Fractional CTO
Embedded technical leadership on retainer. I own the hard calls on architecture, people, and delivery cadence — so your team ships instead of spins. Built for PE-backed operators, growth-stage companies, and founding teams.
For CEOs and engineering leaders navigating the shift
I've been building with agentic engineering for over a year — before it had a name. I embed with B2B SaaS teams to navigate the full transition: strategy, org design, team readiness, and hands-on execution.

The agentic engineering shift
Your competitors aren't hiring more engineers. They're building more with fewer.

Every engagement starts with where you are in the agentic engineering shift — and ends with your team operating on the other side.
Embedded technical leadership on retainer. I own the hard calls on architecture, people, and delivery cadence — so your team ships instead of spins. Built for PE-backed operators, growth-stage companies, and founding teams.
Your team knows something is broken. I find the root cause in days, fix the delivery engine in 90, and leave managers with the tools to keep it running. 300% output increase, 40% cost reduction — in a single engagement.
I build production systems with agentic workflows — the same way I built a product from a 24,000-line spec. Your team learns the patterns by shipping alongside me.
Show your board what agentic engineering changes — and what it doesn't. 2–3 hour sessions that cut through hype and end with a concrete plan your team can run the next day.
