I build flawless iPhone and Android apps for my clients and can start even with only your vague ideas or mock-ups. We can also discuss and/or enhance your app logic (if you have not completely figured that out yet). I work and communicate during your business hours and am also available to work on weekends and holidays if needed. My strength lies in backend development for mobile apps and to keep project quality, I write unit tests and also do maintenance after the app is published. If you are looking to create or update your app, no need to look any further... You are already in the right place :) Let's connect and get the ball rolling!
