Hire the Best Mechanical Designers
in Mexico

I’m a mechanical designer with hands-on experience developing 3D models and 2D drawings for manufacturing, assembly, and custom automation systems. I specialize in helping small and mid-sized companies bring their mechanical ideas to life — from concept to production. • Skilled in SolidWorks, technical drawings, GD&T, assemblies, and optimization • Experience with custom design for welding, assembly, and manufacturing fixtures • Fast response and reliable communication throughout your project • Mechanical Design + Documentation + Optimization = Delivered I ensure each design meets the client’s needs and remain available after delivery for any necessary adjustments at no extra cost. Let’s work together to turn your technical challenges into efficient and manufacturable solutions.

I help non-technical founders, inventors, and entrepreneurs turn rough ideas into functional, manufacturable mechanical prototypes. If you have an idea, sketch, or concept but don’t know how to turn it into a real product that actually works — that’s where I come in. I focus on function first: Parts that assemble correctly Designs that can be prototyped (3D printing / basic manufacturing) Practical engineering decisions, not just “nice-looking” CAD You don’t need to speak engineering. I translate your idea into a working mechanical solution. Typical projects I work on: Early-stage product prototypes Mechanical parts that don’t fit or don’t work as expected Improving manual or inefficient physical processes Design fixes before manufacturing What you get: Clean, functional CAD models Assembly-ready designs Engineering thinking behind every decision Clear communication, no unnecessary meetings If your goal is a prototype that works in the real world, not just on screen I can help
