Hey there — thanks for stopping by!

I’m Loan Dumenoir, a 23-year-old engineer who works where networking meets software.

How did I end up here?

  • It began in high-school electronics labs, soldering boards and writing tiny C routines to chat over I²C and CAN.
  • Curiosity pushed me toward wireless home-automation (ZigBee / LoRa) and, inevitably, full-blown IP. Wanting to grasp what we casually call “the Internet” — and how to run routers and switches not just in an enterprise closet but at service-provider scale — I became hooked on how packets travel, dissecting protocols such as BGP, MPLS and RSTP.
  • I also spent evenings on Root-Me. Far from a CTF prodigy, I gained a lot by dismantling OWASP Top 10 labs and experimenting with buffer-overflows—seeing how things really break at the lowest level and how to avoid those pitfalls.

After a few internships and a graduation project, I moved from traditional IT ops to what we now call NetDevOps — bringing CI/CD discipline, version control and testing to routers, firewalls and data-centre fabrics.

Why this blog?

French industry is still catching up on NetDevOps. I’d like to help fill the gap by sharing:

  • hands-on guides;
  • real-world lessons learned — the misconfig stories as well as the shiny diagrams;
  • a healthy dose of troubleshooting notes so Google can index them for the next unlucky soul.

If you’re into automating networks rather than clicking through GUIs, you’ll feel at home.

Off duty

Ice-skating, swimming and regular workouts keep my brain functional.
When I’m not at the rink or the pool you’ll find me spoiling two rabbits and an unreasonable number of houseplants. 🌿
