PCB designer with a background in industrial automation and embedded systems. I specialize in turning client requirements into manufacturable hardware efficiently, whether that's a new design from scratch or a fast, precise fix to something already built. I work independently across the full process: scoping the requirement, schematic design, layout, and staying in clear communication with the client throughout. I'd rather ask a clarifying question upfront than guess and have to redo work later. If you need a board designed or an existing one fixed fast, happy to take a look.
