Hi, I’m Siqi Li, a computer science graduate passionate about creating performant and accessible web and mobile solutions. I’ve gained hands-on experience in full-stack development, working with React, Express, and REST APIs, and enjoy debugging and collaborating within teams to deliver clean and maintainable code.
I have also developed iOS applications using React Native and Expo, as well as built machine learning models from scratch using Python and NumPy. I’m dedicated to learning and applying my skills in web and mobile app development and machine learning to make an impact in technology.
