When I joined the RADIUS project, I discovered a unique challenge: the original design files for the payment flows had been completely lost. This wasn't just about continuing someone else's work—I needed to reconstruct and improve critical banking functionality while the platform was being actively developed for a very specific audience: retirees managing pension accounts and retirement benefits. RADIUS serves users who need interfaces that prioritize clarity, security, and ease of use over complex functionality. These aren't typical banking users—they need access to pension information, retirement account management, benefit verification, and payment processing, but they're often less comfortable with digital interfaces and have very low tolerance for confusion or errors. For senior citizens, financial interfaces must immediately communicate security and reliability. Every design element needed to reinforce confidence rather than create uncertainty, requiring familiar patterns, clear confirmations, and obvious next steps throughout every interaction while supporting both English and Spanish-speaking retirees.

With no existing design files to reference, I had to understand intended payment functionality through conversations with the development team and product manager who managed client communication. My approach centered on reverse-engineering business logic while creating entirely new user flows optimized for senior user needs. Working within the existing platform structure, I designed payment flows that felt simple and reassuring while maintaining all necessary security protocols. Every step needed to clearly communicate what was happening and why, with confirmation screens, progress indicators, and error handling that would make senior users feel confident about financial decisions. The bilingual requirement wasn't just translation—financial terminology, cultural expectations around banking, and interface patterns all needed cultural adaptation. Spanish-speaking users often prefer more detailed confirmations and different information hierarchies, which I incorporated while maintaining functional consistency across both language versions.

Implementation focused on three critical areas: accessible payment flow reconstruction, bilingual financial interface design, and senior-optimized user experience. I redesigned payment processes to handle multiple validation steps, security checks, and confirmation processes while feeling simple and trustworthy for users making significant financial decisions. The payment flows needed to integrate seamlessly with existing platform components built by other team members, requiring careful coordination to ensure visual and functional consistency. I also contributed to the related PCS project, designing user validation flows and authentication screens that supported the overall retirement banking ecosystem. Cultural financial design considerations were crucial—different cultural backgrounds have different expectations for financial interfaces. I ensured security messaging, process flows, and confirmation patterns worked effectively in both languages while maintaining the trust-building approach essential for senior financial users.

The redesigned payment flows successfully launched as part of the RADIUS platform, enabling retirees to confidently manage their pension accounts and financial transactions. The accessible design approach and bilingual support made the platform usable for a diverse senior population across different cultural and linguistic backgrounds. Key deliverables included reconstructed payment flow systems, bilingual interface design, senior-accessible financial interfaces, and integrated authentication systems. The project demonstrated successful recovery and improvement of lost functionality while enhancing user experience for specialized senior financial services. This project taught me invaluable lessons about designing financial interfaces for users who need maximum clarity and minimum confusion—a very different approach from consumer banking apps prioritizing speed and efficiency. Understanding how to create truly accessible design for seniors required considering not just physical limitations but cognitive preferences, trust patterns, and technology comfort levels. Working with retirement banking showed me how interface design can either build or erode user confidence in critical financial decisions, becoming essential expertise for financial services design.
