Yashwant Das

Senior QA Engineer · AI-Assisted Test Systems · OTT/Media · Fintech · E-commerce

12 years designing quality systems where AI-assisted reasoning works alongside
deterministic validation — not as a replacement for it.


Portfolio  LinkedIn  Medium  Hugging Face


What I work on

Area Detail
Agentic QA systems LLM-assisted reasoning with confidence scoring, deterministic guardrails, and human-in-the-loop checkpoints
Vision-based automation UI understanding from screenshots, multimodal test exploration, visual fallback strategies
Explainable test repair Failure analysis pipelines that produce auditable decision artifacts — when something breaks or gets fixed, there's a clear record of why
OTT/Media quality Playback validation, DRM compliance, cross-device certification across 8+ platforms
CI/CD quality gates Classical automation integrated with AI-assisted validation signals, without turning the pipeline into a black box

Selected work

Project Stack Description
test-playwright-protocol TypeScript, Playwright Smart Playwright Protocol (SPP) — a lightweight, protocol-driven workflow for AI-assisted Playwright automation using Markdown tasks, verification gates, and Page Object best practices.

How I think about this work

I'm skeptical of QA systems that treat model output as ground truth. My preference is architectures where AI handles the fuzzy work — pattern recognition, failure summarization, test suggestion — while deterministic checks enforce the invariants that actually matter. Every automated decision should be auditable. Claims about AI-assisted testing should be defensible in production, not just in demos.
