Paul Wieland is a Certified Quality Engineer with over 30 years of hands-on experience and a decade-plus focus on supplier development, Lean/Six-Sigma process improvements, and root cause/data analysis for electronics and PCBA production. He currently leads quality assurance and AS9100 compliance for lighting systems at Rockwell Collins, having previously driven supplier APQP, ISO audits, and process transfers across major industrial electronics providers. Paul combines deep shop-floor expertise—operator/inspector training, rework/repair, and firmware handoff—with a practical maker streak demonstrated by embedded IoT firmware contributions (ESP8266 garage door controller) and front-end improvements to the popular Node-RED project. Known for closing stubborn supplier corrective actions rapidly and for teaching industry-standard workmanship, he blends audit-level rigor with pragmatic manufacturing fixes. Based in Muskego, WI, he pairs formal credentials (CQE, ISO Lead Auditor, Lean Master) with a track record of turning complex quality challenges into measurable improvements.
