    United States - Last active: 1 day ago - Tests: 5

    I have been in the telecommunications industry for over 13 years and have worked as a consultant to major Fortune 500 companies in the past for both business and technology needs. I have a vast knowledge of anything that relates to the internet, both hardware and software realms and have worked on a variety of projects ranging from the simple to large scale transition ones spanning months at a time. I understand a business' need to get projects done right the first time and have always exceeded my clients goals. If they're not happy, I'm not happy. I have a dual bachelors degree from the University of Colorado at Denver in Business Information Technologies and Business Management. My Masters in Business Administration is in International Business and most IT skills I have picked up on my own or through various courses either online or at the local community college. I look forward to working with you and completing any projects you may have, from the quick fix to an entire server farm rebuild. I am also a word class back end programmer familiar with MySQL, Bash, PHP, Perl, and Python. Please, no front end design work, I don't have an eye for creativity (unless it's something simple of course). I look forward to working with you and any projects you may have for me.

    Delphi developer

    Bulgaria - Last active: 1 day ago - Tests: 11 - Portfolio: 5

    I believe that freelancing is the best way to gather experience and improve one's skills, while giving the most flexibility to both workers and employers. I have developed in Delphi (versions 5,6,7 to XE6), C++, PHP, SQL and others. Over 4 years, I was responsible for managing computer and paper based examinations at the British Council in Bulgaria and writing software for the above. This has taught me the importance of keeping to schedules and deadlines, team-working and communication. As a Computer Science graduate, I have very good knowledge of computer systems, OS, networking concepts, information security, etc. I also have some experience with GPS, Garmin products, Google Earth/Maps and cartography.

    Python System/Web Developer

    Russia - Last active: 1 day ago - Tests: 5 - Portfolio: 3

    Python is my favourite language and I use it for implementing various system utilities and web backends (with Django framework). I am a server-side guy but despite this I also know how client-side (JavaScript, etc.) stuff works. Besides Python I like functional languages: Haskell, Ocaml, Lisp (Scheme) but they are just my hobby.

He kept me updated with his progress the entire time and responded quickly any time I needed him. His expertise in MATLAB and Partial Differential Equations was very impressive. I enjoyed working with Muhammad and have complete confidence in him when he says he can complete a project. He was the perfect freelancer for me.
