Independent network engineer · Lisbon · Across Europe

The senior network engineer your team doesn’t have.

Your IT team handles everything except the network in depth. I design the architecture and configure it myself, from the core to the last switch — by the hour, without an integrator’s overhead.

Sound familiar?

Most conversations start with one of these.

  1. A deployment that stalled halfway and nobody can finish.
  2. Redundancy that only exists on paper: one box fails and everything goes down.
  3. A network that grew without an architecture, and now nobody understands it.
  4. Work done badly by whoever installed it — and your team is paying for it.
  5. An integrator quote that seems out of proportion to what you need.
  6. Outages that come and go, and nobody can say why.
  7. A firewall rulebase no one dares to touch.
  8. An SD-Access or ACI rollout that never got finished.

If one of these is yours, that’s the work I do.

What I work on

One engineer, the whole network.

Problems rarely stay inside one layer. Because I work across all of them, the fix for your firewall doesn’t break your routing.

Details and typical work

How I work

A senior engineer, without the integrator.

  • From architecture to command line

    The person who designs your network is the person who configures it. Nothing gets lost between a consultant’s slides and a technician’s keyboard.

  • Tested in a lab before it touches your network

    Changes and migrations are rehearsed first in a lab with real vendor images, so the maintenance window holds no surprises.

  • Independent

    I don’t sell boxes or licences, and there’s no integrator margin on top. You pay for engineering hours, and the recommendation is the one that fits your network.

  • Your part-time network engineer

    After the first problem, many teams keep a monthly bank of hours: a senior engineer on call for changes, questions and escalations, without hiring one.

  • Remote by default, in person when it helps

    Day-to-day work happens over secure access that you control and can revoke at any time: faster, and no travel costs. Consulting, architecture and engineering all work remotely. If you’re in the Lisbon area and prefer to sit down for a kick-off, a workshop or a design review, I’m happy to meet in person.

  • Every change documented

    Diagrams, configuration notes and the reasoning behind decisions, so your team is never dependent on me.
