Maidstone, England, United Kingdom
I'm a Senior System Engineer with 6+ years keeping hybrid infrastructure reliable for businesses that can't afford downtime. I support 400–500 users across MSP and enterprise environments, managing everything from AWS and Azure to on-prem Windows Server and Linux estates, and I'm usually the person colleagues escalate to when something's gone wrong and needs a calm, methodical fix. My day-to-day spans cloud infrastructure (AWS, Azure, VMware, Hyper-V), identity and endpoint management (Active Directory, Microsoft Entra ID, Intune), and Microsoft 365 administration, including tenant migrations I've delivered with zero data loss. I've introduced Terraform and Ansible to cut down manual provisioning work, built proactive monitoring with PRTG and LogicMonitor that catches problems before they become tickets, and maintained a 95%+ customer satisfaction rating over three years while handling 250–300 tickets a month under ITIL 4 process. I'm equally comfortable architecting infrastructure and being the senior escalation point on a live incident, troubleshooting through to root cause and explaining what happened in plain language to non-technical stakeholders. Tools and platforms I work with regularly: AWS, Azure, VMware, Hyper-V, Linux (RHEL/CentOS/Ubuntu), Windows Server, Terraform, Ansible, PowerShell, Active Directory, Microsoft Entra ID, Intune, Microsoft 365, ServiceNow, PRTG, LogicMonitor, Fortinet, Veeam, Acronis. Based in the UK, open to Senior System Engineer, Infrastructure Engineer, Cloud Engineer, and Senior IT Support roles — on-site, hybrid, or remote.
• Provide senior-level support across hybrid AWS/Azure infrastructure for multiple managed service clients, acting as escalation point for complex incidents and changes. • Lead Terraform and Ansible adoption for server provisioning and configuration management, cutting routine deployment time by roughly a third and standardising builds across client environments. • Administer 60+ Linux servers (RHEL, Ubuntu, CentOS) and associated AWS workloads (EC2, S3, IAM, VPC), applying RBAC and Zero Trust principles to maintain consistent uptime with no SLA breaches. • Manage Azure VM, networking, and firewall configuration across multiple client tenants; administer Microsoft 365, Intune and Entra ID for 500+ users and devices, reducing identity-related incidents through tighter conditional access and endpoint compliance policies. • Set up proactive monitoring (PRTG, LogicMonitor) with alerting workflows that shortened mean incident response time and reduced after-hours escalations. • Manage VMware vSphere and Hyper-V estates (100+ VMs), covering patching, capacity planning and DR testing. • Own day-to-day Connectwise Manage ticket queue (200+ tickets/month) within ITIL 4 SLAs, sustaining a 95%+ customer satisfaction rating over three consecutive years.
