Hi, I'm Saad Khan

DevOps Engineer & Linux SysAdmin — I automate, secure, and scale infrastructure.

About Me

I bridge traditional SysAdmin expertise with modern DevOps practices. Started with Linux servers in Islamabad and now build real-time AI analytics pipelines and Kubernetes clusters. From securing servers with Fail2Ban to orchestrating microservices on Kubernetes with full CI/CD — I thrive at the intersection of reliability and innovation.

Currently pursuing a Bachelor's in AIOps, which deepens my approach to intelligent infrastructure. 17+ projects, 2+ years hands-on, and 15+ tools mastered — always learning, always automating.
