    Delphi developer

    Bulgaria - Last active: 18 hours 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.
