Hi there 👋

I built operating systems in Rust:

rCore: A Linux-compatible kernel for OS teaching. (2018-2019)
zCore: A reimplementation of Zircon microkernel in Rust. (2020)
Occlum: A multi-process library OS for Intel SGX. (2019)

I also built storage systems in Rust:

MadFS: A benchmark-oriented burst buffer file system for IO500. (2020)
MadFSv2: A more "serious" distributed file system but rarely works. (2021-2022)

I'm interested in building distributed systems in Rust:

Madsim: A FoundationDB-style deterministic simulation framework in Rust. (2021-now)

I’m currently working on building database systems in Rust:

RisingLight: An OLAP database system for educational purpose. (2021-now)
RisingWave: A next-generation streaming database in the cloud. (2022-now)
