I help organizations design, develop and operate secure, resilient and efficient IT environments — from strategy and governance, through infrastructure and cloud, to remote managed operations and complex project delivery.

For more than three decades, I have delivered initiatives across the full lifecycle of IT services and environments: from needs analysis, architecture and solution selection through implementation, migration and stabilization to operations, security and continuous development.
I have worked on both the customer and supplier sides. This enables me to balance business requirements, technical capability, risk, budget and operational reality.
My experience spans banking, manufacturing, energy, public administration and global enterprise environments. I support executives, IT teams and process owners in making decisions that are feasible, secure and commercially justified.
