About

I am a Senior Mechanical Product Design Engineer and Siemens NX CAD Consultant with 12+ years of professional experience in mechanical product development, 3D CAD design, automotive engineering, engineering change management and technical project coordination.

My primary expertise is Siemens NX, with extensive hands-on experience in both solid and surface modelling. I have worked on complex product development programs where accuracy, design intent, packaging, manufacturability, quality and engineering requirements are critical.

I can support clients with complete or partial product development activities, from interpreting engineering requirements and reference data through 3D modelling, design modification, CAD review, design validation and engineering documentation.

KEY CAD & DESIGN EXPERTISE

• Siemens NX 3D CAD modelling
• NX solid modelling
• NX surface modelling
• Parametric modelling
• Feature-based modelling
• Complex geometry development
• Product design and development
• CAD model modification and optimization
• Existing CAD model review and correction
• Feature-tree and design-intent review
• Design feasibility assessment
• Packaging and interface checks
• Engineering design reviews
• 2D drawing interpretation and review
• GD&T awareness and application
• Design for Manufacturing (DFM)
• Design for Assembly (DFA)
• Manufacturability reviews
• Design optimization and VAVE support
• Engineering change implementation

AUTOMOTIVE & PLASTIC PRODUCT DESIGN

I have extensive experience in automotive product development, particularly interior and exterior components and plastic parts. My experience includes working with complex styling surfaces, packaging constraints, interfaces, mounting strategies and manufacturing considerations.

Areas of experience include:

• Automotive interior components
• Automotive exterior components
• Instrument panel and related components
• Center console and console components
• Fascia and bumper components
• Grille and grille-related components
• Fenders and claddings
• Exterior trims
• Interior trims
• Plastic housings and covers
• Master sections
• B-surface development
• Parting and manufacturing considerations
• Mounting and attachment concepts
• Component interfaces
• Packaging and clearance checks
• Design validation and issue resolution

I understand the complete engineering thought process behind a CAD model and do not treat CAD modelling as only a drawing or modelling activity. I focus on design intent, functionality, interfaces, manufacturability, quality and ease of future modification.

CAD MODEL REVIEW & IMPROVEMENT

I can also support clients who already have CAD models but need an experienced engineer to review or improve them.

Services can include:

• Reviewing existing Siemens NX models
• Checking feature-tree structure and design intent
• Identifying modelling issues
• Improving model editability
• Reviewing complex or poorly structured models
• Rebuilding or modifying geometry where required
• Checking interfaces and clearances
• Identifying potential manufacturability concerns
• Reviewing CAD data before downstream engineering/manufacturing activities

This can be particularly useful for companies that need an experienced CAD engineer to independently review work completed by another designer or engineering team.

CAD DATA & TEAMCENTER EXPERIENCE

I also have extensive experience with Siemens Teamcenter and engineering data management. My experience includes:

• Part and data-set management
• Revision management
• Engineering release processes
• Workflows
• Engineering data organization
• CAD data management
• Product structure awareness
• Release and change processes
• User guidance and training

I can support organizations that require practical guidance for engineers working with NX and Teamcenter.

ENGINEERING CHANGE & PRODUCT DEVELOPMENT

I have significant experience supporting engineering changes and product development activities in an OEM engineering environment.

I can assist with:

• Engineering change implementation
• Design modifications
• Change impact assessment
• Release preparation
• CAD validation
• Design issue resolution
• Engineering documentation
• Coordination between design and engineering teams
• Design review and technical clarification

REMOTE CONSULTING & FREELANCE SUPPORT

I am comfortable working with remote teams and can independently handle assigned engineering tasks with clear requirements and deliverables.

I am open to both short-term and long-term freelance/consulting assignments, including hourly work, project-based work and ongoing remote engineering support.

I can support clients in areas such as:

• Siemens NX CAD modelling
• Mechanical product design
• Automotive CAD design
• Plastic component design
• Industrial product design
• CAD model modification
• CAD model review
• Design validation
• DFM/DFA review
• GD&T and drawing review
• Engineering documentation
• CAD data preparation
• Teamcenter support
