I'm Dr. Francis Kagai, a technologist specialising in resilient communications, secure distributed systems, and satellite-enabled connectivity, with international experience spanning research, engineering, and high-risk operational environments.

My work centers on secure architecture design and the intelligent automation of systems that maintain operational continuity when infrastructure is degraded, bandwidth is constrained, or connectivity is intermittent. I design and secure communication platforms, remote and satellite-enabled networks, and critical infrastructure systems — with a focus on robustness, autonomy, and real-world deployability.

That operational background sits at the intersection of three things I teach here on Udemy: core networking (CCNA), network automation at scale (CCNP Automation), and the emerging discipline of autonomous AI agents (NVIDIA NCP-AAI). The same principles that keep a satellite network running without constant human oversight — fault tolerance, autonomous decision-making, graceful degradation — are exactly what modern network automation and agentic AI systems are built on.

My courses are built for practitioners: engineers and technologists who want certification-ready knowledge grounded in how these systems actually behave in the field, not just in theory. Whether you're starting with networking fundamentals or moving into AI-driven automation, my goal is to give you the conceptual foundation and practical confidence to pass your certification and apply it in real environments.
