关于 About
我是耿泽浩。北京大学电子与通信工程硕士，工程师，中级经济师。曾在美团、滴滴、SUTD-MIT IDC 等机构从事算法研发，2021 年定向选调至中共保定市委组织部，2023 年 12 月入职中信国安实业集团有限公司。
站点名「初心」，提醒自己做事善始善终。这里也保留着早期爬虫、数据与工程实践的笔记。
Stay hungry, Stay foolish.
I'm Zehao Geng, M.Eng. in Electronics & Communication Engineering from Peking University—engineer and intermediate economist. I've worked on algorithms at Meituan, DiDi, and SUTD-MIT IDC; joined the Organization Department of Baoding Municipal Party Committee as a selected graduate in 2021; and have been at CITIC Guoan Industrial Group since Dec 2023.
This site is called 初心 (Beginner's Mind)—a reminder to finish what I start. Early notes on crawlers, data, and engineering still live here.
Stay hungry, Stay foolish.
