QA Engineer - Manual Testing Automation API Testing SQL Nukkad Shops Technologies (India) Pvt Ltd, Hyderabad April 2024 - August 2026

● Performed end-to-end Manual Testing - requirement analysis, test scenario and test case design, test execution, functional, integration, system, regression, smoke, sanity, exploratory and ad-hoc testing, cross-browser/cross-device validation and UAT - for web and mobile applications across multiple Agile sprints, maintaining a requirement traceability matrix for full coverage.

● Designed and maintained Automation frameworks using Playwright with Python, Pytest and Selenium WebDriver following the Page Object Model with reusable utilities and data-driven test data; built comprehensive automated and manual test suites for regression, smoke and end-to-end coverage, executed in parallel/headless mode and integrated into CI/CD pipelines via Git/GitHub.

● Conducted REST API Testing using Postman on payment, inventory and loyalty endpoints - request/response payload validation, HTTP status codes, JSON schema validation, authentication and error handling; automated API regression using Python scripts and Newman CLI.

● Performed SQL database testing and backend data validation by writing SQL queries (SELECT, JOIN, WHERE, GROUP BY) to verify data integrity, validate test data, cross-check API responses against database records and support defect root-cause analysis.

● Leveraged AI-powered testing tools including Testim and Applitools for intelligent visual testing and self-healing automation, and ChatGPT to accelerate test case generation, test data preparation and script development - significantly reducing manual effort.

● Tracked and managed defects in JIRA with detailed reproduction steps, SQL evidence, API logs, severity and priority; collaborated with developers on retesting and defect sign-off per STLC standards.

● Led QA for POS deployments at 3 airports (Goa, Hyderabad, Delhi) with on-site manual, API and SQL validation - achieved zero critical post-release defects across all go-lives while participating in Agile/Scrum ceremonies aligned to sprint delivery timelines. KEY ACHIEVEMENTS

● Reduced regression testing cycle time by combining Playwright automation, AI-powered test generation and SQL data validation - delivering faster, higher-quality releases.

● Achieved zero post-deployment critical defects across 3 airport POS rollouts through comprehensive manual, automation, API and SQL database testing.

● Delivered bug-free release cycles across multiple Agile sprints; recognised by team leads for proactively identifying critical defects before production using AI-assisted test analysis.

● Automated repetitive manual test cases using Playwright with Python and AI tools - freeing team bandwidth for exploratory and edge case testing. EDUCATION
