Problem, constraints and approach
Klarna’s browser extension lets people pay later on almost any online store, including Macy’s, eBay, Walmart and Nike, with automatic coupons, cashback and one-time cards. Because it runs on other companies’ pages, a bug can put a partner at risk. eBay once gave Klarna a deadline: fix an extension bug, or end the partnership. I led the redesign, managed several critical features and found that bug’s root cause two days before the deadline.
What I built
- Led the redesign project.
- Managed the implementation of several critical features of the extension.
- Found the root cause of an extension bug affecting eBay two days before eBay’s fix-it-or-end-the-partnership deadline.
- Helped localize the extension into 18 languages.
Results
- Finding that root cause in time saved Klarna a significant amount of money.
