THE PROBLEM

Payment systems are often fragmented and overly complex, especially for businesses looking to expand into new markets. Managing multiple tools, integrating new payment methods, and scaling operations across regions created friction for both technical and non-technical users.

For engineers, the challenge was ensuring integrations worked smoothly across diverse payment infrastructures. For non-technical teams, the issue was navigating complicated workflows that felt unintuitive and slowed down daily operations. This tension made it difficult for companies to streamline customer journeys and innovate quickly.

THE SOLUTION

With Primer, my role was to design a platform that simplified complex payment journeys while remaining accessible to every type of user.

I focused on ensuring that every interaction from managing payments to integrating new tools felt seamless and intuitive. The emphasis was on balancing clarity, functionality, and aesthetics, so the system could scale with technical integrations while still being approachable for everyday users.

Through close collaboration with engineering, design, and compliance teams, I refined workflows, prototyped interfaces, and tested usability to confirm that the product worked equally well for technical specialists and general users. The goal was not just to streamline payment processes, but to create an experience where businesses could grow confidently without being slowed by system complexity.

THE CHALLENGES

Designing Primer presented several key challenges:

• Serving Multiple Audiences: Technical teams needed robust integration support, while non-technical users required an intuitive, approachable interface.

• Balancing Clarity with Power: The system had to remain feature-rich enough for specialists, yet simple enough for everyday use. Achieving this balance required refining even the smallest details.

• Cross-Functional Alignment: Because payments touch compliance, product, engineering, and partnerships, the design process demanded tight collaboration across multiple departments to ensure the platform addressed all needs.

• Scalability Across Markets: Primer had to support different payment regulations, currencies, and tools in a way that felt consistent globally, which added complexity to both the interface and the workflows.

RESULTS & OUTCOMES

The final product was a payment and commerce platform that gave businesses a clearer, more reliable way to scale their operations. Users described the experience as frictionless and intuitive, with payment processes that previously felt complicated now simplified into streamlined flows.

Usability testing confirmed that technical teams appreciated the platform’s robust integration support, while non-technical users valued the accessibility and clarity of the interface. The product successfully bridged two very different user groups, showing that thoughtful design could unite functionality and simplicity.

Perhaps the most rewarding outcome was seeing how Primer empowered businesses to innovate faster — making it easier for teams to expand into new markets without being held back by fragmented systems. For me, it reinforced the impact of design in solving problems that are not only technical, but also cultural and operational across a business.
