Summary
👤
Senior🎓
Top SchoolAlexey Kuritsyn is a Machine Learning Engineer and Ph.D. physicist based in San Jose with 8+ years building production ML systems across AdTech, bioinformatics, and scientific instrumentation. He combines top-1% Kaggle expertise and deep experience with large-scale ranking and RTB systems (Amobee/Nexxen) with a strong record of R&D leadership in optics and genomics (KLA, Pacific Biosciences), delivering measurable system and yield improvements. Comfortable from low-level signal and image processing to neural LLM fine-tuning, he regularly ships models in PyTorch/TensorFlow, Spark, and GPU-accelerated environments. Alexey has driven cross-functional teams, mentored engineers, and translated complex physical-system requirements into practical software and control solutions, holding 10+ patents and 26+ publications. Notably, his background in plasma and laser physics informs a rare ability to blend principled physical modeling with modern ML for high-stakes, instrument-level optimization. Currently contributing to Instagram Graph Ranking at Meta, he brings both academic rigor and production-first instincts to large-scale ML problems.
