The challenge

Building upon the basic foundation, the project presented key challenges:

  • Responsiveness: Ensuring a consistent experience across multiple devices
  • Data Visualization: Simplifying complex energy-sector data with engaging charts and visuals
  • Performance: Optimizing load times and interactions for large datasets
  • Accessibility: Meeting WCAG guidelines while maintaining visual appeal

Our solution

The redesign process began with a thorough analysis of the existing basic user journeys and layout to identify key pain points and opportunities for improvement. Based on this analysis:

  • Refined user flows and re-architected the information structure
  • Implemented responsive design patterns for all device sizes
  • Created an intuitive data visualization system
  • Developed a comprehensive component library

Client testimonial

“I'm thrilled with the work Marius did for me. He turned my ideas into a great-looking and easy-to-use design. From the start, he understood what users would like and paid attention to the little details (which were very important to me). Marius isn't just a designer; he also solves problems and listens to feedback. He communicated well during the project and made changes when needed. I highly recommend Marius for UI/UX design. He did a fantastic job and after project completion, he is still available for suggestions and corrections. I am looking forward to working with them again. Thanks for making my project a success!”
