Request for Patent Drawings in AutoCAD + NDA Agreement

I am looking for a Russian-speaking freelancer who can help me prepare technical patent drawings in AutoCAD for a robot that cleans solar panels.

The project includes:
Creating detailed 2D or 3D technical illustrations suitable for patent submission (top view, side view, isometric if needed)
Understanding of basic engineering design or robotics is a plus

Clear and precise visual communication of mechanical elements

Requirements:
Fluency in Russian
Experience in AutoCAD and technical/patent drawings
Willingness to sign an NDA (Non-Disclosure Agreement) before starting
Deliver source files and high-resolution exports

If this sounds like something you can help with, please let me know:
1. Do you have experience with patent-style drawings?
2. Are you comfortable working under NDA?
3. Can you communicate in Russian?

Thank you!
I look forward to working with you.
