RAHUL GHOSAL

I’m a results-driven QA Automation Engineer (SDET) with 4+ years of experience designing and implementing end-to-end test automation frameworks using Playwright (TypeScript/JavaScript) and Cypress across web and mobile (Android & iOS) platforms. I architected the complete QA function across 4 simultaneous international client products, covering test plan authoring, test case design, defect management, API testing, and AI/LLM quality assurance.

I delivered an 80% reduction in manual regression effort by integrating automation suites into CI/CD via GitHub Actions, while consistently maintaining zero critical-severity production defect escapes across major releases. I specialize in AI/LLM testing—hallucination detection, prompt injection, RAG pipeline validation, bias testing, and latency/performance analysis—using DeepEval and RAGAs, and I enjoy owning the full QA lifecycle end-to-end.
