I build scalable full-stack web platforms with React, TypeScript, and modern DevOps practices.
What I'm looking for
At EPAM Systems, I build React and TypeScript interfaces for Disney and Nordstrom, including reusable monorepo component libraries, NPM-ready modules, microfrontend applications, and backend-integrated workflows.
With more than seven years across full-stack development, automation, QA, and support engineering, I've improved application maintainability, optimized MongoDB queries, created Express.js APIs, maintained CI/CD pipelines, and built automated testing solutions. I enjoy exploring new technology stacks, discussing practical methodologies, and solving complex problems with clean, scalable code.
