RESEARCH

1. Wireframing & Iterations
I started with low-fidelity wireframes to map out the QuickPay portal’s flow, ensuring that users could enter their customer number, verify details, and pay seamlessly.
For the post-login dashboard, I tested layouts that emphasized invoices, analytics, and payment methods as primary actions.

2. UI/UX Considerations
I implemented a clean, modern UI inspired by Reclaim.ai and Slack’s onboarding.
Designed a responsive layout for mobile and desktop users.
Added a confirmation step to reduce accidental payments.

3. Collaboration with Engineers
Case Managers/Service Providers
Worked closely with software engineers to align UI components with development constraints.
Coordinated with backend developers to ensure that security best practices were followed in payment authentication and processing.
