GoIM is a distributed instant messaging solution based on Golang and RocketMQ. It’s a high performance and high availability solution. I’ve developed GoIM in 2021 and it’s still under development. It has passed the basic IM tests, but it still needs a lot of work to be done. My main purpose of developing GoIM is to learn distributed system and Instant Messaging. I’ve occurred a lot of problems during the development of GoIM and I’ve fixed most of them. It means I’ve learned something and improved my skills.

OSS Contributions

I'm a huge fan of open source software and I try to contribute back to the community as much as possible. Here are some of my recent
