Hi, my name is Boris and I'm long term software developer, leading a team from Europe. I'm Canberra educated, but moved back in Europe and doing still some business with companies down under. With your specific requirements in mind, my team and I have handled a lot of applications, mostly for enterprises, but got few app store ones as well. I've been working in research and development for a while and we've very proficient with latest technologies, including cross platform/native development to cover Windows Phone, iOS, Android using Xamarin, HTML5/JS Web apps, high performance no-SQL databases (eg MongoDB) and been using Azure for over two years as backend. I would definitely like to hear more on your project and see how we can help. I can send you varios references, including companies from Australia. Cheers, Boris.
