Full-Stack Developer | React, Next.js, TypeScript & Node.js

About

I am a Full-Stack Developer with a strong focus on front-end technologies, specializing in building modern, responsive web applications using React, Next.js, and TypeScript. I love creating intuitive user interfaces that provide seamless experiences while ensuring robust functionality on the server side with Node.js and Express.js.

My journey in web development has taken me from PHP and Drupal to the modern JavaScript ecosystem. I'm passionate about learning new technologies and building scalable applications, with a growing interest in mobile development through React Native. I believe in writing clean, maintainable code and staying up-to-date with the latest industry trends.
