  2. Maksymilian A.

    HTML5, CSS3, JavaScript, jQuery, Ruby, Sinatra developer.

    Poland - Tests: 3

    I believe that the Internet evolves at the rapid pace, technologies and methods of web development are different each month but only little group of certain web makers understand that fact and this effects in division of them into two groups: those who stick with writing code in old and deprecated way and those who use fresh yet production ready technologies and don't fear to play with experimental ones whilst maintaining high quality of the code. I proudly announce that I belong to the latter group, because I love innovation and self-improvement. In real life, high quality products and services are what I prefer thus offering the poor quality work would make me feel extremely bad. I've spent several years watching the Internet from the other side on my personal websites, now I decided to freelance to improve the Internet. As a beginner at oDesk, I decided to charge little less than usual ( Hourly rate below is a median one, the exact rate will be given during the consultations about the product ). Please do not hesitate to contact me about anything, I am certain that we will make some great business together.
