About

Professional summary

I am a results-driven Quality Assurance Tester with over six years of experience ensuring software quality across web and mobile platforms. I specialize in building effective test strategies, executing comprehensive test plans, and improving product reliability in Agile/Scrum environments.

I have led quality assurance efforts for high-impact fintech and healthcare products, including savings, investment, brokerage, and health informatics platforms. My work has contributed to significant improvements in product quality, user satisfaction, and release readiness.

I am experienced in functional, integration, regression, API, performance, and end-to-end testing. I develop detailed test cases, maintain requirement traceability, validate application behavior, and provide actionable defect reports to support timely resolution.

I use automation and QA tools such as Selenium, Cypress, Playwright, Appium, Postman, JMeter, and SQL to strengthen testing coverage and improve efficiency. I also work with test management, reporting, CI/CD, and version-control platforms to support quality throughout the delivery lifecycle.

I collaborate closely with product, engineering, and business stakeholders to define quality metrics and align QA activities with organizational goals. I am committed to delivering reliable, user-focused software and continuously improving testing processes.
