Since May 2025

My role: ProbFun contributor · formed the iMathBook team and led development

This was the first project I contributed to. I poured my passion for product design into it and greatly strengthened my engineering skills through the work. In May 2025, I joined ProbFun, the predecessor of uMathHub. In July, I started an independent branch, formed the iMathBook project team and led its development. Both iMathBook and uMathHub are officially recognized mathematics teaching platforms at BUPT. They are now used in mathematics teaching and have supported more than 1,000 student engagements in total.
