01 / ABOUT
I like solving infrastructure problems.
My career started in technical support and progressed into system administration and infrastructure management. I now work across Windows Server, Active Directory, Microsoft 365, Entra ID, Hyper-V, firewalls, networking, backup and operational automation.
I work best in hands-on environments where problems need to be diagnosed, tested and resolved methodically. I am comfortable researching unfamiliar issues, validating possible solutions and carrying them through to a working outcome.
I am extending that on-premises experience into Azure administration and Microsoft hybrid infrastructure, with a focus on practical cloud resource deployment, identity and operational support.
02 / REMOTE SERVICES
Focused infrastructure support for businesses, MSPs and teams that need experienced Microsoft administration without adding another full-time on-site engineer.
Windows Server & Active Directory
Windows Server, AD DS, DNS, DHCP, Group Policy, permissions and identity infrastructure support.
Hyper-V, Backup & Recovery
Hyper-V administration, VM operations, replication, Veeam backup workflows and recovery support.
Firewall, VPN & Network Support
Sophos/SonicWall administration covering NAT, VPN, access rules, VLANs and connectivity.
PowerShell Automation
PowerShell workflows for repeatable Windows, AD and Microsoft 365 administration.
MSP Overflow / Remote Infrastructure Support
Extra L2/L3 capacity for infrastructure tickets, maintenance, troubleshooting and defined projects.
03 / TECHNICAL SKILLS
Core technologies and infrastructure I have worked with.
Microsoft
Windows Server, Microsoft 365, Active Directory and identity administration.
Virtualization
Hyper-V VM deployment, clustering, replication and migration.
Networking & Security
DNS, DHCP, VLANs, NAT/VPN, firewall rules and network segmentation.
Automation
PowerShell and Task Scheduler for repeatable Windows administration and automation tasks.
Azure Administration
Expanding practical skills in Azure resource management, storage and networking while preparing for AZ-104.
04 / SELECTED PROJECTS
Selected hands-on infrastructure work and practical implementations.
01
Hyper-V & VM Deployment
Virtual machine setup & deployment
Deploy Hyper-V virtual machines based on infrastructure requirements. This includes creating a reusable master VM and deploying role-based VMs such as Domain Controller, File Server and Database Server.
02
Active Directory Deployment
Windows identity infrastructure
Built Active Directory from the ground up, including Domain Controller deployment and the supporting Windows identity environment. The work includes Active Directory, Group Policy and DNS.
03
Veeam Backup Implementation
Backup & disaster recovery
Implemented Veeam backup for virtual infrastructure and supported backup, recovery and disaster recovery requirements for the environment.
04
Sophos / SonicWall Firewall Migration
Firewall administration & security
Worked on firewall migration and administration, including NAT, VPN, access rules and network connectivity between infrastructure segments.
05
Network Segmentation
VLAN & infrastructure segmentation
Worked with VLAN-based segmentation and firewall controls to separate infrastructure and control communication between network areas.
06
PowerShell Administration & Microsoft 365 Automation
Practical scripting & administration
Worked on PowerShell workflows for two practical administration tasks: user onboarding, and Microsoft 365 license/mailbox-based group management. The onboarding workflow reduced one process from approximately 20 minutes to under 3 minutes. The second workflow checks Microsoft 365 users for license and mailbox status, compares the results with on-premises AD, and updates an AD group so only users with qualifying mailboxes remain members.
05 / POWERSHELL & AUTOMATION
Practical scripting for administration.
I use PowerShell to automate repeatable Windows, Active Directory and Microsoft 365 administration tasks. I work with existing scripts, adapt them to requirements, build new workflows, test them and troubleshoot issues until the process works as intended.
I have worked on user onboarding automation as well as a Microsoft 365 workflow that checks license and mailbox status and keeps an on-premises AD group aligned with mailbox eligibility.
01 / USER ONBOARDING
~20 min → <3 min
Reduced the time required for a user onboarding workflow through PowerShell automation.
02 / MICROSOFT 365 & AD
License + Mailbox → AD Group
Checks Microsoft 365 users for license and mailbox status, compares the results with on-premises Active Directory, and updates the appropriate AD group based on mailbox eligibility.
