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 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 — real tutorials and practical notes from the field.

📬 I’m actively looking for DevOps & Cloud Engineering roles — get in touch.
