Piotr Knapczyk - Mobile app design and development

iOS and Android

Does your company need an app to allow mobile users to access your services? Or maybe you are a startup wanting to build Minimal Viable Product from your idea? I can offer comprehensive service, starting from design, user experience, through implementation and testing and finishing on App Store setup and management.

I am a contract mobile developer, with experience programing for iPhones and iPads (iOS) in both Swift and Objective-C, and Android in Java and Kotlin. I have experience in publishing apps into Apple's App Store and Google's PlayStore and handling design requirements from these stores.

Let's build your app!

Portfolio

Below you can see some of the projects executed from the idea to the final product. In total, all the apps were downloaded over 750k times.

App icon design

Every app needs an icon. We can provide high-quality app icons, designed and prepared for use for both Apple and android devices. The icons are created by a graphic designer with 20-years of experience in brand design, crafted to match your brand and the app's functionality.
