iPhone app programmer and web developer since 2010/04/27, previously worked in my small company as web designer+programmer.
With a dozen apps released I'm now reasonably experienced with iPhone development and all the things related to providing apps with data including responsive design websites, web apps, building company databases from scratch along with web and app interfaces, data migration, report design, email, charts and maps.
I now feel I can build anything in Objective-C and HTML5, CSS3, PHP, Javascript, XML, MySQL. In the world of changing frameworks - with a little help from my friends on Stack Exchange.
