    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.

    Web Developer - Proficient in PHP, Laravel, Javascript, Ruby on Rails

    Portugal - Last active: 1 month ago - Tests: 4 - Portfolio: 3

    I've worked closely with world-class companies throughout the development of outstanding platforms that have been used by thousands. I'm proficient with PHP and I'm also a Laravel early-adopter - I've been using it since early version 3. I've developed countless applications with Laravel, attended the Laracon conference in Amsterdam and I've written several tutorials that have helped hundreds of other developers. In addition to PHP, I've also used Ruby on Rails extensively to develop complex web applications with full featured test suites. Being a Software Engineering student, you'll be sure to get solutions that are well designed, easy to scale and develop upon. I've taken a CAE (Certificate in Advanced English) by the University of Cambridge and passed with flying colours. Communicating with me won't definitely be an issue. Looking forward to working with you on your next web app!

    United States - Last active: 1 day ago - Tests: 4

    Automation/Scripting/DevOps/Data Analysis I have extensive experience with building and deploying CI/build systems, test frameworks and deployment/backup systems. I love writing utility scripts and DevOps code. I also write screen scrapers, crawlers and data parsing/analysis tools. I offer all types of testing services: usability, load, API, UI Automation, etc. I can also implement new features for your web application or fix bugs in it. Some of the tools of my trade: Python, Ruby, Javascript, Jenkins, Rails, Sinatra, Flask, bash, Java, Jenkins, Watir, Selenium and more. I'm more than willing to learn on the job too. Furthermore, if I build a tool for you, I will document it and work with you so that you can maintain it going forward, if that is your goal. I offer technical consulting as well, consider me a sounding board for any decisions related to development, testing, deployment and design.
