I'm a long time Debian user (potato/woody era), using it on most devices I own (servers, laptops and phones). Debian save me a lot of time, so I wanted to find a way to give back. I started contributing by providing patches to u-boot-menu in order to bring support to modded Pinephone on Debian/Mobian which required using dtbo. And after I started packaging tools needed to support sensors (hexagonrpcd) or VoLTE (81voltd) on Qualcomm SoC under the Debian-on-Mobile team.
I would like to continue bringing more support for phone/embedded devices in Debian.
