[For Hire] Remote Systems Administrator | Windows Server, AD, M365 & Networking | Portugal / EU
Hi everyone,
I’m an EU-based systems and infrastructure professional looking for fully remote sysadmin, infrastructure support or contract opportunities.
My background is in multi-tenant MSP operations, covering Windows infrastructure, endpoint management and L1–L3 technical support across multiple customer environments.
Technical stack and hands-on experience:
- Windows Server / Active Directory: AD DS, OU administration, user and group management, GPO configuration and troubleshooting, NTFS/share permissions, domain authentication and account lifecycle management.
- Core infrastructure services: DNS, DHCP, SMB file shares, print services, patch management and Windows client/server troubleshooting.
- Microsoft 365 / Entra ID: user administration, licensing, access management and identity troubleshooting in environments combining on-premises AD and cloud services.
- Networking / firewalls: TCP/IP, VLANs, routing and switching, Wi-Fi, VPN connectivity, firewall rules and network access policies. Experience with Sophos Firewall, Ubiquiti UniFi and DrayTek.
- Endpoint security / backup: Sophos Endpoint, ESET Protect and Acronis, including monitoring, troubleshooting and backup/recovery operations.
- RMM / remote operations: N-able N-central, remote troubleshooting, software deployment, patching and endpoint maintenance.
- PowerShell: scripting repetitive administrative tasks, AD operations, system information collection and Windows troubleshooting.
I’m comfortable handling incident triage, escalation, root-cause analysis, technical documentation and ongoing infrastructure maintenance. My strongest fit is a Windows-focused MSP or internal IT team needing help with daily operations, troubleshooting or project workload.
Open to: Remote employment, part-time support, freelance engagements and scoped infrastructure projects.
Time zone: Western Europe — UTC+0 / UTC+1 during daylight saving.
Communication: Proficient English.
