About

I'm a Business Analytics Master's student in New York, focused on applying data, machine learning, and technology to business decision-making. I work as a teaching and research assistant in business analytics and information technology, helping students build quantitative and programming skills and supporting faculty research with data-driven decisions.

My path has been global: from studying analytics and industrial management in South Korea to earning an engineering and business degree at a leading technical university in Russia, and now continuing my journey in the U.S. This mix of experiences helps me approach problems from different perspectives and adapt across industries and cultures.

I work with Python, R, SQL, and Excel on projects in data analysis, risk assessment, and machine learning. Recently, I've been researching ML applications in cybersecurity, analyzing cryptocurrency return distributions, and studying yield curve dynamics.

Experience

Graduate & Teaching Assistant in Accounting & Information Systems

September 2024 - Present
St. John's University, New York, NY

As a graduate assistant, I support faculty-led financial research through advanced data analysis and statistical modeling while teaching undergraduate students fundamental statistical concepts and Excel applications. My work spans cryptocurrency market analysis, yield curve forecasting, and AI-enhanced analytics.

Key Contributions:

  • Analyzed cryptocurrency and financial market dynamics using Python (Pandas, NumPy, Matplotlib, Seaborn), assessing return distributions and volatility patterns through statistical analysis and visualization to support faculty research on market behavior
  • Built multiple regression models in R to forecast yield curve movements, evaluating model performance and achieving a 10% improvement in out-of-sample predictive accuracy
  • Integrated OpenAI APIs into R workflows to automate financial data interpretation, reducing analysis time and enabling faster insights for research projects
  • Taught Statistics I & II and Excel to 9 undergraduate students, designing quizzes and hands-on exercises to simplify complex concepts and improve comprehension

Tools & Technologies: Python, R, Excel, OpenAI APIs, Statistical Modeling

Data Analytics Intern

September 2023 - May 2024
Alfa Bank, Moscow, Russia

Worked as a data analytics intern supporting multiple internal bank departments as clients, including Business Intelligence, Machine Learning, and Operations teams. The role focused on translating business questions into data requirements, extracting datasets from multiple sources, and ensuring data quality throughout the analytics process.

Key Contributions:

  • Served as a liaison between internal clients and data sources, partnering with BI, Machine Learning, and Operations teams to clarify analytics requirements, extract datasets using SQL, and validate outputs in Excel to ensure accuracy, regulatory compliance, and data quality
  • Built data validation rules and quality monitoring dashboards to proactively detect inconsistencies across multiple data sources, reducing process inefficiencies by 20% and improving reliability for model evaluation workflows
  • Standardized the data request process by creating Jira and Confluence templates defining purpose, scope, users, and requirements, improving communication and increasing assessment efficiency by 15% while strengthening compliance
  • Developed executive reports and onboarding materials documenting processes and best practices, reducing new employee training time by 30% and improving knowledge transfer

Tools & Technologies: SQL, Excel, Jira, Confluence, Data Validation, Dashboard Development, Process Documentation
