> Fixed-price schematic review for hardware teams, before layout. A principal-level board designer with 30 years of shipping hardware reviews the schematic and returns a severity-rated report where every finding names the designator or net and the datasheet or engineering-rule reason. Engineer-led, tool-assisted. US LLC (California); serves US, global and Korean teams (Korean-language support, KRW payment).
