Microsoft 365 Fundamentals
MS-900
What I bring
Front-line support experience combined with end-to-end project delivery.
User-focused
A helpdesk background means systems are configured around how people actually work, reducing support requests.
End-to-end delivery
SSO, Intune and Microsoft 365 migrations, planned, tested, deployed and documented.
Security-minded
Experience with Cisco Duo MFA and Conditional Access, currently pursuing SC-300.
Selected projects
Select a project to view the problem, approach and outcome.
01Set up single sign-on so staff use one Microsoft login for their apps
Problem
Staff kept separate passwords for each business app, and access was managed app by app.
What I did
Configured the apps as enterprise applications in Entra ID, assigned access by group, and tested with a pilot group before rollout.
Result
Users sign in once with their Microsoft account, and access is granted or removed in one place.
02Migrated a client’s email to Microsoft 365
Problem
Email lived on an older platform with limited security and admin tools.
What I did
Planned the cutover, migrated mailboxes in batches, lowered TTLs ahead of time, then switched MX and set up SPF, DKIM and DMARC.
Result
Mail was migrated to Exchange Online with authentication records in place.
04Built Intune device policies from scratch
Problem
The company had Intune available but no policies in place, so device settings and security weren’t enforced.
What I did
Designed and built the Intune policies from the ground up, including compliance policies and configuration profiles, then tested them before assigning to users and devices.
Result
Security and device settings are now defined in one place and applied consistently.
05Kept Cisco Duo sign-in protection working after Microsoft retired the old setup
Problem
Duo MFA was connected to Entra ID through custom controls, a method Microsoft is retiring.
What I did
Removed the custom controls, set up Cisco Duo as the authentication method in Entra ID, updated the Conditional Access policies and tested sign-ins.
Result
MFA runs through Duo on a supported setup, with no gap in protection for users.
06Automated routine admin tasks with PowerShell
Problem
Repeat tasks were done by hand in admin portals, one click at a time.
What I did
Wrote and tested PowerShell scripts for common Microsoft 365 and Windows admin tasks.
Result
Tasks run the same way every time and take a fraction of the time.
07Connected two offices with a secure site-to-site VPN
Problem
Branch staff used a slow remote-desktop workaround to reach files.
What I did
Built an IPsec tunnel between two WatchGuard Fireboxes with tight policies.
Result
Direct drive access; workaround retired.
08Separated guest, phone and staff traffic with VLANs
Problem
One flat network; call quality dropped at busy times.
What I did
Created VLANs, tagged trunk and access ports, set firewall interfaces.
Result
Guests isolated and dropped calls stopped.
