Ravindra K R

DevOps · MLOps · AIOps platform engineer. I run Kubernetes for a fleet of robots, the CI and GPU platform behind it, and the ML training and inference pipelines on top, and I fix what breaks along the way in the open-source tools we depend on.

Golden Kubestronaut (every CNCF and Linux Foundation cloud-native certification)

Open source

Contributions to the projects I operate in production, each fixing something I hit there.

I work with AI agents to find, fix and test these, so fixes reach upstream in days instead of waiting on someone to spend years learning each codebase. I review every change and stand behind it.

What I work on

  • MLOps on EKS: GPU batch and distributed training with Kueue, MultiKueue and Slurm on Kubernetes; Argo Workflows for data and inference pipelines; MLflow for experiment tracking; Karpenter spot capacity for GPUs; KubeRay pilots.
  • CI platform: GitHub Actions runners on EKS with Karpenter, container build caches and registries, benchmark and GPU test suites.
  • AIOps: LLM agents in the operations loop, from incident triage against Prometheus, Loki and Tempo to code changes that only land after mechanical checks.
