"Strategy without tactics is the slowest route to victory. Tactics without strategy is the noise before defeat."
— Sun Tzu
I operate at the intersection of business strategy, technology architecture, security, and executive leadership, with hands-on execution capability. Twenty-five years of building, leading, and transforming technology organizations across Europe. Now available for engagements in the Middle East.
What I Bring
Three Pillars
Effective technology leadership requires integration across strategy, people, and technical execution, not switching between them, but applying all three simultaneously.
Business
The Strategist
I think in P&L, market dynamics, and multi-year horizons. Technology decisions connect to business outcomes.
- Transformation program leadership
- M&A due diligence (buyer & seller)
- Commercial strategy & business development
People
The Leader
Building organizations that deliver beyond direct involvement. International teams, C-level collaboration.
- Regional security organizations across multiple countries
- Organization design from ground up
- Direct CEO reporting relationships
Code
The Technologist
I still build production systems. Current hands-on experience keeps every other capability grounded.
- Full-stack: Vue.js, NestJS, Python, Go
- Cloud-native: AWS, Kubernetes, Terraform
- Graph databases, AI/ML integration

Let's Solve Something Complex
Whether it's a transformation program, an architecture challenge, or a leadership gap, I work with organizations facing problems that span strategy, technology, and execution.
