Lead QA initiatives for enterprise SaaS and embedded analytics platforms, defining testing strategies for complex features, integrations, and data-driven workflows. Design and execute functional, regression, integration, exploratory, API, backend, database, and end-to-end testing, validating dashboards, reporting, filters, personalization, permissions, exports, and multi-tenant functionality. Perform REST API and HTTP testing using Postman and validate backend data integrity and application behavior using SQL queries. Test AI-powered agents and Model Context Protocol (MCP) integrations, validating tool calling, prompts, context handling, API interactions, and end-to-end AI workflows. Perform manual evaluation of AI-generated outputs against defined criteria and expected results, identifying unexpected behavior and functional issues. Develop and maintain UI and E2E automated tests using Playwright and JavaScript, including assertions, test execution, troubleshooting, and test script maintenance. Apply risk-based and gray-box testing approaches by combining functional validation with knowledge of APIs, backend services, databases, and system behavior. Review acceptance criteria, coordinate QA activities across approximately 8 product releases annually, assign testing activities, review peer test cases, and mentor QA engineers. Collaborate with Product Owners, Developers, Engineering Managers, and stakeholders throughout the SDLC to improve test coverage, defect prevention, and release quality.
