Experienced Flutter Developer (Toni Kroos, Ex About You, Union Investment Group, etc.)

2/2023 – 8/2023

Consulting a well funded Startup with the architectural decisions of their Flutter App, introducing many new approaches resulting in better layer separation, testability, fewer bugs as well as faster development speed.
I also consulted on the setup and deployment of their backend, the database integration, optimization of some queries to reduce latency and eventually helping migrate to a more cost efficient solution. Furthermore I functioned as a Quality Gate for outsourcing some development to non-european countries.
