About

I’m a multidisciplinary Architectural and Mechanical CAD Designer with expertise in 2D drafting, 3D modeling, rendering, and engineering documentation. I provide complete design and drafting services for buildings, products, and mechanical systems — from initial concept to construction or manufacturing-ready drawings.

With years of experience in AutoCAD, Revit, SolidWorks, SketchUp, and Inventor, I help clients turn their ideas into accurate, efficient, and visually compelling CAD deliverables that meet both design intent and real-world requirements.

🧱 Architectural Design Expertise
- Full architectural drafting: floor plans, elevations, sections, and details
- 3D modeling and visualization of residential and commercial structures
- BIM modeling and coordination (Revit, ArchiCAD)
- Exterior and interior rendering (Lumion, Enscape, V-Ray)
- Site planning, layout optimization, and construction documentation
- Conversion of sketches or PDFs into accurate CAD drawings
- Energy-efficient and code-compliant design support

⚙️ Mechanical Design Expertise
- 3D mechanical modeling and detailed assembly design (SolidWorks, Inventor)
- 2D manufacturing drawings with full GD&T and BOM
- Sheet metal design, product casing, and component detailing
- Design for Manufacturing (DFM) and reverse engineering
- Virtual prototyping and simulation-ready models
- 2D-to-3D CAD conversion for legacy parts or drawings

🧩 Software Proficiency
- AutoCAD | Revit | SolidWorks | Inventor | SketchUp | Fusion 360
- Rendering: Lumion, Enscape, V-Ray, Photoshop
- Documentation: PDF, DWG, STEP, STL, DXF, RVT, SKP

🧠 Core Strengths
- Strong cross-disciplinary understanding of architectural and mechanical systems
- Precision drafting and adherence to standards (building code, GD&T)
- Excellent communication and fast turnaround on design revisions
- Ability to collaborate remotely with architects, engineers, and fabricators
- Clear, organized drawing sets ready for permit or production

📦 Services Offered
- 2D CAD drafting and 3D modeling
- Architectural visualization and rendering
- Mechanical design and assembly documentation
- Conversion of hand sketches or PDFs into CAD files
- Prototype design, visualization, and manufacturing drawings
- Full design-to-documentation service package

🚀 Work Process
- Review your project scope and requirements
- Provide a clear proposal with cost and timeline
- Develop 2D/3D models, drawings, and renderings
- Revise based on your feedback
- Deliver final files ready for construction or manufacturing
