A bit about me

I'm a Computer Engineering student at the University of Ioannina who has complemented my studies with real-world experience as an IT Support Technician and IT Systems Administrator Intern.

At the University of Ioannina, I installed and maintained systems and built software tools for a diverse academic community. More recently, at Masoutis S.A., I worked with enterprise infrastructure — implementing Zabbix monitoring with over 22,000 sensors, configuring SNMP for proactive maintenance, and managing VLANs on Cisco RV and HPE Aruba CX 6000 switches.

I now aspire to grow as a Systems Engineer or Systems Administrator, focusing on designing, securing, and optimizing infrastructures that support organizational efficiency and scalability.
