Worked on the ISS-PCB repository to enhance component library management and streamline schematic design using KiCad. Delivered two features: a TVS diode library update that added new libraries, footprints, and a 3D model to improve PCB design accuracy and manufacturability, and a schematic simplification for the MIDAS-MK2 board by removing eMMC capacitors and an ADC expander to align with related projects. Focused on reducing bill of materials complexity and schematic clutter, these changes supported faster design cycles and better cross-project alignment. The work demonstrated attention to detail in PCB design and effective use of component library management within KiCad.
