Hi, I'mUijin LimSoftware Engineer

Passionate about building technology that solves real-world problems

About Me

I am an Undergraduate Student pursuing a Bachelor of Science in Informatics at the University of Washington, with a concentration in Software Development and Data Science. I have a strong foundation in data structures and algorithms and a deep interest in full-stack development and machine learning.

Through internships, coursework, and hackathons, I've developed solutions ranging from Google Maps-based full-stack services to EV battery defect prediction models. These diverse projects have enhanced my technical versatility and deepened my commitment to delivering impactful, real-world solutions.

Outside of school and code, I enjoy hiking, playing soccer, cooking, and traveling. I'm always eager to grow through continuous learning, feedback, and collaboration. Feel free to reach out, I'd love to connect!
