My name is Jiaxiao (Joe) Zhou, and I also go by Mossaka. I love building things that make developers' lives easier 💙.
I'm currently working at Microsoft's Azure Container Upstream team as a Software Engineer. Here are three tags that say a lot about my career
- Open Source
- WebAssembly
- Rust
I'm a maintainer of Containerd's Runwasi project and SpinKube, both of which advance the state of the art for WebAssembly (Wasm) running on Kubernetes. I am also a Recognized Contributor to the Bytecode Alliance, contributing to projects like wit-bindgen, wasm-tools, and go-modules. I co-organize the Bytecode Alliance SIG Guest Languages Go Subgroup, where we discuss integrating Go with WebAssembly.
Outside of work, I am probably best known for running online meetups that focus on distributed systems, databases, operating systems, and emerging cloud-native technologies.
Below are a few activities that you may find interesting:
