Acting as the sole QA Engineer, with end-to-end ownership of QA activities, test strategy, automation, and quality delivery for a fast-paced healthcare product.

• QA Ownership: Own the full QA cycle, including test planning, risk assessment, test execution, defect analysis, regression testing, and release readiness.
• API Automation: Design, develop, and maintain automated API test suites using Python, Pytest, httpx, and asynchronous testing, covering functional, negative, integration, and edge-case scenarios.
• Test Automation & Framework Development: Build and continuously improve a scalable API automation framework with reusable fixtures, test utilities, parameterization, reporting, and environment configuration.
• AI-Assisted QA Engineering: Use AI-powered development tools, Cline, and OpenAI APIs to accelerate test development, generate and improve test scenarios, analyze complex logs, investigate failures, and work more efficiently with unfamiliar code and architecture.
• Performance Testing: Design and execute load and performance tests with Locust, analyze system behavior under concurrent traffic, identify bottlenecks, and validate backend stability.
• Database Testing: Work with PostgreSQL for backend data validation, data integrity checks, SQL queries, and verification of API-to-database interactions.
• Manual Testing: Perform comprehensive functional, integration, regression, exploratory, cross-browser, and cross-platform testing of web and mobile applications.
• Defect Analysis: Investigate failures, reproduce complex issues, analyze logs and API responses, identify potential root causes, and provide detailed technical information to developers.
• CI/CD & Test Reporting: Integrate automated tests into Jenkins CI/CD pipelines, configure and maintain automated test execution, manage test environments, and generate Allure reports for test results analysis and reporting.
• Collaboration & Quality Delivery: Work closely with developers and product stakeholders to clarify requirements, identify risks early, and ensure stable releases in a healthcare environment.
• Git & Engineering Workflow: Work with Git/GitHub as part of the development and automation workflow, including code reviews, branching, and test-related changes.
