Yaroslav Dubrov

I’m a Senior QA Engineer with 8+ years delivering quality across web, mobile, API, and AI-powered products in AI, HRTech, Travel/Hospitality, and EdTech. I focus on turning quality issues into measurable product improvements—earlier defect detection, fewer user-flow drop-offs, shorter regression cycles, and more predictable, reliable releases.

In my current role, I ensure an AI chatbot platform delivers stable conversational and backend functionality by owning conversational flows, admin tools, backend workflows, Kafka-based processing, and RAG-related features. I’ve automated 50% of the recurring regression scope, built risk-based regression checklists and test plans, and developed a dialogue golden suite with evaluator prompt tuning and automated dialogue quality checks.

Previously, I led end-to-end QA and data-driven investigations for learning platforms, travel/hospitality products, and a voice-AI service, cutting main-flow drop-offs by ~20% and reducing mobile regression time from 8 to 6 hours. I design prompt-testing scenarios, validate STT/TTS integrations, and use SQL, analytics event validation, and replay-based debugging to find root causes—supported by automation with Python/pytest, Cypress, Detox, and Postman.
