Message

At McKinsey&Company, I work on a sleep-products e-commerce platform, building and maintaining its frontend with React and Next.js. I create reusable components, integrate REST APIs, and optimize performance.

I also use AI-assisted development tools such as Claude Code, OpenAI Codex, Cursor, Gemini, and Junie to implement features, refactor code, troubleshoot issues, and improve test coverage.

On McKinsey&Company's Corporate Performance Analytics project, I contributed to React and JavaScript micro-frontends that displayed company data through charts, tables, and diagrams. I also maintained and refactored existing code and created new micro-frontends.

At Epam, I worked on Base86, a product for tracking and optimizing supplies costs for independent dental offices. I used React, TypeScript, GraphQL, and other frontend technologies on the product.
