Rockstar🎓
Top SchoolChengyun Zuo is a former software engineer and algorithm educator with six years of industry experience at companies including Amazon, GrowingIO, Baidu, and IBM, now working as a freelancer and focusing on screenwriting. He authored the popular 程序员代码面试指南 and built widely used free algorithm and data-structure courses (algorithmbasic2020 and algorithm-primary) with extensive implementations from union-find and Dijkstra to Huffman trees and bitwise tricks on GitHub. Trained at the University of Chicago (CS) and Huazhong University of Science and Technology, he blends rigorous academic foundations with practical backend development experience. Although he now says he’s left programming, his open-source teaching materials continue to help many newcomers master core algorithms and interview skills.
