Hello, I'm a full-stack developer who loves building things that live on the web.

// I specialize in Java, Spring Boot, Hibernate and React.

$ cat about.txt

I'm a developer who enjoys tackling complex problems and understanding what makes software tick. Whether I'm coding as a hobby or at work, I find the most satisfaction in deepening my understanding of my tech stack and the fundamental principles, patterns, and architectures behind the software we build. At heart, I'll always be a student first, curious by nature, and eager to learn.

When I'm not coding, you'll find me engaging in many of my other hobies, including tinkering with cars and electronics.
