Founder at Kode Java

Hi, I'm a passionate programmer based on the beautiful island of Bali. I specialize in Java, with hands-on experience in Spring, Hibernate/JPA, and MySQL. I'm currently working on a project I care deeply about, and your support—big or small—helps fuel my work (and my coffee ☕️).

If you like what I’m building, consider buying me a cup of coffee. Thanks a lot!
