Hi, I'm Jung Se Young.

I bring ideas to life with code and design.

I'm a Computer Science graduate with a Bachelor's degree, currently working as a freelance full-stack web developer and UI/UX designer. I'm driven by my passion for crafting digital experiences through clean code and thoughtful design. My work spans from building responsive frontends with Next.js and TypeScript to architecting scalable backend systems — always with an eye for detail and usability. Beyond development, I take on UI/UX design projects, turning ideas into intuitive and visually compelling interfaces. Lately, I've also been exploring AI-integrated solutions and always looking for new challenges to push my skills further.
