Mobitafel
Mobile app for sustainable everyday mobility
iOS and Android shipped in 10 weeks with cross-platform CO2 tracking.
End-to-end design and development.
This case shows that I can build beyond SaaS dashboards: mobile flows with clear everyday UX and an existing backend landscape.
The German Environmental Foundation wanted to make sustainable mobility more visible and easier to use.
The app had to connect rides, onboarding and impact without losing users in sustainability logic or registration friction.
React Native with Expo, phone authentication via Twilio, integration with a WordPress backend and a clear flow for rides and CO2 impact.
What this case proves
Mobile UX must explain fast
On small screens, every step matters. The flow had to guide users and remain quick.
Use existing infrastructure pragmatically
The WordPress backend was integrated instead of forcing the organization into an unnecessary platform change.
Impact needs daily usability
Sustainability features work when they fit into normal usage instead of sitting aside from it.
The mobile entry focuses on the action, not on explaining the entire sustainability model.
“During our time together we mainly worked on one big project, which was handled by a team of up to 6 developers. Lukas worked on the Frontend and covered all corresponding areas. He was able to adapt quickly to new challenges and master them quickly. He always kept an overview of upcoming tasks and was able to prioritize very well. He also quickly got used to AWS and was able to handle it accordingly. Overall, Lukas was a pleasure to work with and I would recommend him to anyone in the future.”
