🏗️ Infrastructure as Code
📊 Monitoring & Observability
🔐 Security & Policy
💻 Scripting & Development
🔹 Cloud-Native Microservices Platform on AWS EKS
Stack: AWS EKS Docker Kubernetes Helm Terraform Prometheus Grafana
- Designed and deployed a production-grade microservices architecture on Amazon EKS
- Implemented HPA and Cluster Autoscaler for dynamic scaling
- Configured rolling deployments & canary releases for zero-downtime updates
- Built full observability stack with Prometheus metrics and Grafana dashboards
- Used Helm charts for templated, reusable Kubernetes deployments
🎯 Impact: Deployment downtime → near-zero · Scalability improved 5x under peak load
🔹 End-to-End CI/CD Automation Pipeline
Stack: Jenkins GitHub Actions ArgoCD Docker Kubernetes SonarQube
- Built fully automated pipelines: Build → Test → Security Scan → Container Build → Deploy
- Integrated ArgoCD for GitOps-based continuous delivery to Kubernetes clusters
- Added SonarQube static code analysis and container vulnerability scanning
- Enabled multi-environment promotion (dev → staging → prod) with approval gates
🎯 Impact: Release cycle: hours → under 10 minutes · Deployment confidence increased significantly
🔹 Reusable Terraform Infrastructure Modules
Stack: Terraform AWS EKS VPC IAM RDS S3 GitHub Actions
- Authored modular Terraform modules for EKS clusters, VPC networking, and IAM
- Implemented remote state management with S3 backend and DynamoDB state locking
- Enabled consistent environment provisioning across dev, staging, and production
- Automated Terraform
planandapplyvia GitHub Actions CI workflows
🎯 Impact: Infrastructure provisioning: days → under 30 minutes · Zero configuration drift
🔹 Observability & Monitoring Stack
Stack: Prometheus Grafana AWS CloudWatch ELK Stack Alertmanager
- Deployed Prometheus + Grafana for real-time Kubernetes and application metrics
- Built custom dashboards tracking CPU, memory, pod health, request latency, error rates
- Integrated Alertmanager with Slack for real-time incident notifications
- Centralized logs with ELK Stack for searchable, long-term retention
🎯 Impact: Significant reduction in mean time to detect (MTTD) incidents
🔹 Multi-Tenant EKS Platform with Policy Enforcement 🚧
Stack: AWS EKS OPA Gatekeeper Kyverno RBAC Namespace Isolation
- Designing a multi-tenant Kubernetes platform with strict namespace isolation
- Implementing admission controllers for mandatory labels, resource limits, image policies
- Building a self-service onboarding flow for tenant teams with guardrails
🎯 Target: Secure multi-team workload isolation on shared Kubernetes clusters
🔹 Cloud Cost Optimization Engine 🚧
Stack: AWS Cost Explorer API Python Lambda Terraform CloudWatch
- Building automated detection of idle/underutilized AWS resources
- Generating rightsizing recommendations for EC2, RDS, and EKS node groups
- Automating weekly cost reporting dashboards
🎯 Target: 30%+ infrastructure cost reduction
