Junior DevOps Engineer — CaptoSoft Digital Solutions Pvt Ltd July 2023 – Present Pune, Maharashtra

● Provisioned and secured AWS infrastructure — EC2, IAM, VPC, S3, Route 53, RDS, CloudWatch, Security Groups, and ELB/ALB — supporting 4–8 production and staging environments, achieving consistent least-privilege access control across all accounts.

● Designed and maintained CI/CD pipelines using Jenkins, GitLab CI/CD, and GitHub Actions integrated with SonarQube, Maven, Nexus, and Trivy, enabling multiple production deployments per week while catching code quality and security issues before release.

● Deployed and managed containerized applications on Kubernetes (Amazon EKS) by configuring Deployments, Services, Ingress, ConfigMaps, and Secrets, and packaging releases with Helm charts to standardize application delivery.

● Automated infrastructure provisioning with Terraform, standardizing environment setup across teams and cutting manual provisioning time by over 50%.

● Containerized and operated multi-service application environments with Docker and Docker Compose across development and staging, improving environment parity and onboarding speed.

● Implemented GitOps-based delivery using ArgoCD for declarative, Git-driven Kubernetes deployments, simplifying rollbacks and improving environment consistency.

● Configured monitoring and observability with Prometheus, Grafana, and AWS CloudWatch, improving system visibility and reducing mean time to detect production issues.

● Applied networking and security best practices across VPC, Subnets, Security Groups, NACLs, SSH, and IAM roles/policies to maintain secure, audit-ready cloud environments.

● Performed Linux server administration and cross-stack troubleshooting — package management, user access control, and application deployment issues — using Bash scripting to automate day-to-day operations.

● Contributed to incident response and cloud cost optimization efforts, reducing AWS resource costs while applying zero-downtime deployment strategies to minimize manual intervention. PROJECTS

Cloud-Native E-Commerce Platform on AWS EKS

● Architected a cloud-native e-commerce platform with a React frontend hosted on Amazon S3 and distributed via CloudFront CDN with Route 53 DNS routing, paired with a Dockerized Spring Boot backend deployed on Amazon EKS.

● Configured traffic routing through an Application Load Balancer (ALB) and Kubernetes Ingress Controller to internal Services and Pods, enabling reliable request distribution across the cluster.

● Integrated Amazon RDS (PostgreSQL) as the application datastore and migrated database credentials into AWS Secrets Manager, eliminating hardcoded secrets from the codebase.

● Built an end-to-end CI/CD pipeline with Jenkins and GitHub spanning Maven build, SonarQube analysis, Docker containerization, Trivy image scanning, and push to Amazon ECR, with automated Kubernetes rolling updates for zero-downtime releases.

● Configured monitoring and alerting with Amazon CloudWatch logs and metrics integrated with AWS SNS, automating email notifications on infrastructure irregularities. Node.js Application Deployment Automation Suite

● Automated the full deployment lifecycle for a Node.js application on an AWS EC2 Linux server by writing four production-style Bash scripts (deploy.sh, health-check.sh, rollback.sh, log-rotate.sh), eliminating manual deployment steps and standardizing the release process.

● Orchestrated application process management with PM2, configuring automatic restarts and crash recovery to keep the Node.js service running continuously across deployments and server reboots.

● Implemented automated health monitoring by scheduling a Bash-based health-check script via cron to run every 5 minutes, using curl-based HTTP status checks against a dedicated /health endpoint to proactively detect downtime.

● Built a Git-based rollback script that automatically reverts the application to the last stable commit and restarts the service, reducing recovery time and manual intervention after a failed deployment.

● Version-controlled the complete automation suite with Git and structured the project (app, scripts, logs) for direct integration into a CI/CD pipeline, laying the groundwork for pipeline-driven deployments. CERTIFICATIONS
