The main projects I took part in their development were:1. Permissions system consisting of a GUI console generating façade of PL/SQL packages integrated into various systems of HR division, Oracle based, thus providing a unified framework to control user access permissions. (VB6, Oracle PL/SQL).2. A unique tool enabling analysts with no programming skills or technical background, to create and manage sets of logic rules controlling various systems. For example, creating logic which simulates effect of different factors on contractor’s salaries. The tool had a GUI interface resembling Visual Studio IDE with tree view explorer of logic rules and a friendly text editor enabling writing down the rules in a simplified intuitive Hebrew language with semantic syntax highlighting. Users could then build the rules, observe syntax errors, maintain various versions of the rules, similar to source control systems. The rules when built were internally compiled into PL/SQL packages integrated within various systems. (Visual C++, MFC, STL, Visual C++, Oracle PL/SQL) Show less
