@krisztinmegyesi

Full Stack Software Engineer at EPAM who deployed serverless AWS infrastructure and built responsive TypeScript and React.js interfaces.

At EPAM, I architected dynamic interfaces with TypeScript and React.js, using TanStack Query to optimize client-side state and eliminate redundant network fetches. I also designed and deployed serverless AWS infrastructure to support fault-tolerant horizontal scaling.

At NDA, I delivered cross-platform mobile functionality with React Native and Node.js, and integrated real-time push notifications. I also established JWT authentication flows and built real-time data feeds with WebSockets.
