I am experienced ExpressionEngine developer, working with this CMS since 2009 (and in web development since 2003). My main specialization is creation of custom add-ons (but also do other EE-related stuff). I am author of 50+ add-ons (including some well-known, such as Social Login Pro, Social Update, Threaded Comments, Messaging). You can see a list of them by searching for my name at devot-ee.com.
