from Berlin, Germany.

Starting as a team leading UI/UX Engineer, I emphatically evolved into a Product Designer with a major interest and hunger for human-centered design. Excelling in intutitive user interfaces and experiences, and creating authentic connections between products, people and businesses.

Work

As a former engineer, I work very well deeply integrated in development teams, allowing me to ship efficiently and effectively.

In recent years I've been focused on the Energiewende at pioneering companies like EIGENSONNE, and 1Komma5°. My empathic user centric approach, has aided in increasing the consumer uptake of solar systems in Germany primarily and now throughout Europe.
