Software testing skills and QA tools.

Manual and functional testing

I use a structured approach to testing: understand the requirement, map business rules, select representative inputs, execute carefully, and record reproducible observations.

• Functional and exploratory testing
• Positive, negative, boundary, and state-transition scenarios
• API validation and persisted data checks
• Defect reproduction and regression planning

QA tools and technical checks

• Postman for API request checks, response validation, and negative cases
• Selenium, Cypress, and Playwright basics for browser automation practice
• SQL, PostgreSQL, and MongoDB checks for data correctness
• Chrome DevTools for network, console, storage, and UI investigation
• Git, Docker, and Linux familiarity for test environments and collaboration

How I support a QA team

I can investigate issues across the browser, API response, and stored data, then report the smallest reliable reproduction path. My goal is to make each defect clear enough for fast triage and each retest clear enough for release confidence.
