About Sabyasachi Ghosh

I am a Senior SDET with 11+ years of experience in building scalable test automation frameworks across microservices, Kubernetes, and cloud environments.I am currently transitioning into a GenAI Engineering role, where I design and test LLM-powered systems including RAG pipelines, AI agents, and automated evaluation workflows.My focus areas include:• LLM testing and prompt evaluation• AI agent workflows using n8n and LangChain• RAG systems with vector databases• Python-based automation for AI pipelines• Playwright-driven end-to-end validation of AI applicationsI bring a unique advantage: I don’t just build AI systems — I make them reliable, testable, and production-ready.Currently building:• SDET AI Agent that generates test cases from Jira + GitHub• LLM evaluation framework for API responses• Automated RAG testing pipelinesOpen to: GenAI Engineer • LLM QA • AI Automation • Applied AI roles (EU/Remote)
