IT Specialist in Copenhagen – Infrastructure, Cloud & Support
I am Davor Smajilovic, an IT Specialist in Copenhagen with 15+ years of professional experience across infrastructure, networking, day-to-day IT operations and hands-on technical support for Microsoft cloud technologies.
That combination is the point. When something breaks, the fault rarely announces which layer it belongs to — so being able to move between the user's device, the identity, the network, the cloud service and the server behind it is what actually shortens the path to a fix.
- 15+ years of professional IT experience
- 17 professional certifications, including Microsoft, Cisco, ITIL and Skillsoft
- Experience from ISP, university, industrial IoT and enterprise environments
- Bachelor from Technical Education Copenhagen (2016)
Troubleshooting across every layer
A slow login can be a device policy, a Conditional Access rule, a DNS problem, a saturated link or a server under pressure. I have worked on all of those layers in real environments, so I start by narrowing the layer rather than guessing at the symptom.
This cross-layer view came from working in genuinely different setups: a national ISP, a university IT department, an industrial IoT company and enterprise support at Lenovo.
- User & device: Windows, macOS, Microsoft 365 apps, Intune-managed endpoints
- Identity: Active Directory, Entra ID, MFA, Conditional Access, SSO
- Network: WAN/LAN, DNS, DHCP, IP provisioning, routers and switches
- Cloud & infrastructure: Microsoft 365, Azure, Windows Server, Linux, VMware
Infrastructure and networking
At Gigabit and Wizer I worked on the operational side of an ISP: core routers and switches, IP provisioning, DNS and DHCP, monitoring with LibreNMS, Linux servers, SQL databases and virtualisation with VMware. At the University of Copenhagen I worked with Active Directory, Group Policy, Office 365 and campus networking.
I hold Cisco CCNA alongside my Microsoft and ITIL certifications, which is the background I lean on whenever a problem turns out to be a network problem wearing a cloud costume.
Microsoft cloud and modern workplace
The largest part of my recent work has been the Microsoft stack: Microsoft 365, Azure, Microsoft Intune and Entra ID, including hybrid environments where on-premises Active Directory still carries real weight.
If Microsoft cloud is the main part of the role you are hiring for, I have written that up separately on my Microsoft Cloud Specialist page, including Intune, Entra ID and Conditional Access work.
- Microsoft 365 administration and migration
- Microsoft Intune endpoint management and compliance
- Entra ID identity, MFA and Conditional Access
- Hybrid cloud with on-premises Active Directory
IT operations, process and leadership
Technology is only half the job. I work in an ITIL-based way with incident, problem and change handled as processes rather than favours, and I have led technical support work — at Wizer I led the technical support function through the migration from Gigabit to Wizer A/S during the rebrand and stock-exchange listing.
Documentation matters to me for the unglamorous reason that it is the difference between a team that scales and a team that depends on whoever happens to be at their desk.
The expectations on support roles keep widening into identity, devices and cloud — I have written about what a modern IT support engineer needs to know today.
For the end-user support and escalation side of that work specifically, I have written it up separately on my IT Support Specialist in Copenhagen page.
Based in Copenhagen, working across Denmark and Sweden
I live and work in Copenhagen, and I work across the Øresund region in Danish, Swedish and English. Most recently I was Technology Specialist at Lenovo from April 2022 to July 2026, and I am currently open to new opportunities.
The full timeline of roles, dates and responsibilities is on my experience page, and concrete project write-ups are in my case studies.
