Mechanical CAD design specialist with hands-on experience converting, repairing, and creating STEP, IGES, and native SolidWorks files. I turn broken or corrupted CAD data into clean, usable models, and rebuild parts from scratch when files are missing entirely. My focus is Reverse Engineering CAD, turning photos, sketches, or physical samples into accurate, manufacturing ready 3D models and detailed technical drawings. Precision, clear communication, and fast turnaround on every project, always.
