• I've worked in Yandex Ads Antifraud group and developed machine learning models for fraud detection, which protect the ads of more than 400K advertisers.
• Developed a new deep learning model. This model uses pre-trained LLM as a base.
• Conducted research that led to a reevaluation of the overall fraud-banning strategy, resulting in a 0.5% increase in unique bans. Additionally, optimized 2% of unique bans, preserving 20% of funds that were previously.
• Developed an automatically updating dashboard for tracking advertising event metrics across different slices. Designed a clear and minimalistic metric system tailored to a human evaluation of ban rule effectiveness.

• I worked at the Redmadrobot Data Lab (RDL) unit and developed AI solutions for manufacturing. In all projects, I used SOTA approaches and deep learning (DL) architectures.
• Developed an iterative algorithm for determining the number of grinding bodies in mills at a mineral processing plant. Best MAE: 90% (Mean human analysis MAE was 80%).
• Solved multi-class instance segmentation computer vision (CV) challenges for the mineral processing plant (detection of dump trucks, dump cars, their components, ore hills, and oversized pieces of ore in ore hills).

• I've worked in the AI-based business solutions laboratory. Some projects:
• R&D for the modular business process optimization platform "Positron". This is an AI-unified decision library (CV, NLP, predictive analytics).
• R&D for the modular platform of unified decisions for the optimization of manufacturing processes called "Terrific.AI". It includes flaw detection on conveyor belts (CV), automatic scheduling for equipment, and quality.

• I worked in R&D on various AI-based business solutions for B2B. It produces AI solutions for customers from the USA, Europe, and Russia. Clients include Gazprom, the biggest banks, retail and telecommunication.
• Named-entity recognition (NER) tasks in different fields (education, medicine, jurisprudence) for European companies.
• R&D for a product Electra.AI. It is a generative AI platform for fast-creating chatbot assistants for call center operators. This platform allows for up to a 60% reduction in costs associated with the manual work of.
