QA engineer ensuring API and UI quality with full-stack testing expertise.
IndiaWhat I'm looking for
I’m a QA Engineer with a full-stack development background, combining strong testing fundamentals with deep understanding of application internals. I focus on validating both frontend behavior and backend API contracts to keep releases stable and predictable.
I’ve performed manual functional and regression testing on scheduling features, documented defects before releases, and validated REST API endpoints using Postman (payloads, HTTP status codes, and error handling). I also tested end-to-end UI flows post-refactor across React and Angular, and verified third-party integrations like Google Calendar API and Stripe billing flows.
I work comfortably in Agile/Scrum—triaging and tracking bugs across sprints and collaborating with senior developers during code reviews. I’m actively preparing for ISTQB CTFL and learning automation with Selenium WebDriver and Cypress to expand my impact.
