I am a technologist with the passion for design, deployment and management of complex enterprise networks, security and data center networks. During my years in the IT industry, I have commanded a wide variety of technologies in the design and deployment of business and network solutions. My areas of expertise include security consultancy, network design, infrastructure integration, network migration, business-to-business solutions, hosting infrastructure, network management and operation etc. I can helicopter-view on a challenge to define how ultimate business goals can be met, as well as dive into the technical details of development and design processes. I emphasize on practical and theoretical aspects of network and systems architectures, with a focus on solutions that substantially improve stability, efficiency and profitability. I have performed responsibilities within Local & Regional Government, Education, Financial, Pension, PCI-DSS, Housing, Health & Care and Transport sectors.
