Infrastructure and security, treated as one job.

I harden Kubernetes and cloud environments, design Zero Trust architectures, and build CI/CD pipelines with security gates built in rather than bolted on. Currently I keep payment infrastructure reliable as a DevOps / Product Reliability Engineer at Hubtel in Accra.

Alongside engineering, I train. At JOMACS IT Solutions I teach Kubernetes end to end: foundations, workloads, cluster security, network policies, Helm, Kustomize and cluster setup. I also practise digital forensics through the Hive Consult Digital Forensics Training Programme, producing formal investigative reports on disk, browser, memory and device evidence.

Essential Linux Commands: The Toolkit Every Engineer Uses DailyEpisodes 01 and 02 built the mental model — the Unix philosophy, the filesystem, inodes, permissions. Now we build the muscle memory. 24 Jun 2026 The Linux Filesystem: Everything Is a File, and Files Are EverythingIn Episode 01 we introduced the Unix philosophy and got our first terminal session running. We mentioned one idea in passing that deserves its own episode: everything is a file . 21 Jun 2026 Introduction to Linux: What It Is, Why It Rules the World, and How to Think Like a Linux EngineerHere is a fact that surprises most people outside of tech: you have used Linux today. Almost certainly multiple times. 18 Jun 2026
