    Ruby, JavaScript, PHP, Java - Web Developer

    Romania - Last active: 2 months ago - Tests: 8 - Portfolio: 8

    I'm an experienced programmer, with 10+ years of professional activity. Ruby and JavaScript are the main programming languages I've been dedicating myself to for the recent years and I'm confident that I've come to have a deep understanding of the concepts, tools and libraries that are built around them. I can implement complex algorithms, I have experience in building web applications and websites (coding both backend and frontend) and I am also able to handle planning and prioritizing features to get efficient results. I'm experienced with testing applications and assuring good quality of delivered code as well as assuring a consistent and reliable code base through software design patterns and best practices. Besides Ruby and JavaScript, during my whole working experience, I've created a wide range of websites, web and desktop applications using many, different, technologies, based on multiple languages and frameworks: - Ruby on Rails - JQuery - AngularJS - Node.js - PHP - MySQL - PostgreSQL - Joomla - CakePhp - Java - GWT just to name few important ones I've been productive with so far. I enjoy learning new technologies and programming languages, trying to apply the most efficient solution to a problem and I'm also passionate about getting a glimpse of different fields related to computer science, like natural language processing, machine learning and social network graph theory. My objective is to develop long-term collaboration with people and, most important, create valuable work on projects I'm part of. I'm confident that I can bring a good percent of hard work, dedication and quality development to any business.
