Quality, Manufacturing & Logistics Consultan | Lean, WMS/ERP, ISO 9001

Struggling with customer complaints, inventory that doesn't match your system, or an upcoming ISO 9001, IFS or CTPAT audit? I help manufacturing and logistics operations fix these problems with hands-on, practical consulting. I'm an Industrial Engineer with 20+ years of experience in electronics, automotive, telecommunications and logistics operations, including roles at Flex, GNS Packaging, Amphenol Network Solutions and Expressway Global Logistics. Some results from my past work: • Reduced customer complaints by 80% for global technology customers using 8D and corrective action plans • Raised inventory accuracy from 60% to 90% (DMAIC, demand planning) and expanded warehouse capacity by 75% (layout redesign, racks, Kanban) • Implemented a WMS and migrated a full site in 2 weeks, increasing storage capacity by 60% • Validated 10 strategic suppliers across Mexico, USA, Canada and China in 4 months and cut aged MRB inventory by 80% • Led a 4-month ERP/WMS implementation and achieved ISO 9001:2015, IFS Logistics (89%), CTPAT, Bonded Warehouse and IMMEX certifications. HOW I CAN HELP Quality & Manufacturing: root cause analysis (8D, DMAIC), corrective actions, NPI and technology transfer (FAI, PFMEA, QCP), supplier quality, ISO 9001 and IATF readiness. Logistics & Warehousing: warehouse layout and capacity, inventory accuracy, WMS/ERP implementation, site migrations, trade compliance (CTPAT, IMMEX, Bonded Warehouse). Process Improvement: Lean and Six Sigma (Green Belt certified), KPI design (OTD, yield), cross-functional project leadership. HOW I WORK Native Spanish speaker and bilingual in English, based in Guadalajara, Mexico (UTC-6). I work hourly, with a clear scope up front and regular written updates, so you always know where the project stands. Send me a short description of your situation and I'll tell you honestly whether I can help and how I would approach it.
