Stanislav Z.

80+ CAD projects delivered on Upwork, 9,000+ hours, 100% Job Success. I turn ideas, sketches and legacy files into production-ready 3D models and 2D drawings your shop can build from. What I deliver: • 3D parts and assemblies in SolidWorks, Autodesk Inventor, AutoCAD, Pro/ENGINEER (Creo) • Manufacturing drawings with dimensions, tolerances, BOMs and STEP files • Sheet metal (laser cutting, bending), weldments, machined and 3D-printed parts • Reverse engineering from photos, sketches, scanned PDFs and physical samples • Design changes and cleanup of existing models Typical work: structural platforms and stairs, piping and plant rooms, material handling equipment, gearboxes and mechanisms, clamping fixtures, injection-moulded plastic parts. Background: engineering degree in process equipment design, 3 years at an industrial machine-building plant coordinating suppliers and manufacturing, then 10+ years in CAD, including 6 years testing engineering software (SOLIDWORKS, AMD ProRender, Epic Games tools), so I know these programs inside out. Send me your sketch, file or idea. I'll reply with questions, a time estimate and a fixed quote. QA & validation: I also have hands-on QA experience on CAD and graphics software (SOLIDWORKS, Modo), including test design, regression testing, bug reporting and AI-assisted QA workflows. I can review drawings and CAD datasets against standards, validate labeled data for automated design checks, and help improve your QA process.
