About Serj

CAD Engineer | 3D Modeling → Prototype → Production | Laser Cutting DXF | CNC | Reverse Engineering

I bridge the gap between idea and production — from a sketch, photo, or physical part to a fully validated, manufacturing-ready model.
With hands-on engineering training and certification in Germany, I apply German precision standards (ISO/DIN/ANSI) to every project. I don't just model — I validate. Every design I deliver has been tested against real manufacturing constraints: wall thickness, draft angles, bend radii, laser kerf, and tolerances for the specific process.
What makes my workflow different: I have a 3D printer on my desk. Before you approve the final file, I can print a physical prototype, verify fit and function, and iterate fast — saving you costly revisions at the production stage.
My core services:
3D Parametric Modeling (Fusion 360, Blender, SolidWorks) — precise, editable, production-ready STEP/IGES/STL files for CNC machining, injection molding, sheet metal, and additive manufacturing.
Reverse Engineering — rebuild any part from photos, hand measurements, or mesh scans (STL → solid STEP). I reconstruct legacy parts, worn components, and custom fixtures with full dimensional accuracy.
Technical Drawings & DXF for Manufacturing — 2D drawings (PDF/DWG/DXF) with full GD&T, tolerances, surface finish, material notes, and BOM. DXF files optimized specifically for laser cutting and CNC — correct layer structure, closed contours, no duplicate lines.
Laser Cutting & Sheet Metal Preparation — I understand the full laser cutting workflow: kerf compensation, bend allowance, nesting-ready DXF output, microjoint placement, and material-specific tolerances for stainless steel, aluminum, and mild steel.
CNC CAM Programming (Mastercam) — toolpath generation, stock setup, post-processing for 3-axis milling and turning operations.
DFM/DFA Review — I review existing designs for manufacturability before production and flag issues that would cause scrap or rework.

    CAD Engineer | 3D Modeling → Prototype → Production | Laser Cutting DXF | CNC | Reverse Engineering

    I specialize in parametric 3D modeling in Fusion 360 with integrated Model-Based Definition (PMI/GD&T), delivering precise, production-ready designs. With hands-on manufacturing training and certification in Germany, I bring German engineering quality into every project, optimizing parts for CNC machining, injection molding, sheet metal, and additive manufacturing. My work follows DFM/DFA principles and meets international standards (ISO/DIN/ANSI) to ensure smooth production with minimal revisions.

    I provide a complete idea-to-production pipeline: from sketches, photos, or prototypes to fully validated 3D models, technical drawings, and manufacturable prototypes. Clients receive a full package—2D/3D drawings (PDF/DWG/DXF) with dimensions, tolerances, GD&T, surface-finish, material notes, assembly references, and BOM annotations—along with verified STEP/IGES/STL files ready for suppliers and 3D printing. I also offer reverse engineering, rebuilding models from measurements, photos, or mesh scans (STL → solid), and provide thread, insert, and fastener integration as needed.

    For visualization and presentation purposes, I create photorealistic renders and simple animations to showcase the final product. All work is checked for ISO/DIN/ANSI compliance, including wall thickness, draft angles, and clearance validation, ensuring reliability from design to production.
