    Full-Stack Developer

    United States - Last active: 14 days ago - Tests: 1

    I’m a Pennsylvania-based full-stack web developer, so I can implement and integrate your frontend and your backend. Between my degree in Computer Science and Business, employment history, and side projects, I have about 3 years of experience in the areas of: • JavaScript with the jQuery and Backbone frameworks • PHP both stand-alone and with the CodeIgniter and Symfony2 frameworks • Java for both desktop applications and website backends using Tomcat • Databases including ElasticSearch (a NoSQL data store), MySQL, and Oracle • HTML and CSS • Social integration (Facebook Connect, etc.) To learn more about me, you can check out some open-source code that I’ve written on GitHub (https://github.com/danfinnie/) or view the specifics of past work experiences on my resume (http://danfinnie.com/resume) I’m a straight-shooter, no-nonsense type, so get in touch and we’ll see if I’m the right person for you. If I am, great! If I’m not, I’ll let you know and give you some tips on what to search for to find the right guy or gal.

    Josh M.

    Senior Software Engineer & Architect Specializing in .NET Technologies

    United States - Last active: 2 days ago - Tests: 6 - Portfolio: 4

    For 15+ years I have been developing software from all angles - back-end through front-end. I have worked with numerous languages, frameworks and tools but find myself happiest when working with the .NET Framework/C# - I have worked with the .NET Framework since it was first released. Over the past decade-and-a-half, I have proven myself a valuable asset to any team/project on which I have been placed. I have very strong development skills including .NET (C#), database design, UI/UX, front-end (HTML5, CSS3, JS), back-end (SQL Server, MySQL), web services/APIs, etc. I always end up being the go-to guy for other team members when they have questions and I'm happy to mentor more junior developers. I've worked on projects of all sizes ranging from small internal systems to large public-facing systems. I am constantly keeping up with the latest trends in software development and in my free time I usually have one or two personal projects going on. I tend to prefer working with C# but have also worked with Java/J2EE, Ruby on Rails, PHP, etc. I am open to other languages, technologies and frameworks - whichever is best for the job. I have strong front-end web development experience including working with 3rd party frameworks such as jQuery, jQuery UI, Knockout, Bootstrap and others. I have designed and built web applications from scratch and have also worked with designers to implement functionality based on pre-determined designs. I'm a hard working software engineer who prides himself on the quality and completeness of his work. I work efficiently while adhering to best practices and remaining mindful of performance, potential bottlenecks, memory usage, etc. I would be a great addition to any project as a single developer or as a new developer on an existing team.

    Lewis Sellers

    Senior Developer

    United States - Last active: 30 days ago - Tests: 1 - Portfolio: 2

    I have a degree in Computer Science and have been working as a contract web developer for quite a few years now. I've worked in many languages and technologies over those years and, given the proper frame of mind and incentive, I'm perfectly fine with learning something completely new to get a project done. Recently I've been moving into iPhone and Android Development but have also spent a lot of time working with PHP, MySQL + Postgresql, Laravel, Ajax (Json), JQuery, MCV + Activerecord patterns, MongoDB/Map-reduce, Facebook/Twitter/Google social APIs and Twillo SMS APIs. Real estate is almost a specialty of mine: Specifically data-mining (including scraping) real estate information and working with IDX and RETS property feeds. In the past I've also spent a lot of time working in ColdFusion and with C++ COM objects. Basically a jack-of-all-trades full-stack developer.

    Software-Developer (PHP, MySQL, Javascript, AJAX, Symfony, jQuery)

    Germany - Last active: 2 days ago - Tests: 4 - Portfolio: 18

    Since 2006 I implement PHP/MySQL Database Applications - starting with the simple CMS-Website over Online Shops with backend interface to existing software, ending with high-demanding customized business applications - with established languages and techniques like XML, HTML, CSS, AJAX and Javascript and several CMS- and E-Commerce systems as well as Frameworks. In the last years Pimcore, AngularJS, Symfony2 and Knockout were my regular tools of occupation, but I'm able to quickly read myself into other systems. Also I was able to extend my knowledge about Mobile Development with Objective-C for iPhone/iPad/iPod-Apps, as well as Java for Android. In addition to that I realized several Database Publishing projects – automatized catalog production - with direct, standardized PDF- Creation or with Indesign-Plugins e.g. Werk II's priint:comet oder DATAFORM.
