★★★★★ I'm programming since I was 15. (12 years of programming experience in general) I have wide set of skills needed for developing for Mobile, Web, Desktop and even embedded devices. Now I'm mainly iOS & Android developer with 7 years of experience in this area. Windows Phone developer for 2 years. I develop apps as freelancer, but I'm also iOS & Android indie developer that made successful apps with more than 3 millions downloads, so when I complete your app I can help you with publishing it on the App / Play Store and give you advices about ASO / promotion. Please check out my website in portfolio. I'm also experienced in PHP, SQL, Javascript, C++ and more. I can learn any new technology easily. You can check out example of one of my retro games written in my custom cross-platform engine that makes use of Lua/Java/Obj-C/C++ by looking for "Wildagotchi" game on Google Play, App Store or Windows App Store.
