UHP systems specialist, from BIM model to first weld
High-Purity Piping Specialist & Orbital Welding QA/QC Technician
With over 15 years of experience in mechanical engineering, I specialize in Ultra-High Purity (UHP) gas distribution systems for laboratories and semiconductor manufacturing facilities. My expertise spans the complete lifecycle from design and BIM modeling through fabrication, installation, and QA/QC validation.
Currently leading piping design for KAUST's Interdisciplinary Research Facility (IHP), managing UHP gas networks with material scopes up to $150k. I've developed PipeForge, a custom 3D web platform that automates piping calculations and generates manufacturing-ready deliverables.
My technical foundation includes orbital welding (Orbitalum/Orbimatic), 316L stainless steel metallurgy, cleanroom protocols (ISO 5-8), toxic gas monitoring integration, and project governance via Procore/BIM 360.
