At Epic Games (EPAM), I build and maintain Node.js and TypeScript backend services for Epic Games' internal KMS and epicgames.com/help. I redesigned REST APIs, cutting response times by 70% across the platform.
I also designed AWS serverless services using Lambda, API Gateway, and DynamoDB, with SNS and SQS for event-driven processing. I built a multi-language CMS with versioned approval workflows across 10+ locales, alongside real-time search and observability.
At MYIA Labs, I built services and data pipelines for a remote patient health-monitoring platform serving 10,000+ patients. I tuned AWS infrastructure to reduce monthly cloud costs by 20% and improved API throughput by 50% through profiling and load testing.
I built an open-source DynamoDB GUI Client, a cross-platform desktop app using TypeScript, Vue.js, Electron, and the AWS SDK. It was adopted by thousands of developers before AWS shipped its official NoSQL Workbench.
