Summary

Most of the drop-off sat in error states nobody had designed. Rebuilding recovery — not the happy path — is what moved the number.

About Project

Product Overview

A mobile-first payment flow where a failed card left users at a dead end with no way back into the transaction.

The Role

I owned the flow: instrumented the funnel, ran the session reviews, redesigned the states, and shipped it with the squad.

Problems & Challenges

Error copy that described a status code rather than a next step, and a keyboard that covered the field it belonged to on smaller devices.

Goals & Objectives

Keep every failure recoverable inside the flow, and make the form survive the range of devices actually in use.
