I have worked with IT Infrastructure Development / Delivery and IT Operations / Infrastructure for more than 23 years within the Danish financial sector. My competencies are primarily within IT Management, IT Delivery, IT Infrastructure and Operations, IT Service Management and Business Relationship- and Knowledge Management.
