About

Hi, I’m Yi, a Master of Computer Science graduate (GPA 6.8/7.0) with a passion for building scalable, end-to-end web applications. I specialise in bridging the gap between sophisticated backends and intuitive frontends.

With hands-on experience in Java (Spring Boot), Node.js, and React/Next.js, I have successfully delivered projects ranging from secure voting systems to real-time multiplayer platforms. I am proficient in managing the entire software development lifecycle, including deploying production-ready apps to cloud platforms such as AWS and Railway.

I pride myself on writing clean, maintainable code and solving complex technical challenges. Check out my latest work and live demos at portfolio.wyprojects.com. Let’s collaborate to turn your ideas into high-quality digital products!
