      Where I contributed

       

      01

      Recently, I worked as a Senior Product Designer in a property technology company that enables selling and purchasing of real estate. I carried out design and research projects for business-to-consumer products and internal sales and administrative tools. The biggest challenge was that I was the only Product Designer.

      02

      Before that, I worked for 3 years in the fintech realm on open banking consumer-facing products. I was responsible for end-to-end product design and for the usability testing efforts and became UX Research Lead in my last year there.

      03

      As a freelancer, I had the chance to shape the branding and UI of the start up Grow My Tree that helps to reduce CO2 emissions through tree planting projects.

      A little bit about me

      My methodology

      I build products and features based on research and data. The logical approach evokes positive emotions on the users' side.

      Through feedback I strive to take business requirements, stakeholder needs and technical constraints into account. This is how I make businesses' products appear valuable and clear in their communication.

      Where I contributed

        01

        Senior UI Designer in renewable energy startup

        Since Oct 2023 I worked in the green tech aiming to simplify the clean energy transition. I relaunched the heatpump and solar comparison enabling homeowners to request and compare offers from multiple installers. Not only did I learn about the user base of homeowners, but designed B2B solutions enabling cooperation partners to manage provided leads.
        02

        Senior Product Designer at a PropTech

        Recently, I worked as the sole Senior Product Designer in a property technology company contributing to two squads. I carried out design and research projects for business-to-consumer products and internal sales and administrative tools.

        03

        UX / UI Designer and Research Lead in a FinTech

        Before that, I worked for 3 years in the fintech realm on open banking consumer-facing products. I was responsible for end-to-end product design and for the usability testing efforts and became UX Research Lead in my last year there.

        04

        Freelance projects

        Since 2018 I am engaged in freelance projects. I delivered dashboards for BMW Group IT and I had the chance to shape the branding and UI of the start up Grow My Tree that helps to reduce CO2 emissions through planting trees. I also created landing pages for businesses such as a pharmacy and an arborist business and implemented them in a content management system.

        05

        Academic background in design and business

        I have a Bachelor in Business Administration and in Media and Communication Design. I used every grant possible and was fortunate enough to spend practical semesters in Hamburg and Munich and exchange semesters in Nice and Bangkok.

        06

        Volunteering

        Apart from a voluntary social year in a workshop for people with special needs, I recently spent 1,5 months volunteering on two farm communities. I have learned about nature, market gardening and agriculture when I prepared patches, planted seedlings and weeded and mulched in the greenhouse together with five other volunteers.

        Wishlist for my next role

        Continue adding value to the planet or society

        01

        I identify to a great extent through my job. I need to know that every minute of my work time I contribute to a good cause.

        Emphasis on design work

        02

        Since January I had the chance to take on Product Management responsibilities alongside my UX design role. While I profit from the insights into product strategy and developer handover, I want to cultivate a strong product mindset in a UX design role. I especially value research-driven decision making to create joyful and meaningful user experiences.

        Work in a small or medium sized company

        03

        I thrive in smaller teams with short and direct communication channels. I value a collaborative environment where everyone works closely together and fast iteration and deployment cycles. This is how ideas turn into tangible results quickly.
