I'm a mechanical product engineer specializing in injection-molded enclosures and housings — helping hardware entrepreneurs get from concept to factory-ready files without DFM surprises derailing their timeline or budget. My work bridges the gap between concept and production, designing parts that account for tolerances, materials, assembly, and manufacturing processes from the start, so what gets approved in CAD is what actually gets built. I partner with hardware entrepreneurs and product teams who need designs that are practical, reliable, and ready for production — not just visually polished.
Many projects fail or stall not because of bad ideas — but because the design wasn’t grounded in real-world constraints.
I don’t approach projects as a CAD operator. I approach them as a product engineer.
That means thinking through:
-How parts will be manufactured
-How they will be assembled and serviced
-How tolerances stack up
-How the product will be handled, stressed, and used over time
The goal is simple: fewer revisions, fewer surprises, and a smoother path to production.
I specialize in injection-molded enclosures and precision mechanical components, including: -Electronic and hardware enclosures -Injection-molded housings and components -Mechanical parts and assemblies -CNC-machined parts -Reverse-engineered parts and Scan-to-CAD workflows All deliverables are clean, fully parametric SolidWorks files — structured so they can be modified, quoted, and manufactured with confidence.
I keep the process straightforward and collaborative.
1.Understand the product
Use case, constraints, target manufacturing method, and goals.
2.Design with manufacturing in mind
Geometry, tolerances, draft, wall thickness, assembly logic.
3.Deliver production-ready CAD
Clean feature trees, clear design intent, and manufacturable geometry.
I’m comfortable stepping in early during concept development or later to fix, refine, or reverse-engineer existing designs.
-Hardware entrepreneurs developing products that need to be injection-molded and manufactured -Product teams preparing for manufacturing -Companies that need reliable, factory-ready CAD -Teams that want to avoid costly DFM surprises and design rework If you're looking for branding, graphic design, or concept art only, I'm likely not the right fit.
