Senior Cloud Architect II

☸️ Battle-tested Kubernetes Operator 🤫

United Kingdom

I've probably debugged a Kubernetes issue in more time zones than I care to count. Based in London, I help engineering teams across EMEA get their clusters to behave — and actually understand why they misbehaved in the first place.

I write, speak, and guest on podcasts about all things cloud-native. Away from the terminal: I enjoy cooking almost as much as simplifying overly complex systems.

What my customers say

GCP status pages are too slow to update. Yet another case that wouldn't have been a case if Google admitted to incidents quicker!

Kubernetes Production Health Assessment
How healthy is your cluster, really?
Most engineering teams assume their cluster is healthy because it's running.
Running and healthy are not the same thing.
We've reviewed clusters for years. The ones that hold up under pressure aren't the most complex — they're the ones that quietly have the fundamentals right. This assessment tells you exactly where yours stands across the areas that matter most.

Insights by human experts

What customers are saying

  • Assertive input for design and business requirement of evaluation. Quite good assistance from Nikhil.

    Today

  • response times were slow

    Today

  • Diego gave clear advice, was able to share some information about the Dataform roadmap that we wouldn't have otherwise had access to, and helped to escalate our Google internal ticket.

    Today

  • Diegos persistence to challenge Google support for their lackluster answers was outstanding.

    Today

  • Nikhil was patient with me when the scope changed, which I really appreciate!

    Today

  • Not great, I was directed here by David Spenard after asking in the chat whether I should go to Google only then to be told to go to Google after all. Kind of a waste of a day

    Today

  • I would like to take a moment to appreciate one of the best customer support experiences I have ever had. What truly stood out was the incredible level of ownership, dedication, and genuine willingness to help demonstrated by the support agent - Houssem Sabbegh. At no point did it feel like he was simply handling a customer’s issue as part of his job. Instead, he approached the problem as if it were his own, taking complete responsibility and showing a sincere commitment to getting it resolved. He patiently stayed on the call with us for nearly two hours, thoroughly investigating the issue, exploring possible solutions, and ensuring that every concern was addressed. Not once did he seem rushed, frustrated, or eager to close the conversation. His sole focus was on making sure that the issue was completely resolved and that we were satisfied with the outcome. This level of patience, accountability, professionalism, and customer-centric attitude is extremely rare and deserves special recognition. It is one thing to provide technical assistance, but it is something entirely different to genuinely care about a customer’s problem and remain committed until it is resolved. What impressed me the most was that he never treated our issue as just another support ticket. He made us feel that resolving our problem was just as important to him as it was to us. That kind of ownership and empathy makes an enormous difference in the overall customer experience. I have interacted with many customer support teams over the years, but this experience genuinely stands out as one of the absolute best. If every customer support professional demonstrated even a fraction of this level of dedication and ownership, customer service experiences would be significantly better everywhere. I sincerely appreciate his efforts and would strongly recommend that his exceptional work be acknowledged and recognized by the team. He is a fantastic example of what outstanding customer support should look like. A huge thank you for going above and beyond. Your dedication, patience, and commitment truly made a difference, and your efforts did not go unnoticed!

    Today

  • Super fast and good help on this!

    Today

  • The common belief among my team is that Zvi from IT Support is a god.

    Today

  • Great service, super nice people and well prepared as well

    Today

  • Thanks Alex for the assistance

    Today

  • Isidoro was very helpful in getting what I needed from AWS quickly

    Today

  • Houssem was fast and knowledgeable. He presented options and recommendations, and most importantly we resolved the incident in a timely manner. Couldn't have asked for a better response! Thank you Houssem!
