About Me
I'm a passionate software developer with over 3+ years of experience building web applications and digital products. I specialize in Java, JavaScript, TypeScript and React.

When I'm not coding, you can find me playing handball, researching about finance, or experimenting with new technologies. I believe in continuous learning and sharing knowledge with colleagues and friends.
