Zvonimir H.

I'm a mechanical design engineer with 15+ years of experience across energy and automotive, with a consistent track record of delivering from CAD to shop floor. My background in electric motors and generators covers the full range — custom designs for cement plants, nuclear backup generators, pump drives, compact hydro units, and rail traction motors up to 10 MW. I've designed from scratch and reconstructed legacy equipment from decades-old archive drawings. I then moved into automotive, working as a Powertrain Systems Design Engineer on high-performance vehicles — complex assemblies, tight tolerances, real production constraints. On Upwork my focus is reverse engineering and 3D modeling: reconstructing accurate models from STL files, point clouds, scanned drawings, STEP files, and partial documentation. I know how to fill in the gaps intelligently and communicate clearly when something is uncertain. What you can expect: clean assemblies and drawings, no silent assumptions, engineering judgment — not just CAD execution. I'm selective about projects. When I take something on, I deliver it properly.
