About me
As a freelance IT professional I have devoted myself mostly to programming in my 30-year career. Having started programming in Assembler, C, Clipper, and Pascal I have been specialized in creating websites in Drupal for several years now.Additionally, I have gained extensive knowledge in planning and administration of large, often heterogeneous networks. From the experience gained – especially in the Cisco environment – I still benefit up to today when administrating and hedging website service.
