    For twelve years, I work as an iOS Developer. During this time, I have completed many projects. More than half of my projects are client applications for servers. I understand how such applications are arranged. How to receive the data from a service using a REST API. I know how to parse a service response and display it in an app and create offline mode. I have experience with video and audio. I can combine video files, put sound on them, change this sound, add text or image to the resulting video. I worked with video and audio players and recorders. I worked with Maps. I can display places on this map, present custom callouts on it, and show routes from a user location to these places. I also can work with the CoreData framework. I know how to get data from a database on a thread and display it to a user without an interface freezing. In 2017 I decided to create some apps on my own. My friend is a radiologist, and he shared with me his idea about a medicine app. We have created this app and published it to AppStore. You can find it if you search for RadAnatomy and RadAnatomyLite. 50% of the proceeds I transfer to my friend. During the work on this app I put myself in the place of customers and gain the priceless experience how an idea is embodied to the app. I can use Photoshop and Sketch, and you do not need to slice images. Just provide me a file with a design. The rest I will do by myself. I pay attention to pixel-perfect and custom fonts because I respect designer work.
