    Full-Stack Developer

    United States - Last active: 4 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.

    Perl programmer and systems administrator

    Andorra - Last active: 1 day ago - Tests: 2

    I've been either writing perl or administering systems (or both) for the past 30 years. I've used perl both for administration and large web projects. During that time I've worked for many of London's banks and telecoms companies. I was head of server support for Credit Suisse, undertook desktop refresh project for Merrill Lynch and server architect for Sportal, CTO of FDD, and have held a wide range of senior admin or development roles. I've also been involved with many startups (3 of them my own). I'm creative, understand business imperatives and finances, and have undertaken technical marketing and sales. Recently I've written flooting.com a site devoted to reuse in OO Perl. It's live now, feel free to take a look. I now live in Andorra with my wife and children. I'm quite keen to keep my skills current. If you need someone to quickly grasp what you need and hit the ground running, I may be the right guy for you.
