About me

The brand

Michiel Praamsma

Versatile freelance IT professional

Backed by more than 15 years of experience and a backpack of solid knowledge in the field of complex Microsoft infrastructures I am able to fullfill positions in large organizations in the field of infrastructure migrations, administration and design. I excel in a project setting focussing on Active Directory, Windows Server administration automation, high-level design and infrastructure component migrations. I can easily switch between high-level and detail-level overview and have no problem explaining technical complex matter to non-technical people.

When your organization is determined to bring the IT department to the next level, please do not hesitate to contact me.
