Administer Windows Server environments, including Active Directory, DNS, DHCP, Group Policy, IIS, and patching.
Deploy and operate infrastructure on AWS, GCP, Azure, and private cloud: VPCs, VPNs, transit gateways, load balancers, and security groups.
Build and maintain CI/CD pipelines, Infrastructure as Code (Terraform/Ansible), and containerized workloads on Kubernetes.
Manage firewalls, VPN/IPsec tunnels, DNS, and load balancers such as HAProxy, NGINX, and cloud LBs.
Set up monitoring, logging, and alerting with Prometheus, Grafana, ELK, or similar tools.
Participate in incident response and root cause analysis, and provide L2/L3 support for enterprise customers.
Document network topologies, runbooks, and standard operating procedures.
