I used to be one of the core team members of custom android ROMs like PixelExperience and Evolution X. I mainly worked on the following devices when I was active in the community.
- polaris (Xiaomi Mi Mix 2s)
- venus (Xiaomi Mi 11)
I am no longer maintaining AOSP builds officially for any devices because I have to fucus on real life situations. I am daily driving an OnePlus 13 right now, but I will unlikely be releasing new builds regularly like I used to. I do still follow the latest news of AOSP, and I might make improvements to the devices I own from time to time.
All of my work on AOSP is open source and will always be open source. You can find my old device and kernel trees on the PE devices archive and on my personal GitHub.
