About

👋
I’m a fullstack developer who enjoys building thoughtful, end-to-end web experiences—from designing interactive UIs to architecting reliable backend systems. I care about writing clean code, solving real-world problems, and making interfaces that feel good to use.
Right now, I’m working on NibbleAI, a recipe platform enhanced with ChatGPT. It’s a solo project where I’ve been shaping everything from the frontend (Next.js 15, custom Radix UI components) to the backend (PostgreSQL, Docker, AWS). It’s been a great way to push my skills in both infrastructure and product design.
Before this, I contributed to AI research in digital pathology and trained deep learning models to predict cancer-related genetic mutations. I also served in the Korean Air Force, leading training programs for heavy vehicle operations—an experience that taught me a lot about structure, leadership, and staying calm under pressure.
Lately, I’ve been delving into Swift and SwiftUI to create some fantastic utility apps. One of these apps I’m working on helps you keep track of your subway position and promptly alerts you when you reach your destination 🙂
