Project: MyCruiter
Technologies: .NET, C#, Java, J2EE, Oracle ,Java, Perl, C++
Description:
MyCruiter is a specialized search engine which extracts job data from corporate web pages, indexes it, and make it available to end users to query. The system’s middleware is implemented via J2EE components including servlets and EJBs hosted on Oracle Application Server 9i. Oracle 9i database is also used.
I have developed a new front-end client written in C# to the existing MyCruiter backend system. This was done because the native Windows APIs allow a faster and more attractive GUI than the existing Java Swing Applet user interface.
Although the front-end has been changed to use Microsoft technologies, the middleware remained unchanged using J2EE and Oracle technologies respectively. This decision was based on the proven performance and economy of server-side Java as well as the fact that .dot net Server is not yet available.
Development of Windows Forms front-end GUI using C# and Visual Studio.
Creation of compatible web services to communicate between a Windows .NET front-end client and J2EE middleware.
Management of other technical personnel
Lead role in developing Java servlets, applets and applications using Borland JBuilder 3.5.
Created robot program to search the Web for job data by recursively searching Web pages starting from a root URL. Program was implemented using Java servlets and Perl. Search parameters include maximum number of pages, tree depth, and text required on page.
Developed Oracle database to store job data collected from the Internet. Web page text is indexed by common search keywords in order to speed subsequent searches. Designed tables and indexes for optimal speed and normalization.
Developed Java applet for users to access job data stored in Oracle database. Implemented using Java Swing in order to provide a fully functional and attractive user interface including tabbed panels and tree controls. Utilizes threads so that interface remains responsive while searches and updates are in progress.
