and ultimately for my friends and family. It is designed as a simple way to generate good returns that compound over time, protect capital when markets get difficult, and require minimal ongoing attention.
The whole point of a good bot is that it runs without you. TurboRegime is fully automated for me, and I've provided the necessary tools should you want to follow along.
For me, that means more time on the golf course. For you, it might mean something different. But the goal is the same — a systematic, disciplined approach to the market that works while you live your life.
That’s what TurboRegime is built for.
