I am currently developing iOS software, mainly using Swift. With a total of about 20 apps on the appStore, the main ones being related to language learning. For some examples see: http://www.sofisfun.net/Language/ and http://www.sofisfun.net/Calculators/ I recently got to work on Heroku to port some projects from the Parse.com site to open source Parse-Server, that got me on the way to get my hands on Node.JS where I built this little prime number site to get familiar with the environment. And I more recently got interested in Clojure, where I built this as a trial project.
