By enhancing user experience through data-driven insights and employing best and latest design practices, I aim to boost traffic, elevate customer satisfaction, and refine your interface for continued evolution.

the process (specifically for usability test)

1. knowing the problem & forming hypothesis

2. define users tasks to prove or reject hypothesis in test

3. deciding what is best for testing

4. define demographics of users to bring in

5. organize and send invites, filter by typeform

6. prepare materials, prototypes and NDA
