ABOUT

Developer

Kim Yungju

I'm Yungju, an undergraduate Computer Science student at the National University of Singapore. I made an intentional pivot from Business and Economics to CS because I wanted to turn ideas into reality through code.

I focus on building AI-powered full-stack applications , from autonomous agents to real-time platforms, using tools like Next.js, Python, and OpenAI. Most of my projects start from a simple question: how can technology make this easier?

Fluent in English and Korean, I bring an international perspective from growing up in Kuala Lumpur and studying in Singapore. Beyond full-stack development, I'm drawn to software engineering and AI engineering, aiming to build systems that are both powerful and intelligent. Outside of coding, I serve as Head of Technology at NUS Developer Group, and I unwind in the pool.
