I'm Oleg Gulev, an Infrastructure & Network Engineer with experience supporting multiple customers, leading technical support, and delivering infrastructure projects.

I work best where systems, networks, and operations meet: complex escalations, production changes, technical reviews, and projects that require both hands-on depth and clear communication.
