Modern JavaScript Expertise

As a JavaScript developer, I leverage the full power of modern ES6+ features to build dynamic, performant web applications. From frontend interfaces to backend services with Node.js, I create solutions that are both elegant and efficient.

My expertise spans the entire JavaScript ecosystem, including asynchronous programming, functional programming paradigms, module systems, and modern tooling. I write clean, maintainable code that follows best practices and industry standards.
