Vopak, a global leader in energy storage and logistics, faced significant technical debt across its internal tools. The absence of a defined style guide and consistent UI component structure led to fragmented interfaces, duplicated logic, and maintenance challenges for multiple development teams.
To address this, Vopak embarked on a multi-year initiative to build a solid and scalable UI architecture that ensured visual and functional consistency across all internal applications while improving developer productivity and reducing maintenance effort.
During this phase, the focus was on addressing one of Vopak’s key challenges: the absence of a unified style guide and increasing technical debt across UI components.
Hi Interactive collaborated closely with Vopak’s development teams to establish a single source of truth, providing a consistent, scalable, and maintainable foundation for their internal tools.
A new UI architecture was introduced, supported by 186 reusable components to standardize development and remove redundancy. All components followed strict validation and controlled release processes, ensuring quality and reliability across environments.
The system enables parallel team collaboration, allowing components to be updated and integrated without disrupting existing applications. Performance was prioritized to ensure complex, data-heavy tools run efficiently across business-critical systems.
Throughout this three-year collaboration, we acted as a technical and strategic partner, helping Vopak’s teams reduce UI-related errors, improve performance, and modernize their internal development process.
This long-term partnership ensured continuity, alignment, and progressive improvement across multiple internal products. By combining hands-on delivery with strategic guidance, we helped establish stronger standards and a more resilient development framework.
A joint team of four developers worked in agile sprints with shared goals, ensuring close alignment between experience, design, and front-end development. Ongoing documentation, workshops, and live previews enabled Vopak’s teams to adopt best practices independently.
Built-in alerts prevented incorrect component usage, significantly reducing recurring issues and support requests. Legacy components were gradually deprecated through clear versioning and release communication, ensuring smooth adoption across product teams.
The Vopak Ul Framework became a cornerstone for efficient, standardized front-end development across multiple teams and projects. By consolidating legacy Ul patterns into a single, well-structured system, Vopak significantly reduced inconsistencies and improved development speed.
The collaboration between Hi Interactive and Vopak not only eliminated a substantial amount of technical debt but also created a sustainable, future-ready foundation for continued evolution.
This effort resulted in measurable gains in speed, reliability, and usability, allowing development teams to focus on innovation rather than maintenance.
