Ilya Zarembsky is a QA specialist with nine years of experience ensuring stability and smooth releases for productivity and consumer-facing products, most recently at Duolingo after leading QA and release coordination at Motion. He blends hands-on frontend development experience—contributing UI improvements to the widely used Ghostery browser extension—with structured QA and release processes to ship frequent feature-driven updates. Ilya's background in game design (NYU MFA) and university-level teaching gives him a strong systems-thinking approach to user experience, test design, and cross-functional collaboration. Comfortable moving between tooling, test strategy, and hands-on bug fixes, he focuses on reducing friction for product teams while maintaining high quality. Outside work he’s a long-distance runner, ~2000 FIDE classical strategy gamer, and urban explorer—interests that reflect discipline, pattern recognition, and curiosity he brings to technical problems.
