Hi, I’m Jeffrey. I’m a developer based in Tianjin, China, who’s naturally curious and loves diving deep into how things work under the hood
I spend most of my time:
- Writing clean and efficient code (mostly C++)
- Exploring how databases like PostgreSQL work under the hood
- Experimenting with system design, storage engines
This site is a record of my technical journey, powered by Hexo + NexT.
Feel free to reach out.
