Context
The fleet management platform was used by a variety of clients, from municipal fleets to airports. Over time, new features were added such as vehicle reservation, telemetry monitoring, and invoicing. Each client used a different mix of these features, which were integrated in a fixed way.

Industry Context
SaaS for industrial fleet operations
Challenge
This setup limited scalability and flexibility, both for the product and for future business models. At the same time, the platform allowed clients to select their own theme colors, which often resulted in inconsistent, visually disharmonious, and sometimes inaccessible UIs.
The challenge was to transform the platform into a modular, scalable SaaS product with a unified design language — one that could adapt to diverse clients while maintaining usability and visual consistency.

Approach
Redesign & Design System
The platform was restructured with a modular architecture, enabling features to be offered and sold as independent add-ons (e.g., invoicing, telemetry, winter service).
I created a design system with standardized typography, color, and components to ensure consistency across web and mobile. To preserve brand identity without compromising usability, unlimited color customization was replaced by logo integration — maintaining client recognition while keeping the interface cohesive.
Industrial Features
Automated Invoicing
Designed workflows to automate invoicing for fleet operations in municipal and canton contexts, reducing manual errors and administrative effort.
Winter Service Operations (Airport Use Case)
Developed a real-time map interface for monitoring snowplows and de-icers during airport winter operations. Conducted contextual inquiries directly in the vehicles to understand environmental and usability constraints.
Telemetry Dashboards
Translated raw vehicle telemetry into digestible dashboards, supporting quick decision-making by fleet managers.
Mobile Driver App
Designed a companion app for drivers, enabling vehicle booking, keyless entry, and incident reporting. The interface focused on simplicity and accountability, minimizing friction while ensuring reliable reporting and integration with the fleet platform.
