Bio
Ivan Boichenko
I've worked with Denis for 6 years at one of the previous work places and he always showed concern and obligation to his work and company's welfare. He's proved himself as experienced system engineer and qualified specialist in DC technologies (VMware/Windows/Storage system administration). Denis is very proactive in dealing with problems and effective at anticipating potential issues. He has strong desire for continual learning and accepting new challenging projects. I was pleased to work with Denis in one team and would like to recommend him for any position that he matches.
Evgeniy Lelyakov
Denys is an exceptional system administrator who went above and beyond his expected call of duty. His knowledge and expertise always played a positive role in setting up and operating our company's growing infrastructure. He is a focused individual who knows how to move a project along. Denys is a take charge person and I hope that someday soon we will get to work together again soon
