Enterprise Product & Rebrand · Sole Designer
Making a legacy platform simple, accessible and built to scale.
Transforming a legacy EDI platform into a scalable, accessible SaaS product.

Outcome
40%+ faster processes
Standard
WCAG 2.1 AA
Setting the Scene
When I joined NetEDI, their internal platform NetIX was critical to day-to-day operations but had outgrown its foundations. Built in Microsoft Silverlight, it was outdated, visually inconsistent, and difficult to navigate.
As the sole designer, I was responsible for bringing clarity, structure and usability to a deeply technical enterprise product used by clients including DPD, Radley, Tangle Teezer and NHS Supply Chain.
The goal was to modernise the interface and improve usability for both technical and non-technical users, without disrupting hundreds of live customer integrations.

NetIX interface, before redesign
Part One
Modernising NetIX
Problem
The legacy platform was functional but inefficient and difficult to use. It looked and behaved like a system designed for engineers, not for people managing business operations.
- · Complex terminology and poor hierarchy
- · Minimal validation, feedback or error handling
- · Inconsistent layouts and navigation
- · No scalability for tablet or desktop responsiveness
Process
I began by mapping every workflow, from document processing to profile setup and error resolution. I interviewed support and engineering teams to understand friction points and identify which workarounds had become “standard practice.”
From there, I designed new structures for:
- · Dashboards showing live order and invoice volumes at a glance
- · Editor and process screens simplified for data entry and validation
- · Document overviews with clear state, buyer and seller visibility
- · Reusable tables with filtering and inline actions
The redesign prioritised hierarchy, whitespace and error prevention, resulting in a modular system that could scale across devices and screen sizes.

Outcome
The new NetIX interface replaced Silverlight with a modern, modular design system.
It reduced the time to create or update a process by over 40 percent, and significantly decreased support requests.
“Looks 100 times better and is a lot easier to use.”
“A better platform from a technology and compatibility point of view.”
“More user-friendly. Looks very good, easy on the eye.”
Part Two
Post-Acquisition Rebrand
Context
In late 2019, NetEDI was acquired by Cegedim Group, a French SaaS provider headquartered in Boulogne-Billancourt, Paris. NetIX became part of Cegedim’s wider ecosystem, and I was asked to align the product with their Sy platform branding.
Challenges
- · Redesigning a product that had just launched
- · Balancing brand consistency with accessibility and usability
- · Raising WCAG 2.1 AA compliance concerns around the parent company’s colour palette
- · Coordinating implementation between UK and French engineering teams
- · Introducing the first structured design tokens and variables into a legacy CSS codebase
Process
I reviewed Cegedim’s brand library, compared colour and typography systems, and ran accessibility testing across all proposed palettes. Where contrast ratios failed, I documented issues and presented compliant alternatives to both design and engineering teams.
To manage scope, I standardised UI components and layouts to form the foundation of a shared design system, mapping tokens between Figma and CSS. I planned updates in Jira, sketched rebranded dashboards, and validated designs through prototypes incorporating accessibility feedback before any implementation began.
Collaboration with Cegedim’s product and engineering teams in Paris was critical. I travelled to Boulogne-Billancourt to work on-site with stakeholders and developers, reviewing accessibility adjustments, aligning with the French marketing team, and presenting progress to executive sponsors. This face-to-face collaboration accelerated decision-making and ensured design quality held up across both product ecosystems.

Rebrand: before and after Cegedim alignment
Outcome
The rebrand delivered a unified, accessible interface that preserved NetIX’s usability while aligning it with Cegedim’s broader SaaS suite.
- · Introduced consistent visual hierarchy and colour usage
- · Established WCAG-compliant colour tokens and typography scales
- · Improved user trust and engagement post-acquisition
- · Created the groundwork for a scalable design system across multiple Cegedim products
Reflection
This project marked a turning point in my career: the first time I had full ownership of an enterprise SaaS product from research through to system-level design.
Collaborating closely with Cegedim in Paris, including working on-site in Boulogne-Billancourt, gave me first-hand experience of how international product teams align brand, accessibility and technical delivery.
NetIX evolved from a legacy desktop app into a scalable, compliant platform that customers described as faster, smarter and easier to use. The work established a design and technical foundation for future integrations, letting the company expand partner connectivity without re-engineering setup logic each time. It also strengthened my ability to lead design work across teams, languages and cultures, experience that still shapes how I approach complex, system-wide projects today.
