DevOps & Cloud Projects

Production Systems Built & Automated

Real-world deployments covering end-to-end GitOps pipelines, container orchestration, IaC provisioning, and resilient cloud architectures.

GitOps-Driven Java Microservices CI/CD Pipeline on Kubernetes

Designed an automated end-to-end GitOps delivery pipeline orchestrating builds from code commit to zero-downtime Kubernetes deployments.
Automated Maven compilation, unit testing, and integrated SonarQube Quality Gates within a Declarative Jenkins Pipeline to halt builds on security/quality breaches.
Built optimized multi-stage Docker images running as non-root users, versioned by Git SHA/build numbers, and pushed to a secure registry.
Packaged application deployments using custom Helm charts and configured Argo CD for automated syncing with rolling update strategies and instant rollbacks.

Production Three-Tier Microservices Deployment on Amazon EKS

Architected a secure three-tier microservices application (React frontend, Node.js backend, database) running on an Amazon EKS cluster.
Enforced container security by integrating Trivy vulnerability scanning into the pipeline, blocking images with High/Critical CVEs prior to registry push.
Deployed databases via Kubernetes StatefulSets with persistent storage, non-root execution contexts, and secret segregation.
Configured pod liveness/readiness probes, resource limits, AWS ALB routing, and established cluster monitoring/alerting via Prometheus and Grafana.

Automated AWS Cloud Infrastructure Delivery via Terraform & GitHub Actions

Authored reusable, modular Terraform configurations provisioning highly available VPCs, public subnets, Internet Gateways, Route Tables, and Security Groups.
Configured remote state management using Amazon S3 with server-side encryption and DynamoDB-backed state locking to prevent deployment conflicts.
Automated CI/CD workflows via GitHub Actions with fmt, validate, artifact-stored plan, and environment-gated manual approvals before apply.
Bootstrapped EC2 web servers using Terraform User Data scripts, provisioning an Nginx server on an Elastic IP with IAM least-privilege roles.

Secure & Scalable 3-Tier Web Architecture on AWS

Architected a highly available AWS network spanning 2 Availability Zones, isolating traffic across 6 subnets with custom Route Tables and NAT Gateways.
Deployed an internet-facing Application Load Balancer routing web traffic to Nginx reverse proxies, forwarding API requests to an internal ALB fronting Flask services.
Configured Amazon RDS MySQL in private subnets with strict security group ingress rules restricted solely to backend application instances.
Configured Auto Scaling Groups and target health checks, ensuring high fault tolerance, automatic recovery, and zero single points of failure.
