Every completed step stays in view.
Before, what you'd entered disappeared and, to change it, you had to go back step by step. Now it stays at the top, with “Edit”.

The checkout worked, but it didn't always tell the truth.
I redesigned how it looks and how it flows.
And I led its AI-assisted build. Payments, shipping and guest checkout had already been built by a teammate.
In production in 9 days.
Five parts, each delivered separately.
Tools: Claude, interactive HTML prototypes, Linear and GitHub.
Before
After
These are test screenshots, with the same data on both sides.
Before, what you'd entered disappeared and, to change it, you had to go back step by step. Now it stays at the top, with “Edit”.

Before, it could say “ARS 0.00” even when shipping wasn't in the total. Now, “To be determined” until it's chosen, and “Free” only when it really costs nothing.


Before, it said “Purchase Successful!” with any method, even with an unconfirmed transfer. Now, one title per situation, and “Purchase successful” only when the payment is approved.


Before, the button sat at the end, below the products. Now it's in a sticky, full-width bar, with the collapsed summary that opens when you tap it.


Each one was reviewed separately and merged following the team's conventions for branches, titles and descriptions. When a teammate's code changed midway, I kept their changes and listed them in the PR.
When each part was built
It was the night it launched. All five depended on real data, which only existed in production.
One small fix per problem, each with a test that failed before and passed after.
