Serhiy was my lifeline for technical expertise on a couple projects installing Exalogic (predecessor to the Oracle Private Cloud Machine.) His hands-on experiences in virtualization, storage, network, OS, load balancer and middleware are superb. Going beyond his duty, he patiently listened to my challenges and, on multiple occasions, gave me brilliant design ideas and proven solutions. A great team player for anybody's team!
