Hi, I'm Jaehyun

Hi, I'm Jaehyun — a Backend Developer

I build backend services with Java, Kotlin, and Spring Boot. My interests include backend architecture, data processing, real-time communication, authentication and authorization, and infrastructure operations.

I aim to turn service requirements into reliable systems and working features, and contribute to open source through bug fixes and testing.
