“The Legal Bible of Freelance Mechanical Design” is much more than a book.
It is:
→ a guide to securing your activity
→ protection for your know-how
→ a strategy to work confidently with your clients
Because a good freelancer should not only know how to design.
They must also know how to protect their work.
