Hi, I am Chang Lee, a Full Stack Web Developer. Growing up, I have always had a passion for crafting and building projects. This journey began with simple materials like paper to legos and eventually evolved to embrace the technologies of the real world via the Arduino. However, the path to continue this journey often required me to devise strategies for saving money to afford future projects.

This dynamic shifted completely after my introduction to Scratch at a camp hosted by MIT. There, I discovered the boundless potential of projects I could bring to reality without the constraint of financial resources. Ever since that pivotal moment, my journey of innovation has continued and I still enjoy building meaningful products that help benefit society till this day.

As of present, I am seeking entry-level software engineer or data engineer positions. Scroll for my work experience below, which consists of part-time positions and full-time internships.
