The software was written in Java and involved development of the core API, using RMI, and using Struts for development of the web interface, with some Javascript, ensuring cross- browser functionality. The front end was deployed on Sun One Web servers running on Sun Solaris systems, using an Oracle database. Additionally worked on an embedded C/C++ project, for a MEMS based, ‘street-cabinet’ solution, using eCos and SNMP.

Position: Java application developer
Development of a connectivity solution, allowing travel agents to connect directly to various hotel reservation systems, to perform reservations and inventory checks. This was implemented using a combination of Java, Weblogic and SOAP, with the system acting as a routing agent for the communications. Later on this was modified to fit the needs of Expedia, to allow them to be the sole client connecting directly to the hotel systems, using the OpenTravel Alliance specification. The system was designed to allow a fallback to fax, after all failovers (message store/forward, retries...) were exceeded. Additionally test tools were developed, to allow both in-house developers and hotel partners to test their communications for protocol correctness according to OTA specifications, proper error handling and load handling.
