Objective: Implemented comprehensive cross-browser testing strategy using BrowserStack to ensure optimal product performance across multiple browsers and devices, reducing QA cycle time and improving release confidence.

Role: Led quality assurance and testing infrastructure as Senior QA Engineer. Owned the entire BrowserStack integration, from vendor evaluation to team onboarding and best practices documentation.

Solution: Configured automated test suites across 100+ browser-device combinations. Integrated BrowserStack API with CI/CD pipeline (Jenkins) for real-time parallel testing. Established testing protocols reducing manual testing by 65%.

Tech Stack: BrowserStack, Selenium, Jenkins, JavaScript, REST APIs.

Business Impact:

- Reduced bug escape rate by 48% (QA-reported vs production defects)

- Test execution time cut from 4 hours to 28 minutes (parallel execution)

- Achieved 99.2% cross-browser compatibility before production release

- Improved developer productivity with automated regression testing

Timeline: Fully operational in 8 weeks from POC to enterprise deployment.

Scope: Solo project; trained 12 QA team members on automation framework and best practices.
