Khadirullah Mohammad

DevOps & Cloud Engineer

I build CI/CD pipelines, manage cloud infrastructure, and automate everything I can with Docker, Kubernetes, Terraform, and AWS. Recently I built uptime-checker, a six-service app with a GitHub Actions DevSecOps pipeline and ArgoCD deploys, and a 3-node Kubernetes cluster that comes up from a single terraform apply. I also built an AI-powered incident correlation tool that JOINs data across GitHub, Sentry, and Slack using cross-source SQL.

This blog is where I document it all, with hands-on tutorials and notes from problems I’ve actually solved.

💼 I’m actively looking for DevOps & Cloud Engineering roles. Get in touch.

A deep dive into building a fully automated local Kubernetes cluster with Terraform and QEMU/KVM. One command provisions 3 VMs, installs Kubernetes via kubeadm, deploys Calico CNI, and joins workers automatically (no manual SSH required). Includes a detailed breakdown of the Terraform libvirt provider 0.8→0.9 rewrite and what breaking schema changes mean for your infrastructure code.

Automating social media preview images (Open Graph) using SVGs is incredibly powerful. But when I tried to automate SVG-to-WebP conversions on my Linux server, I discovered that standard command-line tools like Inkscape and ImageMagick handle browser-oriented SVGs very differently from Chrome.
