E-Frinergy, an energy optimisation platform

Context
Identity & creation of an energy monitoring platform
Frinergy develops solutions for monitoring and optimising energy performance. For the e-Frinergy project, the challenge was to build a consistent visual identity and design the interfaces of a business application that makes energy data more readable and usable.
My work combined Brand Design and UX/UI design, with the goal of giving the product a recognisable identity and translating business needs into a clear, consistent and functional digital experience.
