About
Daniel Crouse is the founder of QualityEngineer.ai. He built the platform after spending 15+ years working in supplier quality, PPAP documentation, and manufacturing quality systems, and seeing firsthand how much engineering time gets swallowed by manual documentation and disconnected spreadsheets.
QualityEngineer.ai is the result: an AI-powered quality engineering platform that connects APQP, PPAP, PFMEA, Control Plans, CAPA, and statistical tools in one traceable workflow. The goal is to give quality engineers their time back so they can focus on the actual engineering problems, not the paperwork.
Daniel writes about PPAP, APQP, IATF 16949, supplier quality, and how AI is changing the manufacturing quality landscape. His writing is grounded in real project experience, not theory.
