About trainer

Jakub Hajek
CEO, technical consultant
I’ve been working in IT for over 20 years as a system administrator, delivery manager, team leader and a project coordinator. On a daily basis, I run Cometari and try to juggle between being an entrepreneur, manager and an expert. I use my technical and business experience in my company. I carry out projects mainly in the area of infrastructure, containers and solutions that support these technologies. I believe that the best way of cooperating is one in which a team delivers solutions that provide the customer with measurable values rather than generate more problems. I am a firm advocate of consistent and persistent work. That’s why, every day I do technical work in areas such as Docker, Cloud Native, Kubernetes, DevOps and Elastic Stack. I am also a Certified Kubernetes Administrator (CKA). I make professionalism and relationship with people – both with my team and customers - our priority at Cometari. That’s why, as a leader I give my team a high level of trust and work space and what I receive in return is the best solutions for my customers. Privately, I am a proud father of my son Julian and an amateur, though enthusiastic sportsman.
