Developer from Brazil. I write open-source software, mostly self-hosted tools and low-level Linux work, and I care about privacy and performance.

A Linux driver for Ajazz mice. The vendor's configuration software only runs on Windows, so I captured the USB traffic with Wireshark, reverse-engineered the HID protocol and reimplemented it in C.
- Control DPI, RGB, buttons and macros natively on Linux, from a GTK4 app or a CLI
- No vendor software, no Windows VM
- Built from packet captures and protocol analysis
