Senior Machine Learning & Data Engineer with 9+ years of experience in Machine Learning, Data Science, AI, and Data Engineering. Former Yandex Engineer and Head of R&D at a digital pathology startup.

I build production Machine Learning and AI systems in Python — from computer vision and NLP to predictive modeling, document AI, and large-scale data products. My background combines hands-on ML engineering, data science, and the data infrastructure needed to run these systems reliably in production.
