About Abhinav Kumar Dubey

I am a results-driven QA Engineering Leader and Principal SDET with 12+ years of experience architecting scalable quality ecosystems across Healthcare, Fintech, and Telecom. Specialize in future-proofing software by blending high-velocity deterministic engineering(UI, API, Mobile, Performance) with the frontier of non-deterministic AI system validation (RAG, Agentic AI, STT systems).I don’t just test; I transform. From leading organisational Quality Engineering shifts to building modular frameworks from scratch, my mission is to turn QA from a bottleneck into a strategic accelerator.The Expertise I Bring:1. Deterministic Testing : 12+ years of hands-on mastery in UI, API, and Mobile automation using Selenium, Playwright, Appium, and Rest Assured.Built metrics-driven performance engineering practice using JMeter,ensuring SLA compliance under peak production load.2.Non-Deterministic AI Evaluation: Engineered a metrics-driven testing framework replacing \"vibe checks\" with automated evaluation. Improved RAG Reliability through rigorous tracking of Context Precision, Faithfulness, and Answer Relevancy. Optimized Agentic AI workflows by reducing redundant tool calls using Step Efficiency scores and achieving a 95% Task Success Rate on complex multi-step benchmarks.3.AI Test Pyramid & Shift-Left DNA: I implement a structured AI Test Pyramid (Unit Tool-calling → Component → Integration → E2E) to ensure AI reliability. By leveraging LLM-as-a-Judge and Golden Dataset generation, I ensure precision in healthcare-specific and financial use cases.4. Operational Excellence:Orchestrated Blue-Green deployments with AI-backed risk signals, maintaining a 99.9% success rate with zero production downtime.5. Strategic Leadership:Proven track record in mentoring high-performing SDET teams, reducing MTTR by 25%, and driving technical maturity through code reviews and engineering discipline.Technical Power Stack:1. AI/ML QA: RAGAS, Promptfoo, DeepEval, OpenAI Whisper, Sarvam, LLM-as-a-Judge, Hallucination Detection.2. Automation & Performance: Playwright, Selenium,Rest Assured, Appium, JMeter, BrowserStack,K6, Karate DSL.3. CI/CD: Jenkins, Git (GitHub, Bitbucket), GitHub Actions, Maven, Docker,Kubernetes, SonarQube etc4. Cloud & DevOps: AWS (EC2, S3, Lambda), Docker, Kubernetes, Jenkins, Git.5. Observability:Arize Phoenix, Langfuse, CloudWatch,Confident AI,Grafana,New Relic etcI am passionate about building a culture of quality, mentoring the next generation of engineers, and leveraging Generative AI to redefine the limits of software excellence.
