How did you demonstrate to the customer what you have done?

For demonstrating the completed work to the customer, I use several approaches:

• Prototypes and mockups — I show interactive or static prototypes to visualize the interface and logic.
• Demonstration of the working product — if there is a ready functionality, I conduct a presentation showing the system's real operation.
• Video demo — I record short videos demonstrating key features.
• Step-by-step usage scenarios — I show how the user performs tasks within the system.

It is important to accompany the demonstration with explanations, answer questions, and record feedback for adjustments. This approach helps ensure that the product meets expectations and allows timely identification of possible shortcomings.
