From 2009 to mid 2018, all through those years I mainly focused on doing device driver and virtualization development based on open source software. I have experience on different products (data communication, application delivery controller, and mainframe), CPU architectures (MIPS, x86, and Z) and operating systems (Linux and FreeBSD).I worked with my coworkers and the community making vfio-ccw upstreamed in 2017. Then I took the co-maintainer role of vfio-ccw in the Linux Kernel counterpart. Other than writing code, I tried to give back to the community by reviewing the others' code.Since 2018, I worked as senior software engineer in Innovation Lab, Cloud BU, Huawei. To build next generation IaaS, based on self-design servers and smart NICs, I mainly took the responsibility to push network related functionalities (both control plane and data plane) offloading project.I enjoy doing technical work, and I think open source is cool.
