About this site

First things first.
So, netman ≠ Man of Networks but rather -> NETwork MANager.

I’m Stelio E. Efstathiou, network Architect, engineer, SOC automator and systems engineer who believes that infrastructure should speak for itself, stable, minimal, resilient.

I’ve spent 2+ decades designing, deploying, and maintaining networks that don’t flinch. From high-availability Tier 1 Cerrier Provider and ISP backbones to low-footprint AI-powered SOC and NOC, my work combines precision, practical obsession, and ruthless simplicity.

Netman.Engineer is where I present selected projects, labs, and PoCs, all designed with one principle:

Designs don’t lie.

Whether it’s SOC/NOC/SysOps/CloudOps automations (AI-powered), routing logic, or bash scripts, this site isn’t about marketing fluff.
It’s about what works, what survives, and what scales.
