    Oracle Developer

    Serbia - Last active: 4 months ago

    My love for computer programming started when I was 10 years old. It was the time when Amiga was still in diaphers, Commodore 64 was considered a great gaming machine, and IBM PC was nothing more than a really powerful calculator. Throughout the years I worked in Basic, Delphi (my favourite) and C. I also built a few websites when world wide web era started, mostly for my own pleasure. Then nine years ago I decided to try something different - I started working as Oracle Developer. Projects I was involved with include working on a core banking software, data warehouse solution for a bank, banking reporting, and recently on a betting software. I still casually program stuff in PHP and Delphi.
