Senior🎓
Top SchoolPeng Jun is a Technical Product Manager and former software engineer with 11 years of experience building backend systems and cloud developer tools, currently shaping AI and software architecture at China Telecom from Chengdu. He has a strong open-source pedigree—contributing to high-profile projects like Alibaba Druid and Apache ShardingSphere—where he improved SQL parsing for MySQL stored procedures and added dialect-specific metadata support for PostgreSQL and Oracle. Prior roles at WeChat, Tencent, and Siemens combined product-facing engineering with performance tuning, realtime data systems, and developer efficiency tools. He pairs a Peking University M.Eng. in Computer Technology with hands-on expertise in cloud code repositories and platform tooling (he was responsible for Huawei Cloud’s CodeArts Repo as a senior engineer). Known for pragmatic problem solving, he focuses on robust SQL/database interoperability and test-driven improvements that reduce production surprises. Comfortable spanning product strategy and low-level implementation, he brings both engineering depth and product leadership to complex cloud and AI projects.
