I use the Flutter framework to build high performance, maintainable mobile solutions, customized for your individual situation. In addition to the mobile app itself, I can build the required backend server for your business solution. I cover the whole project cycle, from requirements engineering over development, to delivery (basic UI/UX included, without advanced graphical design). Personally I work with Android only, although any iOS developer can easily support the app with little extra effort, using the same code base.
