    PHP Web App Developer: Any Framework, APIs and UI. 15+ years (USA)

    United States - Last active: 6 days ago - Tests: 6 - Portfolio: 12

    Since 1998 I have developed dozens of web applications focusing on a wide-range of industries including custom search engines, affiliate marketing, real estate solutions and worker safety. As an autodidact, I pride myself on learning new technologies and continually improving my skill-set. As a freelancer, I believe in professionalism, clean code and representing my craft to the highest degree possible. On the server-side, Laravel is my current PHP framework of choice, although I am comfortable working with Zend, CodeIgniter, Cake and Yii. For the database layer, I have 14 years of experience with MySQL. On the client-side, I prefer jQuery, Backbone and Twitter Bootstrap. Although I am not a graphic designer, I know my way around the Adobe software suite. I write standard compliant HTML5 and CSS3. I have an eye for useable, clean and obvious functionality. I have experience with many APIs, including Amazon, Box.net, Infusionsoft, Facebook, Twitter, PayPal, eWay, Authorize.net and Google. I can write APIs from scratch and give your application a RESTful interface. I am seeking opportunities to build custom web applications from the ground up or taking an existing code base and improving upon it.

    Fullstack Web Architect

    Russia - Last active: 1 day ago - Tests: 9 - Portfolio: 10

    In four intensive years of software development, I have become experienced in a number of critical technologies, including Ruby/RoR stack, Python stack, Javascript frontend/Backend stack, and Java/Scala Web stack. My experiences and skills developed have been especially strong in tasks involving Ruby/RoR. I have found Rails among the best tools available in web development so far, so I am especially enthusiastic about RoR projects. I can also provide expertise in Scala, a great language that I admire, and somewhat in Java, which I have worked with before (I used to write Jira plugins for my corporation). In Scala stack I have worked with Play2 and Slick and have used Guice. I can also use Python if it is necessary and is related to other tasks—for example, if is the project involves Python REST API that I have to work with from JS and if I need to do some fixes in it. In JS stack, my experience is mostly with AngularJS; I also have good experience with and have completed projects in node.js/express.js. In addition to working with socked.io, I have worked with Meteor.js and ReactJS (with flux and reflux architectures). In addition, I can handle DevOP works, especially with the AWS platform, where I have built cloud application infrastructure. In a number of services (obviously ec2, s3 and SES), I used ELB and have good experience with that. Finally, I have worked with Elasticsearch (both as an admin and as a developer), logstash/kibana, redis, mongo, postgres, mysql, and oracle db. When needed, I can work with puppet/chef/(but preferably ansible) and docker, and I also have experience with Varnish cache. I prefer nginx as a web server. Obviously I use git/issue tracker and can't really live without it. I also use IDE for development (IntelliJ IDEA Ultimate) and work from an OSX environment. I also have a Windows environment for various tests. About the posted hourly rate: This is the rate that I currently ask, but the rate may be negotiated at least for first weeks/month(s) if there's a really interesting project and a team with a real potential to raise my skills. Did I leave out something you need to know? Feel free to ask any questions about anything I wrote above—and well, about anything. Oh, and one pretty important thing: I've _never_ failed a job that I took.
