Docker & Kubernetes Integration GitHub & CI/CD Practices Automation Engineering

• Architect, design and maintain robust automation frameworks using Java, Selenium WebDriver, Junit/Maven and Page Object Model (POM).
• Build scalable and reusable automation libraries and utilities to support UI, API, and backend test coverage.
• Implement Cucumber BDD automation and integrate feature files with step definitions for business-readable scenarios.
• Develop and optimise API automation (REST/JSON/XML) using Java-based frameworks, Postman, and Swagger, ensuring reliable end-to-end service validation.
• Drive shift-left automation, ensuring early integration of test scripts into the development lifecycle.
• Perform root-cause analysis, debug complex issues and enhance automation stability through improved logging, error-handling and parallel execution and investigating Grafana loki logs and dashboards.
• Increase automation maturity by implementing continuous testing, test hooks, parallel execution and reporting dashboards.
• Build and manage Docker images for automation test environments, ensuring consistent, reproducible test execution across all stages (Dev, QA, Pre-Prod).
• Deploy and run automation frameworks in containerised environments, enabling lightweight, scalable and isolated test execution.
• Use Kubernetes to orchestrate distributed test executions, enabling dynamic scaling of test pods, parallel execution and auto-healing of failing test nodes.
• Refine Kubernetes resources (Pods, Deployments, Services, ConfigMaps, Secrets) to support automated test / performance test infrastructure.
• Manage source code versioning using Git/GitHub, including branching strategies, pull requests, code reviews and repository governance.
• Implement GitHub Actions (or equivalent CI tools) to trigger automated test runs, report generation and deployment validation.
• Involved in shift-left testing and constantly collaborated with development teams to ensure effective merging, conflict resolution and adherence to version control best practices.
• Maintain clean and modular code repositories, ensuring easy maintainability, readability and long-term scalability.

Automation Engineering Docker & Kubernetes Integration GitHub & CI/CD Practices Performance Testing & Monitoring (Supporting Responsibilities) DevOps & Deployment Automation

• Worked for LBG (Lloyds Banking Group) Client as SDET / QA Automation Tester, Performance tester and Code deployment engineer.
• Skilled in performance engineering using LoadRunner, Dynatrace and TeamQuest for end-to-end performance analysis and reporting. Proficient in CI/CD tools such as Jenkins, GitHub, Maven, and experienced in cross-browser, API, accessibility and security testing. Hands-on in coordinating defect triage and managing application code deployments using UrbanCode Deploy.
• Architected and maintained Java-based automation frameworks (Selenium, TestNG/Maven, POM, Cucumber BDD) with reusable libraries supporting UI/API/backend testing, and developed robust REST API automation using Java, Postman, and Swagger while driving shift-left testing across the SDLC.
• Build and manage Docker images for automation test environments, ensuring consistent, reproducible test execution across all stages (Dev, QA, Pre-Prod).
• Use Kubernetes to orchestrate distributed test executions, enabling dynamic scaling of test pods, parallel execution and auto-healing of failing test nodes.
• Manage source code versioning using Git/GitHub, including branching strategies, pull requests, code reviews and repository governance.
• Execute performance testing using LoadRunner, including scripting, load modelling and result analysis.
• Monitor system health and performance trends using Dynatrace, TeamQuest and server-level diagnostics.
• Automate code deployments using UrbanCode Deploy, enabling consistent, reliable and auditable application releases.
• Validate post-deployment functionality through automated smoke tests and environment checks.

• Worked across Retail, Finance, and Trading domains, gathering business requirements and understanding SLAs from business analysts and developers.
• Analysed functional and non-functional requirements and identified scenarios suitable for automation and performance testing.
• Automated regression test cases using Selenium and UFT, including creating and enhancing data-driven and descriptive programming scripts for desktop applications.
• Developed LoadRunner (VuGen) performance test scripts with checkpoints, rendezvous points, parameterization, correlation, and error handling.
• Performed performance analysis using LoadRunner Analysis to identify bottlenecks and system issues.
• Reported and tracked defects using HPQC.
• Led and coordinated an offshore team of five members handling automation and performance testing activities.
• Created Excel macro tools for efficient test data preparation and management.
