Az oktatóról
Ország Tamás vagyok, egészen csekély gyermekkoromban kaptam el a számítógép-fertőzést, amiből szerencsére azóta sem gyógyultam ki. Fejlesztő, rendszerszervező és üzemeltető végzettségeim vannak, belekóstoltam mindegyikbe, végül az utóbbi ízlett/ízlik a legjobban, különös tekintettel a hálózatokra, szerverrendszerek fenntartására. Sok különböző környezetben megfordultam a mindenes IT SMB-től a nagybankokig, kutatóintézettől a saját vállalkozásig. Jelenleg a Training360 oktatóközpontot erősítem rendszermérnökként, vezető oktatóként. Nem zárom ki, hogy külső szemlélő számára kockának tűnhetek, mivel munkaidőn túl is körülvesznek a számítógépek. Mondhatjuk, szabadidőmben is mindenre kíváncsi vagyok.
