DevOps Engineer & Linux Administrator

S Linuxom pracuje už viac ako 8 rokov v komerčnej praxi, ale inak s ním pracuje už od strednej školy. Pracoval na aktualizáciách operačného systému, infraštruktúre, vytváraní virtuálnych strojov, čisto linuxových neaplikačných veciach a skupinách zväzkov. Má tiež základné znalosti o hardvéri. Okrem toho má skúsenosti aj s monitorovaním Zabbix a SaltStack. V budúcnosti by sa chcel okrem administrácie Linuxu venovať aj DevOps - Kubernetes, Docker, SaltStack a Ansible. V súčasnosti pracuje aj s Dockerom, má základné skúsenosti a kurz Kubernetes, rozsiahle skúsenosti so SaltStackom a niečo vie aj o Ansible. Pracoval vo veľkých tímoch o 20 ľuďoch, ako aj v menších tímoch o 3 ľuďoch. Má skúsenosti s mentorovaním mladších kolegov a nehanbí sa byť vedúcim tímu. Zaujíma sa najmä o bankovníctvo, telekomunikácie a spoločnosti, kde sa vyžaduje prísne zabezpečenie serverov. Ovláda anglický jazyk na úrovni B2 a príležitostne ho používa aj v práci.
