Ezvenigo designed and delivered the initial LED_DEMO PCB hardware for the formulaslug/fs-3-intro-projects repository, establishing a reproducible baseline for hardware prototyping. Their work involved schematic capture and PCB layout using KiCad, applying electronics engineering and hardware design skills to create a functional and maintainable board. To ensure data integrity and support rapid iteration, Ezvenigo implemented a backup artifact strategy, packaging the design files into a ZIP archive and integrating it into the project’s backup directory. This approach enabled reliable recovery and reproducibility for future development. The project’s scope was focused, with depth in hardware design and process reliability.
