Fractional & Interim CTO · AI Enablement

Leading-edge AI enablement for software engineering.

A hands-on technology leader helping engineering organizations turn AI from hype into shipped, production-grade software — with the security and compliance guardrails that regulated industries actually require.

Carrying forward two decades of CTO-level consulting — now focused on modern, agentic development.

How I help

Two ways to work together

The near-term opportunity is AI — adopted properly. The foundation is seasoned technology leadership. Most engagements blend the two.

Primary focus

AI enablement for software engineering

Help your teams get real value from AI in how they build software — not demos, but delivery.

  • Agentic development & multi-agent orchestration, stood up in your environment
  • AI-accelerated delivery without losing engineering rigor
  • Security & compliance review built into the loop for healthcare, finance, and other regulated work
  • Coaching your engineers on how modern, AI-native development actually works
Steady backdrop

Technology leadership

The CTO-level consulting practice, carried forward.

  • Interim & fractional CTO leadership
  • Architecture & modernization
  • Technical due diligence for investors
  • Implementation, delivery, and turnaround
Proof, not slideware

I build the tools I teach with

The methods I bring to clients are ones I develop and run myself — including open-source platforms and compliance tooling for regulated codebases.

MADO

An open-source multi-agent development orchestration platform for running AI coding agents in a disciplined, testable, trackable workflow.

Open source

Token-Weir

An open, provider-neutral usage-and-cost metering library — granular visibility into what AI-assisted development actually costs, per unit of work.

Open source

Compliance review

Adversarial security and compliance review agents (HIPAA/PHI, PCI, SOC 2) that gate AI-generated code in regulated environments. Available within an engagement.

About

Independent practice, senior bench.

S-River Services is the independent consulting practice of Mike McGonagle, carrying forward the CTO Services practice he led at BostonCIO — now sharpened around bringing modern, AI-accelerated engineering to teams that need it.

The pitch is simple: a seasoned technology leader who is hands-on with the current generation of AI development tools, and honest about where they help and where they don't.
