    When you hire me, you're hiring a top 5% Upworker with multiple successful projects and universally happy clients. I am an expert Ruby and Rails developer with more than 6 years of successful projects with Ruby on Rails versions 2.3 through 4.x. I enjoy working on everything from ecommerce to line of business applications and I specialize in identifying and fixing security issues. I can occasionally be found on the #rubyonrails freenode IRC channel and my github can be found under the username latortuga. I have contributions to major open source projects including Ruby on Rails, Devise, ActiveAdmin, cache_digests, warden, spree, and zeus. I am generally interested in Ruby or Rails development proposals, provided they include information about the actual project and not merely a list of skills.

    PHP Web Development

    Bahrain - Tests: 2

    Programming is my life and my language. My brother knew I was a programmer before I did. He bought me that first book when I was about 10. That was 23 years ago. I am a programmer with experience in many languages, platforms, and operating systems. I love working with small companies and startups. Whether you need someone to lead your team, program into the wee hours of the night, or just need someone to talk to, I can help. I have always enjoyed the challenge of creating interactive software. With the birth of the modern Internet, I found a new love in web development and web programming. I face every new piece of code as a fresh new beginning... a chance to do it even better, while, still using "what works" from the past. My objective, here at oDesk, it to provide potential employers with my expertise in the field of website design, development, and programming. #1 and All PHP, MYSQL, POSTGRE SQL, JavaME, Javascript, C++, Java J2EE, J2SE.

  4. Steven J. Agency Contractor

    Experienced, versatile developer and analyst

    United States - Tests: 10

    I have an extensive background in developing web systems with a variety of languages. I work with a team at TriTrySystems so that we can help clients have a team of developers, not just a single person, which gives a reliable source of expertise to our clients and provides for additional developer resources if necessary. We are also available to do project "rescues" and/or QA, for when previous developers have not been able to finish projects, whether they be in PHP, Perl, Python, or Rails. I particularly enjoy projects involving complex machine learning, systems programming (e.g., kernels, device drivers, filesystems, etc) or functional programming (e.g., OCaml, Haskell, Scala, Erlang, Clojure, etc).
