Hi, I’m Junyoung Kim, a backend engineer who loves documenting things.

I primarily work with Java and Spring to design RESTful APIs and scalable server architectures, focusing on building stable and efficient systems that implement core business logic and solve complex problems. I have a deep interest in creating long-lasting software grounded in clean code and solid design principles. My goal is to design systems with maintainability and scalability in mind — building platforms that many people can use for a long time — and to solve various problems through development while providing reliability and value to users.
