about.

Hi, I'm Shivam Kumar (I write as cvam). I'm a DevOps engineer with 2+ years of experience running infrastructure, and I'm currently studying for a master's in AI/ML. cvam.sight is the long-form notebook I keep while I learn: what I read, what I build, and what broke along the way.

What you'll find here

  • DevOps & cloud-native — Kubernetes, CI/CD, observability, cost control, and a full Kubestronaut study path.
  • Postgres — queries, indexing, replication and performance.
  • Security — threat models, hardening, post-quantum cryptography, conference talks and social engineering.
  • AI / ML — course notes, research-paper explainers (Paper Juice), and how modern LLM systems are built.
  • Reference — cheat sheets, debugging guides and curated tool lists for day-to-day work.

How articles are written

Most articles are long on purpose: they start from a question I actually had, explain the background and the why, then walk through commands, diagrams and failure modes. I use AI tools to help with drafting and research, and I'm responsible for everything that's published. Where an article summarises someone else's book, paper or talk, it says so and links to the original. Please read the source if you want the full argument.
