We need a cross-platform mobile UI library created using Xamarin with native iOS and Android libraries (not Xamarin Forms). This library will be used in multiple applications by our existing internal developers who will be writing the business logic. The library will contain controls like cards, toolbars, tree controls, drag & drop views, etc. Some controls can use existing libraries while others will be highly customized. The controls must be highly polished, enterprise grade quality, and they must be entirely self contained in an API easy to use by our business logic developers.
You MUST have extensive experience with Xamarin and you MUST provide links to a portfolio of commercial apps showcasing polished UI controls you have written. You MUST be able to provide daily communication on the project with excellent communication skills and preferably close in timezone.
*** No Automated Proposals ***
Please read the description carefully and only reply with RELEVANT experience and portfolio links. Thanks.
