DevOps Engineer & Linux Administrator

Zkušený inženýr pro Linux a DevOps. Více než 15 let zkušeností s Linuxem. Poslední téměř 3 roky pracuje také jako DevOps inženýr. Má zkušenosti s Kubernetes, Docker, Ansible. Ve své současné pozici zastává 6 různých rolí najednou - působí jako projektový manažer, inženýr infrastruktury, provádí školení, spravuje cluster, kóduje věci v Ansible a pracuje jako architekt. Z bezpečnostních důvodů tam však dělá věci ručně. S cloudovými platformami zatím neměl možnost pracovat, ale neměl by problém se je naučit. Většinou řídí menší týmy o max. 10 lidech. Preferuje dlouhodobé projekty alespoň na rok. Angličtinu bere jako svůj mateřský jazyk. V němčině by rozuměl všemu, ale musel by se domluvit.
