AWS EKS – managed clusters with Karpenter, ALB ingress, IAM integration, and
- optimized workloads
Azure AKS – enterprise environments with Azure AD SSO, CSI, and autoscaling
Google GKE – workload identity integration and
- optimized build pipelines
Open
Shift (on-prem/cloud) –
- on experience with 3. x and 4. x clusters, including cluster operators and lifecycle management
Rancher –
- cloud environments with centralized policy enforcement and workload monitoring
Tooling & Ecosystem
Argo Ecosystem (end-to-end Git
Ops):
Argo CD – declarative
- env deployments using the
-
- apps pattern
Argo Workflows – Kubernetes -native CI workflows for build/test/deploy
Argo Rollouts – blue/green, canary, and progressive delivery strategies with Istio
Argo Events – Git
Ops-driven event triggers for reactive pipelines
Helm (custom charts, chart libraries, deployment templating)
Kustomize – environment overlays for
-
- code
Vault +
- secrets – secure secrets delivery via Kubernetes controllers
Autoscaling & Efficiency
KEDA –
- driven autoscaling from custom metrics (Kafka, Prometheus, Rabbit
MQ, etc. )
Karpenter –
- gen cluster autoscaler for dynamic provisioning of spot/on-demand nodes
HPA & VPA –
- grained
- level autoscaling based on CPU/memory or custom metrics
Cluster Autoscaler (legacy, tuned for GKE & AKS before migrating to Karpenter)
Security & Policy
cert-manager – ACME automation and
- signed certificate issuance
OPA/Gatekeeper –
-
- code for image whitelisting, label enforcement, resource limits
Istio – service mesh for secure
-
- service communication (m
TLS, JWT auth, traffic shifting)
Hardened workloads via Pod
Security
Context, App
Armor/Seccomp profiles
Monitoring & Observability
Prometheus, Grafana, Loki, Alertmanager – full metrics and log stack per namespace/env
Jaeger + Open
Telemetry – distributed tracing and performance monitoring
Fluent Bit, Elasticsearch, Kibana – centralized logging pipelines
Readiness/liveness probes and SLO-based alerting
Key Projects & Achievements
Designed and built a fully Git
Ops-native deployment platform using the complete Argo stack integrated with Vault, KEDA, and custom Helm charts
Migrated 30+ legacy apps from Docker Swarm and VM-based environments to Kubernetes with minimal downtime
Implemented progressive delivery using Argo Rollouts + Istio for safe and reversible changes
Built dynamic dev/test preview environments using Dev
Space and Argo Events
Enabled secure workload identity and multitenancy across EKS and GKE clusters
Responsibilities:
- Design, build, and maintain software delivery pipelines and infrastructure that support continuous integration, delivery, and deployment.
