    Hosting triage CLI for the support desk

    The same hosting problems kept coming back, so I wrote a Python tool that checked a client's DNS, email and website in one pass and printed the fix, ready to paste into the chat. About 10 consultants ended up using it, and it's what got me noticed when I applied to Nclose.Case study →

How I work

  • Phased Ubuntu to Debian migration of log collectors across three offices

    Change safely. Every change has a way back.

    Moving a financial asset manager's log collectors from Ubuntu to Debian across three offices, I used an IP swap script with a health check and a timed auto-revert, which kept disruption to a minimum.

  • Applying an updated ISM policy to existing OpenSearch indices

    Find the root cause. I don't stop at the symptom.

    The team kept deleting old indices by hand on the compliance clusters. I found why: updated ISM policies were never applied to the indices that already existed. I aligned them with the change policy API on every compliance cluster.

  • OpenSearch diagnostics and capacity forecasting tooling

    Automate the second time. If I've done it twice, I script it.

    Diagnosing an OpenSearch issue used to be a manual, multi-step investigation. My Python triage tooling takes it from about 45 minutes to about two minutes and warns us before a cluster runs out of capacity.
