I dig under the surface until the magic stops being magic.

I help with scripts, integrations, logs, SQL diagnostics, Linux issues, workflow automation, and small internal tools. Alongside that work, I write hands-on notes as I study networking, Kubernetes, web security, and cloud.

/now — May 2026

  • Studying for the CKA — targeting this quarter
  • Building bottom-up labs for networking, web, Linux internals, and Kubernetes
  • Publishing practical notes from tiny labs: packets, logs, scripts, APIs, and systems
  • Taking small fixed-scope freelance work around troubleshooting, automation, and integrations

This page updates roughly monthly. Inspired by Derek Sivers' /now page idea.

about

Alex Susanu

I'm Alex — UK-based, working as a support engineer and taking on practical freelance work around technical troubleshooting, automation, integrations, scripts, logs, SQL, and small internal tools.

In parallel, I'm building a bottom-up path through networking, Linux, Kubernetes, web security, and cloud. My approach is simple: build tiny labs, break them, prove what happened, and write down the parts that finally clicked.

The useful bit is proof: commands, logs, packet captures, diagrams, and notes that show what actually happened rather than just repeating definitions.

building

Small, focused projects and labs — scripts, integrations, Linux networking, web, Kubernetes, and systems debugging. Each one is something I built, broke, and explained.
