Summary
Oleksii Piddiachyi is a Kyiv-based research scientist and one of Ukraine’s few dedicated reinforcement learning researchers, bringing 10 years of experience across data science, deep learning, and AI consulting. He has moved between industry and academia roles—from data scientist and ML engineer to lecturer and research engineer—shipping applied RL and big data solutions at companies like VARTEQ, Vodafone, and Neo Cybernetica. A trained software engineer with a background in backend development, he combines production-focused engineering with research rigor, making him effective at turning experimental models into deployable systems. He shares insights publicly as a podcaster and Medium writer, and cultivates a provocative “Data Satanist” persona on GitHub that reflects a curiosity-driven, contrarian approach to data problems. Notably, his profile blends hands-on model development with teaching and public communication, a mix that helps translate complex RL ideas for practitioners and learners alike.
