About this gig

Does your product face the "manufacturing wall"? From Madrids startups to the Basque Countrys heavy industry, a beautiful model is useless if it cannot be produced efficiently.


I am a Product Engineer specializing in Design for Manufacturing (DFM), ensuring your vision becomes a profitable, high quality reality by turning technical constraints into competitive advantages.

  • CNC Machining Analysis: Simplifying geometries to reduce tool changes, machine time, and production costs.
  • Cost-Reduction Engineering: Identifying expensive design flaws before they reach the factory floor to protect your margins.
  • Material Selection Science: Technical guidance on high performance, sustainable resins or alloys suited for EU markets.
  • Assembly Logic (DFMA): Reducing part counts to streamline your Spanish production lines.


Tools: SolidWorks · Fusion 360 · Moldflow · CATIA · Ansys · KeyShot.


Stop wasting budget on failed prototypes. Lets engineer a product optimized for the modern manufacturing market.
