I am your first line of defense for issues related to Microsoft Cloud and Active Directory. Let me rescue you! If you find yourself in a predicament in which you are seeing various logged events of concern in Event Viewer or you suspect that you need an Active Directory Health Check, please get in touch. I have help many clients in which time was of the essence, in which further tampering with Active Directory would have rendered the entire forest useless. I bring over 15 years of experience to the information technology field, focusing on Microsoft Systems Administration, Microsoft 365 cloud applications (Microsoft Teams, Exchange Online, OneDrive), and telecommunications. In addition, most on-premise platforms I have deployed included the use of a hypervisor, either Microsoft Hyper-V or VMware. There is much in the way of planning for hypervisors in terms of storage, CPU, RAM, etc. I can help you with these projects as well from beginning to end. If you are looking to venture into Active Directory or Microsoft 365 cloud services you will be in good company as I have a national client base and many recommendations from happy customers.
