Systems Administrator · Cloud · Automation
Hey! I’m Jalin, a Systems Administrator based in Cambridge, MA. For 6+ years I’ve kept Windows Server, Linux, and endpoint environments running across legal services, pharmaceutical software, and managed IT services. I like automating the boring parts, and I write up what I build along the way.
Servers & virtualization
Windows Server 2016–2022, Linux (Ubuntu, Debian, Red Hat), Hyper-V, VM migrations and hypervisor upgrades.
Identity & Microsoft 365
Active Directory, Entra ID, Group Policy, RBAC, Exchange Online, SharePoint/OneDrive, and Teams.
Endpoints & security
Intune compliance, Windows Autopilot, endpoint hardening, patching, and least-privilege access.
Automation
PowerShell tooling for diagnostics, AD lifecycle, and reporting. Ansible, Terraform, and Docker.
Networking
Switch configuration, VLANs, firewall rules, DNS, DHCP, and on-site network deployments.
Process
Jira, Confluence, ConnectWise, ServiceNow, and KB and SOP authoring.
