About

Professional summary

I am a Senior Data Scientist and Machine Learning Engineer with over seven years of experience developing production machine learning systems across ad tech, retail, industrial optimization, and telecommunications.

I specialize in ranking and recommendation systems, classification and regression, uplift modeling, predictive optimization, and experimentation. My work has delivered measurable business outcomes, including CPM uplift for advertising traffic, improved out-of-stock prediction, and increased industrial throughput and recovery.

I build end-to-end ML solutions, from data preparation and feature engineering to offline evaluation, deployment, monitoring, and iterative improvement. I have experience working with large-scale datasets, including hundreds of millions of sensor records and millions of daily traffic slices.

My technical background includes Python, SQL, gradient boosting, deep learning, factorization machines, and reinforcement-learning-related approaches such as multi-armed bandits. I use PyTorch, scikit-learn, Vowpal Wabbit, and distributed data-processing tools to develop reliable models.

I am experienced in MLOps and production observability, including Airflow orchestration, Docker, MLflow, CI/CD, data-quality validation, and monitoring with Grafana and VictoriaMetrics. I focus on creating measurable, maintainable ML systems that support real-world decision-making.

I hold a Specialist Degree in Mathematics, equivalent to a Master's degree, from Lomonosov Moscow State University. My mathematical foundation supports my work in machine learning, probability, optimization, and data-driven product development.

Career history

Senior Data Scientist AdTech Holding

Designed, developed, and deployed ranking models for ad recommendation using Linear Models, FFM, and DeepFM. The models predicted CTR and conversion rate from user, publisher, advertiser, and campaign context, delivering approximately 1–1.5% CPM uplift across production traffic.

Developed CPA bid optimization models with Vowpal Wabbit and FFM, integrating predicted conversion probabilities into automated bidding and fallback pricing logic. Built a Traffic Quality platform that scores 10–15 million traffic slices daily, as well as off-policy evaluation, Airflow-based monitoring, VictoriaMetrics, and Grafana observability pipelines for model and data-quality monitoring.

Senior Data Scientist Grid Dynamics

Built and delivered an MVP out-of-stock prediction system for a grocery delivery marketplace spanning approximately 1,000 stores and 10 million store-product pairs with hourly scoring. The solution improved the primary metric by approximately three percentage points over a rule-based baseline.

Developed end-to-end LightGBM and Airflow pipelines covering feature engineering, cold-start handling, probability calibration, time-based validation, and configurable product-blocking thresholds. Also developed a Similar Items reranking system using visual similarity and customer purchasing behavior, including target design, NDCG-based offline evaluation, and production inference pipelines.

Senior Data Scientist KAZ Minerals

Developed a predict-then-optimize recommendation system for industrial process control using XGBoost, CatBoost, and Differential Evolution. The system increased throughput by approximately 3% and recovery by approximately 1%.

Built end-to-end ML pipelines for feature engineering, training, inference, optimization, deployment, and monitoring using more than 500 million historical sensor measurements. Implemented optimization objectives, operational constraints, and penalty terms to produce actionable process recommendations.

Data Scientist VEON Kazakhstan

Developed a household detection model using telecommunications behavioral data by generating subscriber-pair candidates, scoring relationships with LightGBM, applying probability thresholds, and merging relationships into household groups with graph connected components.

Built predictive models and data marts for customer value management, including churn prediction, multi-SIM detection, and demographic inference for age, gender, and income. Developed geospatial analytics products for mobile advertising, including home and work location detection, mobility matrices, geo-activity datasets, and interest profiles.
