Alexander Vasilyev
Summary
👤
SeniorAlexander Vasilyev is a data scientist and machine learning engineer with a PhD in computational and applied mathematics and 14 years of experience building production ML systems and consumer-facing products. He co-founded Sleep Journey App and Ploceus.ai and currently leads machine learning at Nefta, where he designs deep learning-driven conversion, LTV and churn models and real-time distribution systems that optimize bid floors and publisher revenue. His background spans applied research, production deployment and product management—from implementing content-aware image processing and GAN experiments at Celtra to shipping growth ML models at Liftoff. Alexander combines rigorous academic research (multiple peer-reviewed papers and an open-source mathchem package) with hands-on engineering across Python, PyTorch, Spark and cloud deployments. He has a track record of turning novel algorithms into user-facing features and automated systems that self-correct in real time. Based in Slovenia, he brings an uncommon mix of mathematical depth, creative product instincts and startup grit.
