Bio
Branson Matheson
Ondrej is an great network architect, well versed in security, systems and engineering and a true pleasure to work with. Ondrej and I had the opportunity to develop a plan for the combination of two complex environments and spent considerable time working out minute technical details to allow the integration to succeed. His command of network architecture and constant vigilance of the security aspects of the environment allowed us to develop a model which met all the stakeholder requirements and goals. I am very impressed with his use of documentation tools to track the complex environment and maintain system integrity. I also worked with many of his team and they reflected his drive and competence. Ondrej is a great associate to work with, both onsite and digitally. He's comfortable in front of an audience, explains technical details with ease and communicates at different levels to meet individual needs. Ondrej would be a true asset to any company seeking a well-qualified and well-rounded associate who can lead a team, design and maintain complex architecture with networking, integrated and secure systems.
