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.

United States - Last active: 1 month ago - Tests: 5

Since graduating from the University of Washington I’ve worked in the industry as a software developer for the last seven years. I’ve worked on a large array of individual and group projects in a variety of roles. The majority of my past projects have revolved around a very large Java based SAAS application using Servlets/JSPs, Oracle SQL, HTML, CSS, etc. I’ve also spent some time developing interactive visualizations in Raphael.js for the web and OpenGL/Core Graphics for iOS apps. I’ve built several iOS apps, two in-house enterprise distribution style and three for the App Store, using Xamarin.iOS and RubyMotion. I’ve spent the last year and half or so working exclusively on a Ruby on Rails based web application. I love learning new programming languages, frameworks, and technologies.

United States - Last active: 24 days ago - Tests: 4

I've been programming professionally for more than ten years. In that time I've worked with C, Java, Pascal, C++, Common Lisp, Perl, PHP, and Python, and built web applications in both Perl and PHP on top of MySQL, Oracle, and PostgreSQL backends. I've also built servers from the ground up - my distro of choice is Ubuntu Server these days, but I've built Red Hat, Fedora, Debian, Gentoo, and even installed Linux from scratch once. Basically, if it needs doing, I can do it, and I'll do it better than anyone else you can find. If I can't, I won't take the job. He estado programando profesionalmente durante más de diez años. He trabajado con C, Java, Pascal, C + +, Common Lisp, Perl, PHP y Python, y aplicaciones web construidas tanto en Perl y PHP con MySQL, Oracle, y PostgreSQL. Yo también he construido servidores desde cero - mi distro de elección es Ubuntu Server en estos días, pero he construido Red Hat, Fedora, Debian, Gentoo, e incluso instalar Linux desde cero una vez. Básicamente, si necesita hacerlo, puedo hacerlo, y voy a hacerlo mejor que cualquier otra persona que pueda encontrar. Si no puedo, no voy a tomar el trabajo.
