Filippos Argyropoulos Ioannou
@filipargyropoulos
IT support specialist trained by Microsoft who administered Windows Server hybrid infrastructure and Microsoft 365.
CzechiaWhat I'm looking for
I've spent five years in the unglamorous middle of complex operations — the HIPAA queues, the government document escalations, the 200-ticket backlogs — while quietly getting certified in the infrastructure that powers it all (AZ-800/801, hybrid Azure, Windows Server).
My background is a bit of an odd mix: frontline support, community management at scale, crypto infrastructure research, and Microsoft hybrid certs. But that mix tends to be useful in places where the technical and the human have to meet — which, increasingly, is everywhere.
Experience
Work history, roles, and key accomplishments
Answer traveller questions in Greek and English over email and live chat for a ferry-booking platform, consistently meeting SLA and quality targets. Resolve booking, payment, refund, and cancellation issues across Intercom and operator-specific platforms.

Walked customers through government travel and legal documentation requirements and compliance rules. Maintained quality across simultaneous email, phone, chat, and ticketing queues at high volume.
