I build platforms that stay calm under pressure.

I’m Vishnu, a DevOps and Platform Lead in Singapore. For more than nine years, I’ve helped teams design, automate, and operate infrastructure across Kubernetes, public cloud, private cloud, and GPU platforms.

About

I work on systems that teams depend on.

Most of my work is for telecom, government, media, and enterprise teams in APAC. I have built and upgraded Kubernetes platforms, moved workloads to the cloud, worked in air-gapped environments, and set up infrastructure for AI inference.

I prefer practical engineering: make the design clear, automate repeatable work, document what matters, and leave the system easier to operate than I found it.

Writing

Why I write

I use this site to keep practical notes on infrastructure work and local AI experiments. Writing things down helps me remember what worked, and it may save someone else some time.
