During November 2024, Drabaioli developed and delivered the SdraKb00 keyboard firmware in the srwi/qmk_firmware repository, focusing on embedded systems and C programming. The work introduced a 3x4 macro pad with hot-swappable keys, RGB backlighting, and layered keymaps to support both base and function layers. Drabaioli implemented layer-switching logic and numpad functionality, enabling users to toggle between layouts efficiently. The firmware provided visual feedback by varying RGB matrix colors according to the active layer, enhancing usability. All changes were traceable to a single commit, reflecting a focused engineering effort with depth in keyboard firmware development and embedded C.
