I keep the lights on — clusters, pipelines, and the boring-on-purpose infrastructure underneath. Kawaii on the outside, root on the inside.

say hisee my work

so, who is keeping the lights on

The best compliment my work ever gets is silence — no incidents, no surprises, no 3AM pages. Getting there is the interesting part, and it is most of what is on this site.

Platform · DevSecOps · SRE — physical L1/L2 through to L5/L7, across six clouds

what I actually do all day

Four things, and they all feed each other.

  • Six clouds, no snowflakes

    Cloud foundations

    Landing zones, identity, network topology and guardrails — expressed once in code, specialised per provider.

  • GitOps all the way down

    Platform & delivery

    Kubernetes people actually enjoy shipping to: progressive delivery, policy at admission, immutable nodes underneath.

  • I attack my own infra first

    Security engineering

    Signed supply chains, secrets that never touch a repo, runtime detection that pages a human and a playbook at once.

  • Alerts that arrive with the answer

    Reliability & observability

    Native histograms, honest load tests, correlated traces and logs. Every alert ships with its dashboard and runbook.

Three I am proudest of.

✿ and off the clock

There is a person under all this YAML.

She is a picky eater with a cat, an archery habit and extremely strong feelings about which Marvel character is correct.

  • Okonomiyaki

    the dish

  • Sora

    the cat

  • Scuba diving

    the escape

Got something that needs keeping alive?

Coffee, matcha, and a very tidy terraform plan accepted as payment. 🍵
