Hi 👋, I'm Jinhua Luo.

A passionate backend developer from China

• 🔭 I am currently an independent Postgresql and Nginx technical consultant.

• 🌱 I’m currently learning eBPF, k8s, and cilium.

• 👨‍💻 All of my projects are available at https://github.com/kingluo

• 📝 I regularly write articles on http://luajit.io

• 💬 Ask me about Postgresql, Nginx, Openresty, Luajit, Envoy, or anything you like.

• 📫 How to reach me luajit.io@gmail.com

• 📄 Know about my experiences https://github.com/kingluo/myresume/blob/master/README.md

• ⚡ Fun fact I like watching David Lynch and Quentin Tarantino movies.

I think experience is not the most important asset, but the ability to learn and innovate. My career is very long, and I am faced with a lot of knowledge. If I just learn and memorize knowledge, I cannot maintain my professional advantage. When I encounter a problem to overcome but have no clue, I like to go back to the essence of the matter to rethink, jump out of the existing framework, and escape the shackles of experience. Facts have proved that this has helped me achieve success again and again.

Reflection is the biggest difference between humans and animals.
