About

I am a Quality Assurance Professional with over a decade of experience in managing complex industrial processes and quality systems. My current focus at Siemens involves ensuring product safety and driving excellence through systematic problem-solving in high-standard manufacturing environments. ​Instead of just following procedures, I prefer to bridge the gap between technical requirements and operational reality. My approach is rooted in a deep understanding of engineering principles, which allows me to navigate the entire quality lifecycle—from dissecting customer complaints via RCA/8D methodologies to leading high-stakes audits. ​My core expertise includes: * ​Audit & Compliance: Certified ISO 9001:2015 Lead Auditor and VDA 6.3 Supplier Auditor. * ​Technical Coordination: Serving as an International Welding Engineer (IWE), overseeing WPS/PQR processes and NDT controls. * ​Risk & Strategy: Moderating FMEA/PFMEA sessions and leading product safety risk assessments. * Operational Excellence: Using Lean Six Sigma tools to monitor quality KPIs (DPU/PPM) and reduce non-conformance costs. ​I value proactive risk management and believe that a strong culture of quality is the backbone of any global organization. I enjoy working in task-force-driven environments where precision and strategic improvement are non-negotiable.
