Top SchoolOleksii Klitovchenko is an experienced DevOps engineer with eight years focused on on-premise and cloud infrastructure, CI/CD, and maintaining high-throughput payment and advertising systems.

He has a track record of improving reliability and capacity in real-time OpenRTB platforms, including a measured 23% increase in load-balancer throughput, and has led national-level security and simulation projects that earned government certification. Based in South Kesteven, UK, he combines hands-on engineering, team leadership, and a penchant for photography—an unusual cross-discipline creativity that informs his practical, security-minded approach to complex systems.
