Hi， I’m TT.
I have been engaged in embedded Linux development for 12 years, mainly in the field of network equipment. The development technologies involved include Linux C, Linux kernel, OpenWrt system, Python etc.
I developed a parental control plug-in based on OpenWrt. The plug-in is completely open source and currently has 2K stars. The plug-in uses the 7layer protocol recognition of the Linux kernel and can accurately analyze user traffic(DPI). For example, it can recognize YouTube, Facebook, WhatsApp, etc., and count the app access time.
I am also developing more openwrt related software. If you are interested, you can follow me on github.

大家好，我是TT。
从事嵌入式Linux开发多年，主要是网络设备方向，涉及开发技术有Linux C、Linux内核、OpenWrt系统、Python、javascript、Lua等，精通Linux内核协议栈、防火墙。
基于OpenWrt开发了应用过滤(OAF)插件，该插件完全开源，目前已经2K star，成为了软路由必装的热门插件，使用用户1w以上，该插件可以通过路由器控制小孩上网行为，防止小孩沉迷游戏，比如可以禁止小孩玩王者荣耀、刷抖音等，但聊天不影响。
