Abhinav Mishra

DevOps/Cloud Engineer with about 1 year of hands-on experience spanning CI/CD pipeline automation (Jenkins, GitHub Actions), AWS infrastructure provisioning with Terraform (Infrastructure as Code), Docker containerization, and production observability and incident management using Splunk. Designed a personal event-driven AWS project (Step Functions, ECS Fargate, EventBridge) with automated CI/CD deployment via GitHub Actions using OIDC authentication. Comfortable with Linux administration, shell scripting, Git workflows, and root cause analysis (RCA) for production issues.

DevOps Engineer at Cognizant Technology Solutions (2026-01 – Present)

• Provisioned and managed scalable AWS infrastructure (EC2, S3, VPC) using Terraform, applying Infrastructure as Code (IaC) practices for consistent, version-controlled environments while reducing environment setup time by 30%.
• Containerized application components using Docker for consistent, container-based deployments, standardizing environments and improving developer onboarding efficiency.
• Orchestrated the deployment of containerized microservices to Amazon EKS clusters using Kubernetes manifests, improving application scalability and ensuring consistent environments across development and staging.
• Used Linux command-line administration and shell scripting daily to support build, deployment, and troubleshooting tasks across development and staging environments.
• Manage the full incident lifecycle — alert ingestion, noise reduction, creation, acknowledgment, escalation, and resolution — using Splunk On-Call (VictorOps) as part of an enterprise observability practice.
• Apply observability best practices across metrics, logs, and traces, working with Splunk Observability Cloud (SignalFx) integrated across multiple monitoring platforms.
• Conduct post-incident reviews and Root Cause Analysis (RCA), documenting technical findings and preventive actions to reduce recurrence.
• Test, debug, and validate REST API integrations and webhook payloads using Postman, reproducing and troubleshooting issues in lab/test environments.
• Track and manage bugs and enhancements through JIRA in collaboration with engineering teams for resolution.
• Author and maintain knowledge base documentation and a centralized repository of reusable troubleshooting solutions.

Associate Automation Developer at FireFlink (2025-07 – 2025-12)

• Built web, mobile, and API test automation using Selenium WebDriver, Appium, and Java, and used the FireFlink scriptless automation platform to design reusable test flows.
• Integrated automated regression suites into Jenkins CI/CD pipelines, automating test execution on every pull request and reducing manual QA feedback loops.
• Implemented dynamic locators and synchronization mechanisms to improve automated test reliability and reduce flaky failures.
• Documented test execution results using Extent Reports to support defect tracking and resolution.
• Collaborated with cross-functional teams during Agile ceremonies (sprint planning, stand-ups, retrospectives).
• Gained exposure to Salesforce automation and business workflow validation across modules.
