Biography

Hi, I'm Jiageng Li. Tongji Univ. CS/IS => Fudan Univ. SE Lab PA Group (2022-2025 expected).
My aspiration is to become a qualified software developer. Given my focus during my internship and graduate studies, I'm also interested in engineering efficiency and program analysis, and my other dream is to become someone who masters all the effective program analysis techniques in the world.
Additionally, You might not believe that I got 1st Prize(60/2000000+) in the Final of 12th SSSCCC, aka "Secondary School Student Creative Composition Competition".
