UI/UX Designer

This product involved the development of an entirely new web-based platform for a debt collection company to use with their registered debtors to manage debt cases. The aim was to create a user-friendly interface for handling debtor information, case history, and communication. This new product was designed to improve the debt collection process and significantly enhance the overall user experience.
The project spanned 6 months, moving swiftly through research, design, development, testing, and deployment. With iterative feedback and agile updates, we adapted to stakeholder input and evolving needs throughout the process.
I led the end-to-end UX and UI design process, from wireframes and prototypes to UI development and developer handoff. I collaborated closely with Business Analysts, Product Owners, and developers, gathering feedback and iterating designs through user testing to ensure the product met both user needs and business goals.
The project was necessary to address several key inefficiencies in the debt collection process. The business needed a streamlined solution to manage debtor information and debt cases more effectively. Specifically,
When I started designing this web application, we identified several problems in the existing debt collection process. Through discussion sessions with our Business Analyst (BA), stakeholders, and the company’s domain experts, we reviewed the current workflows to understand the main pain points.
“To address these issues, we designed a self-service debtor portal with a smart, self-guided action flow that guides users through case actions, achieving zero case handler engagement, along with a design system supporting brand variations and prioritizing clarity, accessibility, and scalability. Additionally, we implemented a mobile-first responsive design to ensure seamless performance across all devices.”
Collaborated with the Business Analyst, Product Owner, and domain experts, conducted current-state mapping, and analysed similar financial self-service platforms to understand what users like, what they want, pain points, and key challenges for both portal users and case handlers, resulting in insights and design patterns to guide self-service and case management features.
Mapped end-to-end user journeys, task flows, and information architecture for key actions such as viewing case details, updating information, and making payments to create a simple, guided self-service experience that reduces user confusion and dependency on staff, resulting in clear flows that prioritize primary actions and provide a strong foundation for prototyping.
Developed wireframes and interactive prototypes to simulate key user flows, conducted usability tests to validate design solutions, and gathered feedback from users and stakeholders to refine and improve the designs.
Engaged continuously with the Business Analyst, developers, and QA through meetings and daily stand-ups to align on business goals and technical feasibility, ensuring a balance between user needs and business objectives.
Developed a reusable design system with responsive layouts and UI components, implemented using HTML, SCSS, Bootstrap, and Angular. SVG icons were used to ensure scalable, high-quality visuals and consistent styling across screen sizes, resulting in a cohesive, brand-aligned interface and more efficient development.
To enhance self-service, the action menu was moved from the payment page to the main navigation, giving users easier access to key actions and enabling independent task completion. In hindsight, testing this change earlier could have revealed additional opportunities to simplify navigation and further improve usability.
Using these insights, we developed a solution that resolved key challenges and established a foundation for a more efficient user experience and improved business performance.
