Hey, I’m Thamjeed 👋
I’m a Linux administrator who likes going past the “it works” layer — digging into how things actually work under the hood.
Most of my work revolves around Linux systems, HPC infrastructure, and the kind of automation that makes large-scale environments actually usable. I’ve spent time with job schedulers like IBM LSF and Slurm, filesystem internals, and the plumbing that keeps compute clusters running.
What I Focus On
Linux Internals
I’m interested in how the kernel represents processes, how schedulers make decisions, and how userspace tools actually talk to the system. The /proc filesystem is one of my favorite things to explore — it’s like a window into what the kernel is actually doing.
HPC & Job Schedulers
I’ve worked with IBM LSF and Slurm in production and lab environments. Understanding how jobs get dispatched, how resources are allocated, and why things fail when they do — that’s the interesting part.
Infrastructure & Automation
Ansible, Rundeck, GitLab CI/CD, scripting — the tools that keep systems from falling over at 3 AM. I believe in automation that’s readable and maintainable, not just “works on my machine.”
Systems Programming
C, Bash, Python — the kind of code that talks directly to the OS. I enjoy writing tools that are small, focused, and actually useful.
What I Write About
Most of my posts are notes from building things, breaking things, and figuring out why things broke. They’re not clean guides — they’re more like field notes from actual work.
If something I’ve written helps you figure out a problem, that’s great. If it saves you from making the same mistake I did, even better.
