Automated SAP S/4HANA (FICO) workflows using Tricentis Tosca (model-based testing, reusable modules, E2E/regression) and enhanced stability with AI-driven features like self-healing. Migrated Cypress → Playwright, integrated CI/CD via GitLab & Docker, and validated complex data flows and DNS-based routing.

I automated document migration validation workflows using Cypress, integrating backend migration tasks and verifying successful transfers in AWS storage to ensure data integrity across high-volume migration cycles. I also enabled CI/CD execution through Jenkins, defined test scenarios using Cucumber, built reusable validation flows, and used tools like Charles Proxy while monitoring QA metrics to improve overall release quality and stability.

I designed and executed manual and automated test cases for complex business workflows, building scalable automation frameworks using Cucumber and Selenium (Java) with BDD practices to improve collaboration and release quality. I also integrated automation into CI/CD pipelines using GitLab and Docker, conducted performance testing with JMeter, and performed root cause analysis of critical defects to support timely resolution and system stability.

Owned end-to-end UI and API testing, including test strategy, manual test design, and defect management in Jira, while designing and maintaining automation frameworks using Selenium and Cucumber for continuous execution. Improved test efficiency by 70% through reusable automation scripts (Java), automated REST API validations, integrated CI pipelines with Jenkins, and collaborated with security teams to validate vulnerability remediation workflows.

I have extensive experience in testing Oracle E-Business Suite (EBS), with a strong focus on the Supply Chain Management (SCM) module, ensuring the reliability and performance of critical business processes. I designed and executed end-to-end test flows, automated key scenarios using Selenium, and continuously refined test cases to adapt to changing requirements and meet project deadlines.
