Own QA validation for complex analytics workflows, covering end-to-end functional and regression testing across platform releases. Define and execute test strategies for platform releases, coordinating with engineering and product teams to ensure release readiness. Perform functional, integration, and API testing (REST) using Postman and SoapUI to validate data integrity across analytics services. Use SQL (via DBeaver) to validate data transformations, joins, and aggregations across datasets with millions of records, catching data integrity issues before release. Manage test cases and defect tracking in Jira and Xray, strengthening regression coverage and release stability through enhanced QA planning and test documentation. Mentor a team of 8 QA engineers on testing approach, API testing practices, and data validation techniques. Monitor production workflows using Datadog in AWS and Azure environments to investigate and reproduce issues before they escalate. Leverage AI tools (Claude, ChatGPT) to accelerate QA analysis, test scenario generation, and test documentation.
