Rockstar🎓
Top SchoolLeo Fleskes is a Network Automation Engineer with a decade of experience building and operationalizing automated network solutions across enterprise environments. He has progressed from a dual-study trainee to senior consulting roles at Network to Code and now leads automation efforts at DB Systel, working with Cisco, FortiNet and Check Point platforms. Technically hands-on, he contributes to open-source projects like Nautobot—improving backend testing, GraphQL integration, and dynamic group functionality for a widely used network automation platform. Leo blends software engineering rigor from a Computer Science background with practical network operations experience, enabling repeatable, auditable automation at scale. Colleagues rely on him to translate complex network requirements into testable, production-ready automation. A subtle strength is his focus on strengthening testing infrastructure, which reduces risk when deploying automated workflows in critical networks.
