ML platforms

ML platforms your team stops thinking about

An ML platform is working when scientists ship models without filing tickets and the cloud bill makes sense. I build them on Kubernetes with Terraform and GitOps, small enough that your team can run them after I leave.

A capacity-aware scheduler: GPU jobs only fit the GPU pool, and nothing is placed on a node without room for it. Illustrative.

What goes into one

  • GPU and CPU node pools with autoscaling.
  • Queues and capacity-aware scheduling, so a training job waits for room instead of evicting someone else's.
  • Experiment tracking and a model registry (MLflow), with pipelines in Airflow or Kubeflow.
  • GitOps with Argo CD or Flux, and Terraform for the cloud underneath.
  • Observability: Prometheus, Grafana, Loki and OpenTelemetry.
  • Cost controls: requests and limits that match real use, idle capacity that goes away, and storage tiers for data nobody reads.

I start from what people run each week, not from a reference architecture. A team that trains twice a month on one GPU node needs a different platform from one serving models to production traffic. Build the second for the first and that team ends up maintaining controllers nobody uses.

Where I've done it

At a global energy company I took model deployment from weeks to hours with Kubernetes, Kubeflow and MLflow, and cut infrastructure costs by 40% with a Google Cloud and Kubernetes redesign.

For clients, we moved a data-science team from Azure VMs to Kubernetes and MLflow on two clouds, grew an online business to 20 million daily users on EKS, took a $2M monthly cloud bill to $400K at the same traffic, and planned launch-day capacity for a checkout API.

On my own time I run CI for a product on a five-node BuildKit fleet in bare-metal k3s, which is where I try scheduling and caching ideas before I suggest them to anyone else.

Case studies and write-ups

Questions people ask

GKE, EKS or something else?

Whatever you're on. I've built on GKE, EKS, AKS and bare-metal k3s.

Can you move us off hand-built VMs?

Yes. One client moved a data-science team from Azure VMs to Kubernetes and MLflow on two clouds; see the case study.

Who runs it afterwards?

Your team. Everything is in Git, with dashboards and a runbook.
