I'm a remote IT support technician who keeps your team productive — the person you message when something breaks, and it just gets fixed. I handle the day-to-day helpdesk so your people aren't stuck waiting: account issues, email, devices, logins, the lot. Fast response, clear updates, problem solved. **7+ years** in IT support and systems administration, supporting **Windows and Mac** users across Microsoft 365 and cloud environments. I work as an L1/L2 helpdesk technician on monthly contracts (your outsourced IT desk) and on one-off tickets when you need something fixed now. Right now I work remotely as the **core IT systems engineer for Truetel, a Managed Service Provider based in Australia**, where I run the full MSP workflow: onboarding new clients, setting up their entire server environments from scratch, and resolving every tech issue that comes through the desk. That's real, current MSP experience supporting multiple business clients at once, not just one-off jobs. **What I handle day to day:** - **Remote Helpdesk & End-User Support (L1/L2)** — troubleshooting tickets, fast response, getting users unstuck on Windows and Mac. - **Microsoft 365 & Google Workspace** — email, accounts, licensing, Teams, SharePoint, OneDrive, password resets, MFA. - **User Onboarding & Offboarding** — new-hire setup, account provisioning, secure departures. - **Device & Endpoint Support** — Windows 10/11 and macOS, Intune/Autopilot enrollment, software installs, patching, printers. - **Active Directory & Networking** — user accounts, Group Policy, DNS, DHCP, VPN and basic network troubleshooting. - **Remote Tools** — comfortable with ConnectWise, ScreenConnect, and standard RMM/ticketing platforms. **Where I go deeper when you need it:** Windows Server, Azure & AWS administration, Microsoft 365 / Exchange email migrations, backup solutions, and security hardening (Defender, conditional access). **Why clients keep me on:** - I respond fast and follow through. One client put it simply: *"I have never seen another Upworker more passionate about helping others."* - I don't quit when things get hard. From a past client: *"The guy did NOT quit. That's the best part."* - I treat your systems like my own — quiet, stable, no surprises. If you need a dependable remote IT support technician or helpdesk engineer — hourly, part-time, or on a monthly contract — message me and tell me what's slowing your team down.
