    Holi Jun 2022 - Sep 2024
    holi is the digital space where people and organizations come together to act for common good. It strives to be the launchpad for social and ecological activism by integrating existing tools and developing own.Being responsible for all core features of the ecosystem since the early days (as I was employee #4), I shaped the product from discovery and user research over all lifecycle stages to shipping the very first version of our app this summer. Whilst growing the team from 1 perm dev and a freelance designer to currently 7 developers and 2 designers, I – once again – learned a lot how to build successful teams and drive them to velocity.

  • Sinnerschrader Swipe Gmbh
    Product Manager
    Sinnerschrader Swipe Gmbh Jan 2018 - Jun 2019
    Hamburg Und Umgebung, Deutschland
    While working at Swipe I had the chance to work on various app projects for different clients.For roughly a year I worked for Audi and led the team of 8-10 designers for Audi’s main digital touchpoint. We fully redesigned the app in time, scope and budget and could increase app downloads by 36% and app rating up to 4.2. Afterwards, I led a team creating the global intro landing page (40 markets) of Audi’s first full EV – the eTron. It had over 25M page visits within the first quarter after launch.Then I moved on to shape hvv switch which combines the Hamburg local transport ticketing with new age mobility services. In this project I led a team of 8 developers and 2 designers. We were able to develop and implement a modular design system which gives room to grow when new mobility services are added but remains the simplicity and joy of use. Furthermore, we delivered full app design in time, scope and budget.
