The open-source work is a habit rather than a portfolio — none of it is production, and none of it was paid for. Mostly xtreader, an e-reader system: firmware for the Xteink X4, a sync server on Cloudflare Workers, a React dashboard, and plugins for KOReader on jailbroken Kindles. Books, reading position and sleep-screen wallpapers stay in sync across every reader on one account.
