What were the problems?

The previous system, initially built as an MVP on a ready-made e-commerce platform template, faced issues with bugs, responsive issues and inability to add new features. Therefore, a new custom-coded system was created, incorporating significant improvements in interface and usability.

The main point identified in a contextual interview I conducted before starting the project, was that the course preview video was important yet hidden.

After aligning with stakeholders, I designed the following interface for the purchase flow, as well as the entire back-office configuration.

Results

To validate the prototype, usability tests were conducted, and users received a SUS survey afterward, which resulted in a score of 90.

The biggest challenge during this process was recruiting users for the tests.

The main point observed after the tests was the difficulty in finding where to click to access the purchased course. For example: some users expected the purchased course to appear immediately upon logging in. After these tests, the course access screen was set to redirect users immediately after purchase.

Post-launch improvements were implemented, such as allowing purchases without registration, enabling the product to quickly reach its time-to-value.
