Hello, I'm Ruben. I'm a Software Engineer with 4 years of experience. I enjoy building sites & apps. My focus is React and Node.js.
About me
When I first started coding in PHP, I discovered my passion for web development. I was captivated by the idea of creating something myself and making it accessible all around the world. So I started working on my web developer skills while studying and, by the time I was graduating, I was already working as a full-stack developer. My main stack is React, Node.js and MongoDB. I also like to program in Arduino and make mobile apps. I am currently seeking a full-time position as a software developer.
When I'm not coding, I enjoy playing the guitar, reading books, playing video games or working on my motorcycle. I also like riding to the countryside to relax and enjoy the views.
