Asad U.

Senior QA Engineer | AI/LLM Testing | Complex SaaS & APIs

A senior independent QA expert specializing in AI-powered applications, LLM-based products, and end-to-end testing for regulated, high-trust SaaS platforms. I help businesses validate AI-driven solutions across healthcare, telehealth, fintech, and clinical data products, where accuracy, reliability, data integrity, and trust are non-negotiable. From LLMs and AI agents to RAG pipelines and intelligent workflows, I focus on testing beyond traditional functionality—covering hallucinations, response accuracy, prompt robustness, edge cases, data privacy, API integrations, and end-to-end reliability. Because when AI gets it wrong, the impact goes beyond a bug. It can mean flawed decisions, compliance risks, failed audits, and lost revenue.
