• Created several versions of a recommendation system from scratch, alone launch it into production, set up an airflow and monitoring, and assessed its effectiveness. Result: increased AOV and ARPU. • Development of a chatbot based on LLM (models: llama2, mistral, falcon; model sizes: 7B, 13B, 70B), finetuning (LoRA/QLoRA). Development of an alternative RAG model using a vector database. Prompt engineering. • Introducing a culture of scientific approach to A/B tests based on statistical hypotheses.

• Data analysis in the B2C sector, data quality assessment, preparation of technical specifications for creating storefronts, DataFlow diagrams, GAP data analysis, coordination of requirements with the customer and product owner. • Creation of dashboards with Superset, creation of data marts, ad-hoc queries, cohort data analysis. ETL data from Hadoop using PySpark.

• Analytical projects to provide research and reports using python + Superset. For one project, based on the data obtained, a model for customer churn as part of a customer loyalty program has been created from scratch. Reduced churn rate as result. • Self-taught in Data Science and Machine Learning, studied Data Engineering tools.

• Management of the company's analytical departments in the field of infrastructure projects in Eastern Europe. Reducing resource consumption at facilities, reducing implementation time and cost. • Developing analytical reports for executive officers. • Introduction of advanced achievements in the field of geopolymers, analytical studies, management and planning of new projects. • Managing of international team from a few countries with different time zones.

• Teaching technical disciplines (building materials, math, statistics, linear algebra) at the university, research in the field of geopolymer materials. Worked on a Ph.D. thesis “Clinker-free geopolymer building materials”.

• Analytical support for project implementation regarding schedules, supply chains and construction method statements. Daily/weekly dashboards for management stuff. • Managing the team of engineers on the construction sites.

Thesis “Clinker-free geopolymer building materials”.
