    The most important language for any developer to be fluent in is English. I also believe that anyone can write code that computers can understand; whereas, it's hard to find people that can write code for other humans to understand. At least some time in the future will be spent on reviewing or performing maintenance tasks on the code that I write, so it is my genuine desire to ensure it is professional and readable so your time in the future is not wasted. When I work, I like to have a quick turnaround in communication to ensure the progress is constantly being made. So, if we work together, you can expect me to constantly accessible, because if I were in your position, I would want the same.

    During the last 5 years I have been working in a company that provides a full range of hosting tech support. What does this mean? - quick and complete resolution of your problem. Why quick? - because a customer wants their site to be up and running 99.9% of the time. Why complete? - because if the issue is half-fixed now it may arise in the future and the customer will have to move to another provider who can solve the problem (you know hosting is a highly-competitive marketplace). All these factors are forcing me to have (or gain as fast as possible) a wide range of knowledge in system administration, programming, code debugging and customer relationship.  less
