Services
We can do many things most expertly:
Mobile platforms
Android, iOS, KMP, Flutter, React Native, Xamarin, C++, … we’ll help you choose the best approach for your project, plan it, architect it and build it.
DevOps
Your apps will need a backend, an API, a caching strategy, a continuous integration process… we’ve got you covered.
From scratch
We have built lots of apps from the ground up. We know what we are doing and we’ll be happy to do it again with you.
Firefighting
Rebuilding a “bad” app from scratch might not be the best option for you. We are experts fixing the weirdest bugs (you wouldn’t believe) and getting you into a better position.
Code & architecture review
Not sure about what exactly the state of you mobile apps’ code or architecture is? We can give you an expert report and help you plan improvements, scaling up/down, optimise costs…
