Expertise
From Strategy to System — Without Losing Either
Complex technology challenges don't stay in their lane. They start as business decisions, surface as architecture problems, and land on teams that need leadership. I work across all three — as an advisor, an architect, and when necessary, an embedded leader.
Strategic Advisory
When the decision is too consequential for guesswork
Board-level guidance on technology strategy, transformation programs, and decisions where technical and commercial logic must align. I've led these from both sides of the table.
- Technology strategy and multi-year roadmaps
- Digital and AI transformation program design
- M&A due diligence — buyer and seller side
- Organizational restructuring and capability design
Architecture & Design
Practical designs informed by delivery reality
Hands-on architecture for complex systems. Enterprise architecture, security architecture, cloud-native design, AI system integration — grounded in current implementation experience, not frameworks alone.
- Enterprise and security architecture
- Threat modeling workshops and capability building
- Cloud-native and AI/ML system design
- Architecture reviews and technical due diligence
Technology Leadership
Executive capability — when and as long as you need it
Embedded leadership for organizations navigating transitions, filling critical gaps, or building capability that doesn't yet exist internally.
- Interim or fractional CTO / CISO
- Transformation program leadership
- Troubled program rescue
- Team structure and organizational design
- Technology capability development

How Engagements Work
Every engagement starts with understanding the actual problem, not fitting your situation into a predefined package.
Advisory & Reviews
Days to weeks
Architecture reviews, strategy validation, expert assessment, due diligence support. Scoped, fast, and designed to produce actionable output.
Sustained Engagement
3–12 months
Architecture delivery or transformation leadership requiring consistent senior involvement over time. Embedded, not remote-advisory.
Fractional Executive
Continuous
Part-time CTO, CISO, or architecture leadership. Executive capability and accountability without the full-time commitment.
