In April 2025, Michal contributed to the qmk/qmk_firmware repository by developing per-variant linker scripts for the AnnePro2 keyboard, targeting both C15 and C18 microcontroller variants. This work involved updating and renaming linker scripts to accurately reflect the specific MCU in use, enabling the firmware to leverage the expanded SRAM available on C18 boards. By aligning script naming conventions and improving memory utilization, Michal enhanced repository consistency and maintainability. The project was implemented in C and drew on embedded systems and firmware development expertise, laying a foundation for future optimizations and reproducible builds within the QMK firmware ecosystem.
