What I'm looking for

I'm looking for a junior IT infrastructure role where I can contribute to systems, networks, and user support while growing in cloud and automation.

I've supported enterprise IT operations during a six-month internship at HP CDS, following technical procedures, resolving incidents methodically, and documenting system checks.

I'm trained in Network Systems Administration (ASIR), with hands-on work across Windows Server, Active Directory, Linux, virtualization, networking, and troubleshooting. My technical projects include configuring IP addressing, DHCP, ACLs, routing and switching; administering users, permissions and GPOs; and deploying multi-node Linux environments with MariaDB/Galera.

I'm especially interested in infrastructure, cloud, and automation, and bring C1 English, fast learning, and a collaborative approach to IT support.
