Chimbu Chinnadurai
Senior Cloud Architect II
☸️ Battle-tested Kubernetes Operator 🤫
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 about it, speak about it, and guest on podcasts about it.

I submitted a request for some BigQuery / Billing support late yesterday and Sayle made an initial response very quickly and we had an exchange to run one test and he was able to narrow down the problem domain successfully. He then engaged with his team and I now have a working solution in place in less than 24 hours. Great Support.

I wanted to give a huge shoutout to Houssem. Having worked on several tickets with Doit over the years, I found this latest experience to be on another level entirely. While our past interactions have been good, Houssem’s work etiquette and genuine care for the customer really stood out. He managed to make the process feel seamless and professional, even while we were dealing with a major issue.
