Production-Grade Resilient AWS Infrastructure

• Architected a multi-AZ Auto Scaling Group inside a custom VPC using Launch Templates and Golden AMIs, eliminating single points of failure across the EC2 fleet.
• Designed CloudWatch alarm-driven scaling policies (CPU-based scale-in/out) wired to SNS notifications for real-time infrastructure health alerting.
• Enforced least-privilege access using scoped IAM roles and policies, keeping provisioning and scaling actions tightly permissioned.
• Authored a 10+ step IaC-style provisioning pipeline, version-controlled via Git — simulating production-grade operational runbooks and repeatable delivery.

Containerized Full-Stack Analytics Platform

• Containerized a Flask + MySQL stack with Docker & Docker Compose, enabling single-command deployment and full environment parity across dev/prod.
• Decoupled all sensitive configuration into .env files, enforcing secrets hygiene and aligning with enterprise compliance standards.
• Designed a multi-container network with isolated service boundaries (app, db, cache), simulating microservices-style orchestration on a single host.
• Persisted data via a named Docker volume, decoupling container lifecycle from database state to prevent data loss on rebuilds.

Production-Grade Kubernetes Orchestration on AWS EKS

• Provisioned and managed an Amazon EKS cluster, configuring aws-cli and kubectl context to control the cloud cluster directly from the terminal.
• Pushed and versioned container images to Amazon ECR, with EKS pods pulling directly from the private registry via IAM-authenticated image pulls.
• Modeled workloads as Kubernetes Deployments with defined replica counts, rolling update strategies, and resource requests/limits for predictable scheduling.
• Enabled Horizontal Pod Autoscaling (HPA) based on CPU utilization, allowing the cluster to scale replicas up/down with real demand.

DevOps Intern

• Designed and maintained end-to-end CI/CD pipelines using Jenkins, automating build, test, and deployment workflows for containerized applications on Linux — significantly reducing manual deployment overhead and accelerating release cycle.
• Architected and managed AWS infrastructure (EC2, S3, IAM) with CloudWatch monitoring, implementing access control policies and storage lifecycle management to ensure system reliability, uptime, and security compliance in a near-production environment.

DevOps Intern

• Configured a Java Maven CI pipeline in Jenkins, deployed containerized workloads on Kubernetes (Minikube) with real-time system health monitoring via Netdata — delivering a complete build-to-deploy lifecycle with full observability.
• Automated static site delivery using GitHub Actions and GitHub Pages, establishing version-controlled release workflows and reinforcing continuous delivery best practices across the development lifecycle.
