I got my hands on iPhone SDK when it was first released in 2008. I was intrigued by the responsive touch interface, and since then I've written over 50+ apps and have worked with dozens of clients worldwide. In 2014 I started working with Android SDK as well. It was quite a change (and challenge..) coming from the iOS ecosystem but I embraced it and have become quite fond of it since then. Nowadays, it's very common for me to develop Android and iOS versions of apps alongside (although Natively). I've worked with clients from Silicon Valley to Singapore with experience in front and backend. I love developing MVPs (Minimum Viable Products) for my clients to test the market. If you have an idea, let's chat!!iPhone App Development

I am a full-stack developer, specializing in mobile (iOS/Android), Wordpress and Social Media Marketing. After years of working with overseas Developers to help me build my very own startup, I noticed that besides being able to find Devs at a fraction of the cost, the majority of Devs found did very unprofessional work, they were not organized, did not test and had weak code/design skills. So where do bootstrapped startups go to develop their MVP's? I decided to be part of the solution. I now work with an amazing team of highly skilled developers/designers that understand the startup culture and specialize in fitting within a bootstrapped budget. I have experience working with startups; I’ve attended Founders Space, one of the top Incubators in the country based in San Francisco. Myself including our team have a wealth of knowledge when it comes to building a startup from an idea to a reality.iPhone App Development

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.iPhone App Development
