Zero-Downtime Kubernetes Upgrades

Zero downtime

Planned and executed sequential Kubernetes upgrades across five production EKS clusters, resolving version drift while keeping high-traffic workloads available throughout.

Karpenter Capacity Optimization

Reliable provisioning

Retuned NodePool and EC2NodeClass capacity, disruption, and consolidation policies alongside scheduling constraints and PodDisruptionBudgets to stabilize provisioning and scale-in.

Karpenter on EKS Fargate

No controller-only nodes

Moved Karpenter controllers from dedicated managed node groups to EKS Fargate, removing their bootstrap dependency and eliminating dedicated always-on capacity maintained solely for the controllers.

Policy as Code Before Sync

No admission webhook

Contributed to Argo Guard, validating rendered manifests with Conftest and OPA before Argo CD sync. This removed an admission webhook from the API request path, reducing operational overhead and webhook-related deployment risk.

Multi-Cluster Segregation

Stronger fault isolation

Led workload segregation by business domain to strengthen fault isolation and operational independence, using Argo CD's App of Apps pattern for consistent multi-cluster delivery.

Bitbucket to GitHub Migration

4,000+ repos

Automated the migration of 4,000+ repositories from Bitbucket to GitHub with Go and Bash, including repository configuration, CI/CD onboarding, and Argo CD manifest-repository synchronization.

Internal Developer Platform

Self-service onboarding

Built a Backstage-based internal developer platform with self-service templates for service scaffolding, ECR and Vault provisioning, database connectivity, and Argo CD/CI onboarding.

GitOps & Infrastructure

PR-based controls

Migrated Terraform workflows to Atlantis for PR-based approvals, resolving state-lock concurrency issues while maintaining Terraform modules and reviewing AWS CDK changes.

Security & Cost Optimization

Actionable cost data

Implemented OpenCost and Kubeadapt with SSO plus Athena cost pipelines for Spot/On-Demand analysis, creating the visibility needed for node-pool optimization.

CI/CD Pipeline Engineering

Reusable delivery

Built and improved reusable GitLab CI/CD pipelines for microservices, adding quality gates, caching, artifacts, and automated documentation to make delivery more consistent.

Linux System Administration

Hardened systems

Administered production and development Linux systems: kernel updates, performance tuning, security hardening.

Monitoring & Observability

Faster diagnosis

Implemented Prometheus, Grafana, and ELK observability with custom dashboards and Kubernetes log lifecycle policies, improving visibility and preventing disk exhaustion.

RAG-Based DevOps Agent

Reusable knowledge

Built a retrieval-augmented knowledge assistant with vector embeddings and semantic search to make previously solved operational issues discoverable and reusable.

Argo Guard

Pre-deployment Policy Guardrails for Argo CD

Source

An open-source Argo CD Config Management Plugin that validates rendered Kustomize manifests before they reach a cluster. It keeps policy enforcement in the GitOps render path, protecting running workloads and the Kubernetes control plane from admission-webhook failures.

  • Pre-deployment validation inside argocd-repo-server
  • Layered policies scoped by trusted application context
  • Fail-closed behavior with readable Argo CD reports
  • No policy webhook in the cluster admission path
