Technology Leader & Fractional CTO

I’m a fractional CTO and technology strategist helping organisations navigate complex technology decisions with clarity, structure, and confidence

30 years of technology leadership together with the practical perspective of a startup founder.

Available for 15–25 hrs remote consulting per week

About

I help product and engineering leaders design pragmatic, future-ready architectures — especially when they need senior judgment without a full-time hire.

With 30 years of experience spanning Chief Architect roles, practice leadership, and platform innovation, I typically engage for architecture reviews, technical strategy, and advisory support (15–25 hours/week).

At Marlabs I led enterprise-wide architecture direction, platform modernization, and senior architecture teams. Earlier, at IGATE/Capgemini and Born Group, I conceived proprietary platforms and built high-impact practices in front-end engineering and RPA.

I now work independently while building my own technology ventures. This gives me the flexibility to bring focused, unbiased architectural judgment to organizations that need it — alongside my work on full-stack platforms for labor and agricultural markets.

My current focus is AI-native architecture, GenAI adoption, intelligent automation and the practical integration of AI into existing products and engineering organizations.

Services

Senior technical judgment, exactly when you need it.

Focused advisory engagements for startups and enterprises navigating consequential architecture and platform decisions.

When to Engage Me

Bring me in when the next technical decision carries lasting consequences.

I’m most useful at moments of growth, change, or uncertainty—when experienced, independent judgment can create clarity and reduce risk.

Perspectives

Thinking about technology—and the decisions around it.

I write about AI, software architecture, engineering practices, and the choices shaping modern organizations.

AI Strategy

Your AI Pilot Worked. Now Prove It Can Survive Production.

A successful AI demo proves that something is possible. Production proves that it is dependable. Five questions every architecture team should answer before go-live.

AI Strategy

Your AI Architecture Might Be Ready. Your Risk Posture Isn't.

AI adoption doesn't just make organizations smarter—it expands their risk surface. Every AI system introduces new attack surfaces, new reliability challenges, and potentially a new decision-maker or autonomous actor within the organization.

AI Strategy

Before You Build AI: Is Your Architecture Ready?

Most AI projects don't fail because of the model. They fail because the architecture underneath was never ready to support it. Before you build, ask the harder question: is your data, your systems, your ownership model actually ready — or are you about to find out the hard way?

AI-Native Architecture: What It Actually Means (And What It Doesn't)

AI-native architecture means designing AI systems for reliable, observable, cost-controlled operation—with clean data, feedback, evaluation, guardrails, and human oversight—not merely adding an LLM feature.

Most Companies Aren't Adopting GenAI. They're Collecting Demos.

Why most GenAI pilots fail—and how an architecture-first approach turns disconnected demos into measurable, production-ready business capabilities.
