• Majorly responsible for release management, conducting comprehensive regression, user acceptance (UAT), and smoke testing across web, Android, and iOS builds. • Automated existing manual test cases into automated end-to-end tests using Playwright (TypeScript) for each feature, covering both happy paths and critical negative use cases to validate system behavior under various conditions. • Maintained API tests using Playwright framework ensuring backend reliability and integration quality.

• Validated automotive infotainment firmware on hardware benches and simulators, identifying critical defects before OEM milestone sign-off. • Partnered with developers and product owners to clarify ambiguous requirements, demonstrating strong stakeholder communication and reducing late-stage rework. • Executed system and integration tests across hardware and software interfaces in compliance with OEM specifications.

• Extended an existing Playwright automation suite for a regulated crypto-asset platform by converting manual regression scenarios for updated features into automated scripts, streamlining test cycles across bi-weekly releases. • Built Postman REST API collections covering major endpoints, early detection of integration failures and reducing post-release incidents.

• Ensured quality standards for Android and iOS mobile applications serving a user base of over 100k for a student app platform. • Defining test strategy, built regression suites, and cultivated a quality-first culture across 3 years of rapid growth. • Covered full testing spectrum: manual, regression, performance, and usability across Android and iOS apps. • Clear defect reporting with root cause analysis and reproduction steps, improving developer bug fixing capabilities.
