    Application Developer mainly in tune with Web technologies in a variety of scripting and programming languages. New and quick challenges or build new and improve constantly are two of my main interests. More inclined to be a "Jack-of-all-trades" do all in a wide range of skills than a fixed specialist in a single narrow technology. Tenacious, hard-working and troubleshooting expert. Although i possess a wide range of skills available for you, I will always be honest and quick so you don't waste time back and forth with me - you will know straight away if I am able to do the job or not.
