Project case study

  1. The challenge

    A lender needs a reliable way to monitor obligations across clients and avoid missing important dates.

  2. The approach

    Model clients with multiple debts, repayment deadlines, and scheduled reminders, with straightforward mobile navigation.

  3. My contribution

    Defined functional requirements, an initial data model, and usability guidelines.

Conceptual project: inclusion here does not mean the application has been released.
