High-Precision Mechanical Design & Prototyping by a Senior Engineer. Based in Berlin. Expert in Industrial Machines, MedTech, and 3D Printing Optimization.

I am a Senior Mechanical Engineer based in Berlin, Germany, with a passion for transforming complex conceptual requirements into robust, manufacturable products. With over a decade of experience in industrial machine design and medical device innovation, I provide a complete "Concept-to-Creation" service.

Why Choose My Expertise?
Unlike traditional CAD designers, I run a dedicated prototyping operation. I don't just deliver a digital file; I deliver a design that has been "vetted" by the physical laws of manufacturing.

Senior Engineering Pedigree: Extensive experience in high-level mechanical systems, MedTech (surgical accessories), and industrial automation.

DFM Expert: Deep knowledge of Design for Manufacturing—optimizing for injection molding, CNC machining, and sheet metal to reduce your production costs.

Rapid Iteration: Utilizing my in-house prototyping lab, I can test tolerances, fitment, and mechanical integrity in real-time.

Featured Services
Mechanical Design: 3D CAD modeling (SolidWorks, Inventor, AutoCAD) for industrial and medical applications.

3D Printing Optimization: Specialized in "remastering" models for 3D printing, ensuring structural wall thickness and perfect assembly tolerances.

FEA & Simulation: Structural and mechanical analysis to validate designs before production.

Technical Documentation: Production-ready 2D drawings, BOMs, and assembly manuals.

Work Terms

1. Milestone-Based Payments
For engineering projects, I prefer working with defined milestones to ensure transparency:

Milestone 1: Research & Conceptual Design (20%).

Milestone 2: Detailed 3D CAD Modeling & First Review (40%).

Milestone 3: Final File Delivery (STP, SLDPRT, STL) & Technical Drawings (40%).

Note: For prototyping, 100% of material and shipping costs are required upfront.

2. Software & Licensing
All designs are produced using fully licensed professional software (SolidWorks, AutoCAD, or Inventor). Clients receive full ownership of the final native files upon project completion and final payment.

3. Revisions & Scope Creep
Included Revisions: Each project includes [2 or 3] rounds of minor refinements based on the initial brief.

Out of Scope: Significant changes to the core functional requirements after the CAD phase has begun will be treated as a change order and quoted separately.

4. Prototyping & Physical Testing
As I operate an in-house lab in Berlin (Bambu Lab A1 and other equipment):

Verification: I can provide photo/video proof of "fit-tests" for interlocking parts.

Shipping: Physical prototypes can be shipped worldwide via DHL/FedEx from Berlin. Shipping fees and customs duties are the responsibility of the client.

5. Confidentiality & IP
I am happy to sign a Non-Disclosure Agreement (NDA) before discussing sensitive intellectual property. As a Senior Engineer, I maintain strict data security protocols for all client files.

6. Communication
I am based in Berlin (CET/CEST). I am available for video consultations via Zoom, Google Meet, or Guru/Upwork's built-in tools. I typically respond to messages within 2–4 hours during European business hours.

Strategic Tip for your "Hourly Rate"
As a Senior Engineer in Germany with a prototyping lab, do not price yourself too low.

CAD Design Only: $50–$80/hr.

Consultancy/MedTech DFM: $80–$120/hr.

Prototyping: Usually better as a Fixed Price per unit to cover filament, electricity, and machine m
