Finastra Fusion is a modern, API-driven core banking platform used by financial institutions to power critical customer and operational workflows. This case study explores how I led the prototyping and experience design of a Fusion-based banking solution—translating complex core banking capabilities into clear, efficient, and trustworthy user experiences for both customers and bank employees. The work focused on validating real-world banking workflows, reducing operational friction, and demonstrating how thoughtful UX can unlock the full value of a configurable core banking platform.

Core banking platforms like Finastra Fusion form the backbone of modern financial institutions, yet their complexity often limits usability and adoption. In this case study, I detail how I prototyped and designed a user-first banking experience on top of Finastra Fusion—bridging business goals, regulatory constraints, and technical realities. The project showcases how experience-led design can modernize core banking interactions, accelerate decision-making, and improve confidence across customer-facing and back-office journeys.


Banks can offer high levels of personalization and lifestyle banking capabilities
Finastra has been serving mainly from urban areas of cities not the rural areas banking needs. The personas and needs of the rural American banking were too different than urban.
The purpose is to help, enable and connect rural world to the digital banking.


Information pertaining to each user type helped us elevate the ideation of the product and created low fidelity wireframes to ideate fast with business stake holders
Defined prototyping goals, scope and success metrics with stakeholders (product, engineering, operations, compliance).
Mapped current-state Fusion workflows and prioritized high-impact use cases to prototype (account opening, inbound payments, dispute resolution, loan servicing).
Ran co-design workshops with business SMEs to translate Fusion config and data model constraints into UX patterns.
Designed and built interactive prototypes (low → high fidelity) to validate flow logic, error states, and micro-interactions tied to backend behaviors.


To validate the effectiveness of the proposed experience, I led a series of role-play–based usability testing sessions with representative users, including bank operations staff, relationship managers, and customer-facing personnel. Given the complexity of core banking workflows and limited access to live systems, role-play testing enabled us to realistically simulate day-to-day banking scenarios while interacting with the high-fidelity prototype built on Finastra Fusion capabilities.
Participants were guided through real-world tasks—such as account onboarding, payment processing, exception handling, and servicing actions—while assuming their actual job roles. This approach helped uncover not only usability issues, but also decision-making friction, handoff gaps, and compliance-related concerns that typically surface only in production environments.
The sessions focused on evaluating:
Error handling and recovery flows under simulated failure conditions
Insights from the role-play sessions directly informed iterative design improvements, including simplified workflows, clearer system states, and more contextual guidance for users. The testing confirmed that the prototype significantly reduced cognitive load, improved task confidence, and aligned more closely with how banking teams operate in real scenarios.
Overall, role-play usability testing proved critical in validating both usability and operational feasibility, ensuring the solution was not only intuitive but also practical, compliant, and ready for phased implementation on the Finastra Fusion platform.
