IT Infrastructure & Operations Leader
Serhii Abakumov
I have worked in IT for over twenty years, including fifteen years leading infrastructure and technical teams. I have built and developed IT environments for diversified and international companies—from local infrastructure to systems supporting multiple offices and hundreds of employees. I have spent the past ten years at Oracle.
My primary focus is corporate IT infrastructure: servers, networks, cloud environments, identity and access management, monitoring, backup, and recovery. I combine leadership experience with hands-on engineering, and I personally design, develop, and maintain the projects presented here.
