Hands-on engineering support for hardware startups and SMEs.
I bridge the gap between
initial concept and scalable manufacturing.
I help founders and CTOs who need a senior engineer without hiring full-time. My focus is on speed, cost awareness, and risk reduction.
Pre-seed to Series B. Moving from functional prototype to DFM ready.
High-reliability systems requiring validation and precision.
Modernizing products or solving manufacturing quality issues.
Led the complete industrialization phase for a high-performance drone platform. Optimized mechanical robustness for mass manufacturing, established the global supply chain, and coordinated with Asian suppliers to ensure precision tolerances were met at scale.
Managed early-series manufacturing oversight for a Class II medical device. Conducted rigorous material selection, oversaw verification/validation builds, and ensured full compliance with medical ISO standards during the transition from prototype to pilot production.
Executed comprehensive DFM analysis and cost reduction strategies for high-volume consumer goods. Optimized plastic injection molding parameters and realized a multi-cavity tooling strategy that reduced per-unit manufacturing costs by 20%.
Engineered complex industrial machinery assemblies combining CNC machined and sheet metal components. Streamlined the assembly process for factory readiness, resolving tolerance stack-up issues and improving serviceability for end-users.
Senior Mechanical & Industrial Engineer | +15 Years Experience
Based in Switzerland, working with projects across Europe & Asia.
My background spans aerospace, medical devices, robotics, automotive, and consumer sports equipment. I don't just design theories; I build products that work in the real world.
Expertise: Plastic injection molding, CNC machining, tooling, DFM/DFA, supplier selection, and cost engineering.
I have led engineering teams, coordinated with external manufacturers in Asian ecosystems, and advised multiple hardware startups from concept to production.
Let's discuss your engineering challenges and how I can support your roadmap.
