​Senior Product Development Engineer | 10+ Years Bringing NPI Ideas to Market | CAD, DFM & Prototyping
​
Are you looking to turn a complex product concept into a market-ready, scalable hardware reality?
​With over 10 years of experience in end-to-end product development, I help startups, innovative brands, and established companies engineer reliable hardware and consumer devices from scratch. I bridge the gap between initial napkin sketches, high-precision 3D CAD modeling, and factory-line production.
​Core Expertise:
​Concept to Prototype: 3D CAD modeling (SolidWorks, Fusion 360), rapid 3D printing, CNC prototyping, and functional testing.
​Design for Excellence (DFX): Deep expertise in Design for Manufacturing (DFM) and Design for Assembly (DFA) across injection molding, sheet metal, and CNC machining.
​Manufacturing & Sourcing: Supplier management, tooling oversight, BOM cost optimization, and transition to mass production (NPI).
​Problem Solving: Engineering analysis, material selection, mechanical enclosure design, and tolerance stack-up analysis.
​Whether you need a full turn-key design, a critical DFM review before cutting steel tooling, or assistance fixing a manufacturing bottleneck, I deliver production-ready engineering solutions on schedule.
