Overview
What started as a Swedish portal became part of something much bigger. I helped shape the foundation that evolved into One Nexi Developer Portal, bringing together documentation across the Nexi and Nets network into a single entry point for a large European payments ecosystem.
The challenge
This was not a docs refresh. It was a consolidation effort across scattered portals, overlapping products, legacy setups, and new services being onboarded at the same time. The portal had to work for developers, but also for support, product discovery, and future business relationships. It needed to explain a growing ecosystem, not just host pages.
My role
I led the design work across research, interviews, surveys, Hotjar analysis, information architecture, wireframes, prototypes, UI, and content structure. I worked closely with developers, product owners, tech writers, support, and other stakeholders to identify gaps, dead ends, and friction points, then turn that into a clearer, more usable experience.
Key decisions
Turn the portal into a real front door.
The portal needed to do more than serve existing technical users. It had to present the ecosystem clearly, help people understand the offer, and make the next step obvious.
Design for complexity, not just content.
The real problem was fragmentation. I focused on structure, hierarchy, and product relationships so the platform could feel coherent even as it grew.
Support troubleshooting as much as onboarding.
This was not only about getting started. It was also about making it easier to understand what was live, what had failed, and where to go next.
Build something that could absorb growth.
New products were being onboarded continuously. The experience had to scale without collapsing into the same mess it was trying to replace.
Outcome
The result was a stronger and much more strategic documentation experience. Not just clearer for developers, but more useful for support, more credible externally, and better suited to a group operating across more than 25 countries. It became a much stronger face of the ecosystem, not just a place to store docs.
