Month 1: Discovery and Design

Collaborated with Fiserv and client stakeholders to assess operational bottlenecks and define technical requirements. Documented specifications for Single Sign-On (SSO) integration leveraging Fiserv’s Communicator Open framework. Designed a slide-out user interface to streamline access to contextual cardholder data.

Month 2: Development

Implemented the SSO module to enable secure access to Client Central. Developed the slide-out interface and real-time data mapping layers, engineered for compatibility with DNA’s .NET-based infrastructure. Introduced forward-compatible mechanisms to accommodate future DNA version upgrades and .NET architecture changes.

Month 3: Testing and Refinement

Conducted comprehensive unit testing to validate SSO authentication flows and interface responsiveness. Verified data retrieval accuracy and resolved identified bugs. Deployed the solution in a controlled test environment across select pilot institutions. Captured feedback on usability and performance to fine-tune the interface.

Months 3–4: Deployment and Support

Released the production-ready application via Fiserv’s AppMarket within a 3–4 month window. Delivered end-user training and institutional onboarding support.
Established protocols for version-aware maintenance of .NET-based components to ensure ongoing alignment with DNA platform updates.

The Client Central Integration DNAapp simplified access to Fiserv Card Services, enhancing efficiency and customer service. By integrating seamlessly with DNA, it reduced operational friction and empowered financial institutions to deliver faster, more reliable services.
