At Kaspi, I design and deploy recommendation and ranking models for Kaspi Shop across app and web, personalizing experiences for millions of users. My CatBoostRanking and Transformer-based models have delivered up to a 12% uplift in CTR and conversion.
I've run dozens of A/B tests, built ML pipelines with MLflow, Airflow, and Kafka, and improved CrossSell recommendations through iterative experimentation. Previously, I fine-tuned a 7B-parameter LLM for eOtinish at National Information Technologies JSC, improving internal NLP quality by 35%.
