    Application developer

    Hungary - Last active: 1 month ago - Tests: 5

    I am a Hungarian computer engineer guy, who is programming applications since the 5th class of the primary school, so I have now more, than 10 years of computer experience - more than 5 years professional computer experience. I started using computers in Kindergarten - I was able to create directories with Norton Commander, even before I was able to write with my own hands. Personally I am a very open-minded guy, who focused his life so far learning as much as possible on every field - including soft skills, professional skills, managing ideas, marketing, communicating with people, and a lot of other things. What I can offer to you, is a very good quality of software, well tested and well documented; strong communication skills; some ideas about your project, if you wish. If these things are not important for you - because you can not afford it for example because of short time - then I am afraid, I am not your guy. If I apply for a job, and get it, my very first thing is always to make a product, which is not just acceptable, but perfect for the needs of the client, and perfect for my own requirements too. I am not the cheapest option there, but for this price, you will get a very good quality of code and you will be really satisfied with my work.
