About

Engineering designs should not only look right on screen—they should work in the real world and be ready for manufacturing.

I’m a Mechanical Design Engineer with 8+ years of hands-on experience in mechanical CAD, product development, DFM, fabrication detailing, and manufacturing documentation. I have been working with SOLIDWORKS since 2017 and hold a Certified SOLIDWORKS Professional (CSWP) certification.

My approach is simple: understand the product, develop the design with manufacturing in mind, and deliver clear CAD data and drawings that a manufacturer can actually use.

🔧 CORE ENGINEERING SERVICES

• 3D Mechanical Design & Product Development
• SOLIDWORKS Part, Assembly & Large Assembly Modeling
• Sheet Metal Design & Flat Patterns
• Structural Steel & Weldment Design
• Manufacturing & Fabrication Shop Drawings
• Reverse Engineering — 2D/3D/Physical Parts to CAD
• Design for Manufacturing (DFM)
• CNC, Laser Cutting & Fabrication Documentation
• 2D Drawings, GD&T, Tolerances & BOMs
• Machinery & Industrial Equipment Design
• Injection-Molded Product Design & DFM
• 3D Printing & Prototype-Ready Models
• DXF/DWG, STEP, STL and Manufacturing Files

🛠️ SHEET METAL & FABRICATION

I create manufacturing-ready sheet metal designs with practical consideration for material thickness, bend allowances, K-factors, bend deductions, reliefs, tabs, slots, clearances, and fabrication methods.

Deliverables can include:

• Accurate flat patterns
• Laser/plasma/waterjet-ready DXF files
• Press-brake and bending drawings
• Fabrication/shop drawings
• Weldment and structural detailing
• BOMs and cutting lists
• Assembly drawings and exploded views

⚙️ MACHINERY & INDUSTRIAL DESIGN

I have experience working on complex mechanical systems and industrial equipment, including machinery assemblies, steel structures, custom trailers, ambulance vehicles, medical equipment, food-processing equipment, and agricultural machinery.

For complex assemblies, I focus on proper design structure, part relationships, interfaces, clearances, serviceability, and manufacturing requirements rather than simply creating geometry.

🔬 PRODUCT DEVELOPMENT & REVERSE ENGINEERING

Whether you have an initial concept, an existing CAD model that needs improvement, a physical component, photographs, measurements, or an old 2D drawing, I can help turn it into a clean and editable CAD design.

My workflow can cover:

Concept → 3D CAD → Design Review → DFM → Prototype → Manufacturing Drawings

I also work with reverse-engineering workflows and can develop accurate CAD models from physical components and 3D scan data.

📐 DESIGN FOR MANUFACTURING

A design can be technically correct and still be expensive or difficult to manufacture. I review designs with the actual production process in mind—whether the component will be laser cut, bent, machined, welded, 3D printed, or injection molded.

I look for unnecessary complexity, difficult features, poor tolerances, assembly problems, manufacturing limitations, and opportunities to simplify the product without compromising its function.

💻 SOFTWARE

SOLIDWORKS | AutoCAD | Autodesk Inventor | CATIA | Geomagic Design X | KeyShot

I can provide professional CAD models, detailed engineering drawings, fabrication documentation, and manufacturing-ready files based on your project requirements.

My objective is not just to deliver a CAD model—it is to deliver a design that makes sense from engineering through manufacturing.

If you have a product to develop, an existing design to improve, a component to reverse-engineer, or manufacturing drawings that need to be created, feel free to send me the project details.

Let’s build it right the first time.

Experience

Research & Development Engineer R&D (Remote) Mauderli AG · Full-time Jan 2024 – Mar 2026 2 yrs 2 mos Schachen, Werthenstein, Luzern, Switzerland Worked remotely with MAUDERLI AG, a Swiss engineering and manufacturing company, providing mechanical design and CAD support for industrial and construction-related products.

My work focused on developing and modifying 3D CAD models, detailed manufacturing drawings, and production-ready designs according to engineering and manufacturing requirements. I worked carefully with dimensions, tolerances, assemblies, and fabrication details to ensure that designs were practical and suitable for real-world production.

Key Responsibilities:

- Creating and modifying detailed 3D CAD models and assemblies in SOLIDWORKS.
- Preparing precise 2D manufacturing and shop drawings.
- Applying dimensions, tolerances, GD&T, and technical drawing standards.
- Reviewing and improving designs for DFM and manufacturability.
- Developing sheet metal and fabricated components where required.
- Making design revisions based on manufacturing and engineering requirements.
- Supporting product development from 3D CAD design through manufacturing documentation.
- Communicating remotely with the engineering team to understand requirements and deliver accurate design solutions.

Software: SOLIDWORKS, AutoCAD
Mechanical CAD Engineer Onsite FX Landscape · Freelance Aug 2021 – Jan 2024 2 yrs 5 mos New York, NY, USA Worked closely with FX Landscape, a company delivering landscaping and infrastructure projects across different locations, where I was responsible for the mechanical design and manufacturing documentation of custom landscape edging systems used around footpaths, trees, lakes, parks, and other landscaped areas.

My role involved developing 3D CAD designs with a strong focus on Design for Manufacturing (DFM), ensuring that each edging component could be efficiently fabricated, assembled, and installed on site. I also prepared precise fabrication-ready shop drawings containing dimensions, tolerances, bend details, and manufacturing specifications.

I enjoyed turning practical landscaping requirements into clean, manufacturable engineering solutions, carefully considering material usage, bending processes, fabrication constraints, installation requirements, and overall product performance. I worked closely with fabrication requirements to refine designs and make sure the final drawings could move smoothly from CAD to manufacturing and ultimately to successful site installation.

Key Responsibilities:

- 3D CAD design and development of custom landscape edging systems.
- DFM-focused design optimization for laser cutting, bending, and fabrication.
- Preparation of detailed fabrication and shop drawings.
- Development of flat patterns and manufacturing-ready DXF data.
- Applying practical tolerances, bend allowances, and fabrication considerations.
- Revising designs according to manufacturing and site requirements.
- Supporting the complete workflow from concept → 3D design → DFM → fabrication drawings → manufacturing.
Mecahnical Design Engineer Marks razmak · Part-time Mar 2017 – Feb 2020 2 yrs 11 mos Hayatabad, Peshawar, Pakistan Worked as a Mechanical Design Engineer supporting the design, development, and manufacturing of custom industrial and automotive components. My responsibilities included:

- Creating detailed 3D CAD models and assemblies using SOLIDWORKS.
- Preparing accurate 2D manufacturing and shop drawings with dimensions, tolerances, GD&T, and fabrication details.
- Designing and detailing sheet metal components, including bends, flat patterns, and fabrication-ready drawings.
- Developing components and assemblies for 3D printing and rapid prototyping, including design modifications for manufacturability.
- Preparing DXF files, cutting layouts, and fabrication drawings for laser cutting and sheet metal manufacturing.
