    Experienced Web Developer (Ruby on Rails/SaaS)

    United Kingdom - Last active: 9 days ago - Tests: 6 - Portfolio: 11

    My website is available at http://www.rehanjaffer.com/ for some idea of what I do in my spare time, programming-wise. As a child I aspired to be an inventor. Lego blocks, circuits, anything I could get my hands on, I'd experiment with and learn what I could do with it. I dreamed of a day when I would be able to build a robot myself. Programming was been the first practical realisation of that aspiration, as it allowed innovation and creation, the ability to dream or envision a website or application and turn it into reality. With the right set of tools, an idea can be brought to life. As a result of what some might call 'obsessive traits' my knowledge is quite diverse and in many cases the interests merge. My own deeper studying of psychology aids in eCommerce development and design by understanding the need, where possible, for empirical testing, along with being able to apply standard human behaviour (i.e less clicks to purchase leading to a greater chance of buying). It has also lead me to understand my own blind-spots and where to compensate for them in programming. An example of this would be the confirmation bias experiment where participants were asked to identify the next number in a sequence and work out the rule. The sequence they were given was 2, 4, 6. Most correctly guessed the next number would be 8, but incorrectly guessed that the rule was "adding 2 to each new number", when in fact it was simply "any set of ascending numbers". The failure to test alternative hypotheses was confirmed in other similar experiments, and there are practical applications of this in unit testing. A simple example being testing the cases that should work, and not testing cases that shouldn't, something far too common. In development, this has resulted in me specialising in a few key areas (specifically Rails and Ruby) while also understanding the full stack from servers down to interpreter internals. I'm able to write code in most major languages, but to truly know a language requires learning the idioms, experiences with common issues and bottlenecks, and knowing the best practices.

    Web Developer

    Germany - Last active: 1 day ago - Tests: 4 - Portfolio: 1

    Hey there! I'm a freelance web developer based in Germany. Over the last several years I've been building websites using PHP, Ruby, Rails, jQuery, Javascript, Bootstrap, CSS3, HTML5 and more. I have experience in working with such PHP frameworks as CodeIgniter and Laravel. I also enjoy scripting and automating tasks with the help of Ruby or Python. So I would be more than glad to help you scrape a few thousand web pages in order to get the data you're looking for. I'm currently a student at a German university, so I have to deal with both German and English on a day-to-day basis. Moreover I'm a native Russian speaker. So feel free to contact me in case you are looking for a really human translation of anything involving any of these three languages.

    Experience and Skill: I do writing and marketing.

    United States - Last active: 04/15/2013 - Tests: 5 - Portfolio: 6

    I've carved a niche for myself in writing for clients that need someone who can not only write well for your company but also not be a pain to deal with. That is a winning combination, I've found. Rather than a text-producing robot churning out bland work, I offer you a person on the other end of the line who can disagree respectfully if he thinks things are going in the wrong direction and offer alternative solutions. I'll do my best to make sure that the money you've payed to me will make you more money.

    Senior Developer

    Slovenia - Last active: 03/24/2014 - Tests: 2 - Portfolio: 4

    So yeah, a little about me. I'm 26yo from Slovenia. I just finished my study (masters) with the official title Organization And Management Of Information Systems. I was creating webpages since I was like 12 years old (Notepad, FrontPage, Dreamweaver and what not), then I got into hacking with PHP and working first at SmartCom building internal applications for about a year and a half and then with the biggest Slovenian web agency Innovatif for about 2 years. Next I got into freelancing where I did a Mac app with Objective-C and many Ruby/Rails web apps. For the last 2 years I'm almost exclusively a Ruby developer. I'm also the organizer of Slovenia Ruby User Group. If you want to know more, please don't hesitate to contact me.
