Layer3.life exists because there's a gap between passing a certification and being effective on a real network.
Most network engineering education teaches you how to pass an exam. Very little of it teaches you how to think like an engineer - how to read a network, diagnose what's actually happening, and make good decisions under pressure.
I'm Dave Stabik, a Senior Network Engineer with 20+ years across enterprise, data centre, OT/SCADA, and network security environments. I've designed and troubleshot networks for mining operations, government infrastructure, and large-scale enterprise - environments where getting it wrong has real consequences.
I created Layer3.life to help network engineers close the gap between theory and practice - whether you're working toward your CCNA, trying to level up in your current role, or navigating the growing IT/OT convergence space.
