This is me
Hi, I'm Koen.
I'm a frontend developer with experience in building web and mobile applications using React, React Native, and Angular. My work focuses on creating responsive and user-friendly interfaces.
I prioritize delivering optimal user experiences by considering the audience's needs and project requirements. Currently, I'm expanding my expertise in React and JavaScript to become a full-stack React developer and mentor others in the tech community.
Beyond coding, I enjoy playing the piano, baking, cooking, and gaming. I also stay updated with the latest tech developments by watching YouTube and following tech news.
