Dhananjay Patel.

DevOps Engineer · Cloud Infrastructure · India

I design and operate cloud-native infrastructure for startup teams. Currently focused on Kubernetes, AWS/GCP, GitOps, and automation that reduces cost, toil, and incident risk.

Anonymized case studies from recent platform engineering work. Client names are intentionally private.

kubernetes cost optimization

Karpenter cost optimization

Migrated Kubernetes workloads from managed NodeGroups to Karpenter NodePools with workload-specific sizing and high spot-instance usage.

gitops platform

Hub-and-Spoke GitOps platform

Consolidated separate ArgoCD instances into a Hub-and-Spoke model with ApplicationSet-driven bootstrap, TLS automation, DNS automation, and unified cluster visibility.

Reduced manual GitOps operations and standardized application delivery across dev, test, and prod environments.

autoscaling

Event-driven autoscaling

Replaced CPU/memory-only autoscaling with KEDA based on NATS queue depth, Temporal workflow count, and HTTP traffic signals.

Improved worker responsiveness and kept minimum web capacity during low-traffic windows without overprovisioning.
