Fractional CTO for SaaS Founders | Artificial Intelligence Backed by Actual Intelligence | 35+ Years Eliminating Bottlenecks & Scaling Teams

I find the point of greatest leverage — the one change that unsticks everything else — and make it happen.

What I Do Now

I work alongside CEOs and founders as a fractional CTO — owning the technology strategy, translating it into language the board can act on, and making sure the team delivers against it.

SaaS, e-commerce, HealthTech, manufacturing. Early stage through growth. The industries vary; the pattern is the same: technology should be accelerating the business, and when it isn’t, there’s usually a small number of high-leverage fixes that change the trajectory.

  • SaaS: Faster time-to-market, revenue metric instrumentation, incremental scale without rewrite risk (see detailed SaaS focus »).
  • E-commerce: Checkout and funnel performance, fulfillment visibility, promotion resilience under load.
  • Healthtech: Compliance-safe iteration, data integrity guardrails, auditable decision trails.
  • Manufacturing / Industrial: Legacy integration, workflow simplification, downtime and exception transparency.

How I Got Here

I taught myself to code in 1978 and turned pro in 1989. By the time I started my own consultancy in 1999 — serving Fortune 500 manufacturers in network security, database tuning, and infrastructure — I’d already spent a decade in production systems. That firm grew into a Managed Service Provider over eight years.

In 2007, inspired by Salesforce and early AWS, I made a bet: sold the MSP and went all-in on the cloud. That conviction — knowing when to commit and when to evolve — is what I bring to every engagement now.

The advantage of 35+ years in technology is pattern recognition. Most of what looks new is an echo of something that’s happened before — different tools, same underlying dynamics. That pattern recognition is what lets me cut through noise and find the leverage point faster than someone seeing the problem for the first time.

How I Think

I wanted a company name that captured it. After dozens of domain searches and spelunking the thesaurus, I found Agile Reasoning — the ability to adapt your thinking as the situation evolves, without losing rigor. It’s not just a company name; it’s how I operate.
