Senior Product Designer

Designing complex products that work for users, and survive contact with the business.

Melanie Bello
01 / Premise

From low conversion to real adoption, using data, research and product thinking to fix what actually matters.

02 / About

Where business logic meets user behavior.

7+ years across fintech, banking, and B2B. Currently Senior Product Designer at Interbanking, a B2B payments platform in Argentina. Previously with Tenpo, BBVA, Amazon's Climate Pledge, and Banco Supervielle.

In financial products, designing for the user isn't enough. You have to design with the business model, the operational constraints, and the risk logic in the same breath. I work end-to-end on credit, insurance, payments, and fraud flows. The constraints aren't obstacles. They're part of the brief.

The pieces that didn't sell
