At Epam Systems, I developed Node.js and TypeScript microservices on AWS and worked on React.js microfrontend applications focused on modularity and reusability. I also used Claude Code to support development workflows and automate repetitive coding tasks.

At Nexus, I worked on a fintech application with a microservices architecture and AWS services. I added integration testing to the project from scratch, wrote unit tests, and integrated third-party services and APIs.

At EPAM Systems, I implemented a GraphQL data abstraction layer for direct MongoDB calls to optimize performance. I also discussed the migration with the team and communicated with the customer development team to understand its internal tool.

I hold the AWS Certified Cloud Practitioner certification. My work has included REST and GraphQL APIs, testing, and deploying and managing microservices in AWS.
