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!!
