What I'm looking for

I'm looking for a QA or automation testing role where I can build reliable UI and API test coverage, investigate defects, contribute to CI/CD workflows, and continue growing through hands-on collaboration with development teams.

I've built end-to-end QA automation frameworks for ShopSphere and Blogzz, covering critical user journeys across MERN applications.

For ShopSphere, I created 39 automated UI test cases with Playwright and JavaScript, integrated Jenkins CI/CD, and validated REST APIs with Postman and Newman. I identified defects in wishlist synchronization, coupon calculation, registration validation, and password recovery.

Through internships at Nissan Digital India and Zer01 Company, I've performed vulnerability assessments, OSINT analysis, API testing, regression testing, defect reporting, and validation of authentication and CRUD workflows.
