I can prototype the application UI for you. WEB BACKGROUND I have wide knowledge of many modern technologies in web development stack -- from low-level networking protocols and system tweaking to server-side programming (PHP+Laravel, Node.js, MySQL, MongoDB) to client-side programming (HTML5 APIs, Javascript, Ajax, AngularJS). I could solve the programming task of any complexity for you. I prefer developing complex and unique applications and/or user interfaces rather than creating simple applications which are similar to each other.
