PROFESSIONAL SUMMARY
Senior Manual QA Engineer with 15+ years of experience in web applications, e-commerce platforms, API testing, and
distributed systems. Strong expertise in functional, regression, integration, and end-to-end testing of complex business-
critical products and payment flows. Specialized in Salesforce Commerce Cloud (SFCC), headless commerce, and backend
validation for high-scale retail platforms. Experienced in API testing with Postman, HTTP/HTTPS protocols, SQL-based
data validation, Chrome DevTools, and AWS-based services. Proven ability to independently own QA processes, analyze
business requirements, identify edge cases early in the SDLC, and collaborate effectively with cross-functional Agile teams.
Actively applies AI tools (ChatGPT, Claude) as part of the QA workflow — through prompt engineering for test case
design, log analysis for root-cause investigation, drafting QA documentation and defect reports, and summarizing complex
technical documentation — to speed up analysis and improve QA efficiency.
