Software Developer

I build software, learn deeply, and keep growing beyond code.

I'm Yaren Kaplan, a software developer focused on Java, Spring Boot and backend development, while continuously expanding my skills in cloud technologies, DevOps and full-stack development.

Currently

Going deeper, not just wider.

My current focus is building a stronger foundation in Java and backend development, while understanding the technologies around them more deeply rather than simply collecting tools.

I’m especially interested in understanding why systems behave the way they do — from application structure and database relationships to security, deployment and software architecture.
