About this device
I build and maintain OS platform layers, mostly kernel-adjacent services and the update pipeline that ships them. Over 9 years I have cut cold boot time on our reference board by 41% and kept a fleet of roughly 2.3M devices on staged OTA rollouts with a rollback rate under 0.4%. I read logs faster than I read novels, which my partner has opinions about.
