Yongfeng Gu is a senior software engineer at Ant Group, Hangzhou, China (2021-now). Ant group aims to build the future digital infrastructure of services, and thereby bring about constant and incremental changes that are beneficial to the world. The famous products include Alipay, OceanBase, and AntChain.

Before that, he obtained a Ph.D. degree in computer science at the School of Computer Science, Wuhan University, China in 2021. He was also a member of CSTAR - Centre of Software Testing, Analysis, and Reliability (2016 - 2021). His current research directions include machine learning, intelligent optimization, marketing, and user growth. Any cooperation is warmly welcomed, please contact me at LinkedIn, ResearchGate, CSDN, and GitHub.

2. Software Crash Analysis

Software crash refers to an unexpected termination of software systems. Developers spend much time and effort in dealing with software crashes. In this project, we mainly focus on crash reproduction, localization, repair, and other relative tasks.

3. System Performance Analysis

Modern software systems often provide tons of configuration options to extend flexibility and functionality. However, the daily-increasing number of options brings challenges in two vital tasks: configuration-related bug detection and system performance optimization. In this project, we tried to explore solutions to solve or assist with the above tasks.
