stromee is a green energy provider based in Berlin. stromee offers green electricity, green natural gas, and heating electricity. Instead of supplying electricity from an anonymous source, stromee operates as a marketplace: Customers select their electricity directly from independent, mostly smaller producers—such as wind, solar, or biogas facilities—located throughout Germany. Contracts, advance payments, and meter readings are handled entirely digitally via the app and web app. In addition to residential customers, stromee also serves small and medium-sized businesses with its own commercial rate plan.

I’m responsible for everything related to design at stromee—from the website and app to the portals, invoices, PDFs, and marketing. I quickly bring new ideas to life as mockups, creating a foundation for decision-making. I always work in close collaboration with the development team, from the initial idea through to implementation. As a result, I often serve as a liaison between management and development.

​

Over time, I’ve taken on more and more areas of responsibility, even beyond traditional design: I’ve helped shape processes and, for example, developed the implementation of the CO₂ Cost Allocation Act—including an Excel tool that allows us to generate the necessary PDFs for customers.
