From Unclear Idea to Useful Engineering Output
Bring the problem as it exists. I help define the right next deliverable, then carry the design toward a decision, prototype, or production handoff.
Build the design
Develop the CAD, assemblies, technical drawings, DFM decisions, and validation visuals needed to move the project forward.
Hand off with confidence
Receive clean exports, supplier-ready documentation, revisions, and a clear list of next actions for prototyping or production.

Creative Vision
I'm a freelance Mechanical Engineer (B.Sc. University of Twente) focused on product development, 3D CAD, DFM, and precision manufacturing.
Before establishing IAEngineering, I spent years at Micronit as a Process Development Engineer and Researcher in the microfluidics sector. There, I developed custom C# intranet systems, optimized CNC machining accuracy to 5-micron assembly tolerances, and slashed an additive manufacturing development timeline from 5 months to just 2 weeks.
Today, I leverage that rigorous engineering background to deliver end-to-end CAD design and 3D visualization — ensuring every product is not only visually striking but technically sound, documented, and production-ready.

Before We Start
Questions Before We Start
A short project brief is enough to work out the right next step.
Can I start with a sketch, photo, or existing CAD?
Yes. A sketch, photo, reference product, or existing CAD file is enough to define the next engineering step.
Do you prepare files for manufacturing?
Yes. Support can include production-ready CAD, assemblies, technical drawings, exports, and DFM review for CNC, 3D printing, and injection molding.
Do you work with international product teams?
Yes. I am based in Barcelona and work remotely with international teams in English, Spanish, and Lithuanian.
