About

Hi, I’m Maksym Voloshyn, a Frontend / Fullstack Developer with a passion for building high-performance fintech and trading web applications. I specialize in scalable UI architectures and real-time data streaming, leveraging WebSockets to deliver up-to-the-moment updates in trading interfaces. I enjoy modernizing legacy systems with React, Next.js, and TypeScript, and I thrive in fast-paced environments that demand clean code and solid architecture.

Beyond UI, I bridge frontend and backend with Node.js services, and I deploy applications using AWS and Docker. I continuously optimize performance with lazy loading, code-splitting, and SSR, and I value teamwork, testing, and accessible design. I also explore AI-assisted development tools to accelerate debugging and delivery.
