I've been programming professionally for the past 9 years. Currently, my speciality is iOS development (though I still dwell in the backend world from time to time using Node or Python). I've been using Swift since it was first released in 2014 and the app that I've worked on for the past 3 years (Hole19) has been consistently rated 5 stars, with 99% of crash-free users and it was often featured on the App Store. On behalf of Hole19, I have attended WWDC 2016 in San Francisco.
Before working on Hole19, I worked on a few consulting agencies and had extensive freelancing experience. Over the years, I have developed several mobile and web apps both big and small.
