🎯 Milestone-Driven Learning Paths

Choose your engineering journey in AI & Hyperscale Infrastructure Architecture, Network Site Reliability Engineering (SRE), Cybersecurity & DevSecOps, NetDevOps & Automation, Low-Latency Financial Engineering, or Technical Program Management (TPM).

Every learning path is structured in progressive milestone stages backed by executable containerlab topologies, automated guided runners (./run.sh --guided), and live verification tests.

🚀 How Every Path is Executed

  1. Step-by-Step Curriculum: Read the mental model, protocol mechanics, and failure modes in the portal.
  2. Automated Guided Runner: Launch ./run.sh --guided inside the lab folder on macOS (OrbStack) or Linux (Docker).
  3. Inspect or Type: Preview configs or apply them manually using the provided syntax.
  4. Instant Verification Gates: Run automated verifier scripts that assert routing tables, forwarding states, and end-to-end ping reachability.
