The case
Following a period of hyper-growth, global digital payment provider PPRO was pushed to a fragmented and inconsistent UX/UI. This lack of consistency and cohesion hampered the company's efficiency and brand recognition, as the following screenshots illustrate.



1 - Led the modernization and unification of PPRO's digital interfaces suite and paper-based processes as part of a high-impact, five-member team:
- Cristian Hernandez (Senior Software Engineer)
- Joharvi Garcia (Senior Product Designer)
- Saul Hernandez (Software Architect)
- Stuart Wilson (Senior Product Manager)
- Oleksandra Solodska (Senior Frontend Developer).
2- Establish a new framework for measuring the success and performance of internal and external products based on user interface interactions to take data-driven decisions at strategic plannings and crucial moments.

To grasp the extent of frontend quality and backend informational architecture inconsistencies, I conducted workshops with engineering, product, and business teams. This allowed me to gather diverse insights, understand processes, pinpoint user pain points, and identify challenges and business opportunities.

I transformed initial research into various designs, prototypes, and internal tests, iterating from low to high fidelity for components, pages, and layouts. This iterative process ensured the final solution unified business needs, customer requirements, and team capabilities into a cohesive and feasible outcome.
The image below illustrates the design-to-development process: on the left is the Figma wireframe of a table component, while the right shows its local implementation (on port 3000) using React.js, Typescript, Tailwind, and MUI.

The final table, data table, and over 100 components were added to the global design system catalog and inventory. They were then distributed via the global component library and adopted across the Dashboard and Back Office platform services.

Below is an example of the new components implemented consistently across multiple interfaces and new products within the Customer Dashboard and Employees Back Office.
