N27 Network Lab

A browser-based network lab. Draw a topology, cable ports in a rack, deploy it with Containerlab and configure every device from a browser terminal.

  1. 01 Draw the topology on a canvas or in a rack
  2. 02 Cable device ports to each other
  3. 03 Deploy the saved revision with Containerlab
  4. 04 Open FRRouting or Alpine terminals in the browser
  • Containerlab
  • Next.js
  • NestJS
  • Keycloak
  • PostgreSQL
  • RabbitMQ
  • Docker Compose

The repository is private and there is no public demo. Screenshots come from local test runs with sample data.

    VXLAN fabric: SONiC control plane, VPP data plane

    Private, isolated tenant networks stretched across separate dedicated servers, with SONiC running BGP and VPP doing VXLAN, gateways and ACLs. Validated path by path.

    • 13 of 13 traffic paths passed on the two-server build
    • Tenant traffic does not depend on BGP being up
    • Every command parameterized after a lost-SSH incident
    • VPP
    • SONiC
    • FRRouting
    • BGP / EVPN
    • VXLAN
  • Professional Platform 2026

    Talos Kubernetes on KVM: a cluster runbook verified three times

    A parameterized runbook that takes a bare Rocky Linux host to a healthy three-node Talos cluster, rebuilt from scratch until every silent failure was written down.

    • 3 clean runs, each with 3/3 nodes Ready
    • Survived a real power cycle
    • 5 silent failure modes documented
    • Talos Linux
    • Kubernetes
    • talosctl
    • KVM / libvirt
    • Rocky Linux 9
  • Professional CI/CD 2025–2026

    GitLab CI/CD and Jenkins: pipelines, runners and quality gates

    How I build and run delivery pipelines, shown through a GitLab pipeline for a TypeScript monorepo, a self-hosted runner, and the Jenkins and quality-gate work around them.

    • Images tagged by commit SHA; latest moves only from the default branch
    • Services rebuild on other branches only when their code changes
    • SonarQube quality gate and Trivy threshold as blocking stages
    • GitLab CI/CD
    • GitLab Runner
    • Jenkins
    • Docker
    • Nx

How I work

A short delivery loop, with evidence at each step

  1. 01

    Decide on paper first

    Options, the choice and its trade-off are written down before the build. N27 carries 15 decision records.

    N27 decisions
  2. 02

    Automate the path

    Pipelines, pinned versions and parameterized commands: no “latest”, no hand-edited YAML, no values copied between hosts.

    CI/CD case study
  3. 03

    Prove it from the outside

    Traffic paths tested VM to VM, clusters rebuilt from the document, browser suites run against real devices.

    Fabric acceptance tests
  4. 04

    Leave a way back

    Rollback order, backup and restore drills, and incident notes sit next to the build steps.

    An incident and its fix

Experience

From network technician to platform engineer

Since 2020 in infrastructure, since 2023 in DevOps and infrastructure engineering on production platforms for a bank and a port operator.

About

A network engineer’s habits, applied to platforms

I started in 2020 as a network technician, configuring VLANs, routing and multi-site links across client sites. In 2023 I moved into DevOps and infrastructure engineering at ITGS. I started on the internal platform team, building Kubernetes clusters from scratch, running Proxmox/KVM with Ceph and working with FRRouting, BGP and VXLAN, before moving to client projects.

For a bank, I operated a highly secured on-premise Kubernetes and OpenShift platform and the GPU infrastructure behind its LLM inference services. For a port operator, I was the technical owner of the project infrastructure end to end: AWS, Kubernetes and the CI/CD pipelines across development, staging and production.

The networking years still shape how I work. I check the path before I trust the config and write the rollback next to the rollout. I have been the N2/N3 escalation point for production incidents, and I document in French and English so the next person can run what I built.
