Work Experience

Ericsson Global, DevOps Engineer 04/2021 – 08/2024 Bengaluru, KA

Built Jenkins CI/CD pipelines from scratch automating code pull, Maven build, Docker image creation, ECR push, and SSH-based deployment to EC2, reducing deployment time by an estimated 40%.

Wrote Jenkins files independently to define end-to-end pipeline stages, eliminating manual build initiation and minimizing deployment errors across environments.

Containerized applications using Docker within Jenkins pipelines, ensuring consistent and portable runtime environments across development and production.

Managed AWS cloud infrastructure including EC2, S3, RDS, VPC, and IAM across multiple environments, maintaining high availability for production workloads.

Monitored application and infrastructure health using Prometheus and Grafana, investigating disk space and resource utilization alerts to prevent service degradation.

Configured logging, alerting, and notifications using CloudWatch and SNS, enabling proactive incident detection and faster resolution response.

Collaborated in agile release cycles to support repeatable, low-defect application deployments across multiple web application versions.

L&T Technology Services, Senior Test Engineer 02/2016 – 04/2021 Bengaluru, KA

Reduced manual regression testing effort by 70% by designing and implementing a data-driven automation framework using Robot Framework and Python.

Built a reusable automation framework that improved test script execution time and long-term maintainability across multiple project modules.

Integrated Robot Framework test execution into Jenkins pipelines, generating detailed reports and logs for defect analysis and test result tracking.

Increased test coverage by implementing automated tests for critical business workflows across Selfcare, Customer Care, and Reseller Care web applications.

Reduced production defects by identifying high-severity issues early in the testing cycle through systematic test case design for critical business modules.

Authored and maintained test documentation including test plans, test cases, defect reports, and test summary reports to support structured QA delivery.

Contributed to successful releases of multiple web application updates with minimal post-release defects through disciplined functional and regression testing.

Projects

Infrastructure Provisioning using Terraform

Managed multi-environment AWS infrastructure using Terraform with S3 remote state backend and DynamoDB locking, ensuring safe concurrent team usage.

Used environment-specific. tfvars files and Terraform workspaces to provision and isolate dev, staging, and production environments consistently.

Wrote modular Terraform configuration files to provision EC2 instances automatically, replacing manual console-based setup and enabling version-controlled infrastructure.

Integrated Terraform execution within a Jenkins pipeline to automate infrastructure provisioning on every pipeline run, enabling GitOps-style IaC workflows.

Developed reusable Terraform modules enabling repeatable environment creation and consistent scaling across multiple deployment stages.
