The Project involved developing a JAVA and .NET-based application for the meat processing industry for USDA HACCP (Hazard Analysis and Critical Control Point) compliance. David was the architect and designer for the project, which hit deliverable #1 within3 months. The system had 3 important components: 1) collecting data from PocketPC handhelds at the shop floor level (temperatures from handhelds with attached probes) and 2)queuing the transaction via SOAP to the JAVA-based server over the corporate 802.11 wireless intranet. A 3) Java-based rules engine in the server evaluates incoming data, updates the database and compares that data with compliance to XML-based rules in the database. The main feature of the system was the ability of the administrator to change business rules on the fly without changes to the code. After development of the use cases, David designed classes for a java based rules engine. David designed the entire application and oversaw administration of the Oracle 9i database and creation of the indexes, triggers and sequences to maximize performance of the database.

Project:            Web-based timesheet data collection portal                 2003

Fluor-Daniel         Irvine, CA (www.fluor.com )

The company (world’s largest project and construction company) needed a web-based time card portal for acquiring time from remote locations to SAP. Large construction sites in different cities were not integrated, and time cards would be delayed as much as 2 weeks from time of work done to time of billing. The need was for a web solution that could consolidate timekeeping and project management hours, thereby replacing multiple PC-based “sneaker-integrated” systems. The development of the system would help reduce the license costs of SAP, allowing a large number of users access to the portal. This system used an open-source application server to create a high-availability transaction engine for messaging occasional 5,000 hourly time sheets to e*Gate, which managed integration to SAP. Also established CVS as the software management repository.

Project:         SAP Web             2001-2

UniLever           (www.unilever.com )

This worldwide client wished to web-enable an ERP application for hundreds of users. The process was to develop a user interface for the entry of shop floor data, replacing functionality in the ERP solution. The data entered was then transferred from the Web application to the back end ERP system thru messaging software (MQ-Series) for the transaction, as well as for reports. Data was then updated into the ERP application for the transaction. The JSP user-interface provided for Sales Orders, Sales Order Shipment, Purchase Orders, and Journal Vouchers.  David developed the UML for the application,defined the queue manager, queues and the Channels for MQ-Series to integrate the data between the Web Server and the UNIX Server, which had the backend ERP solution. He designed the data format to be integrated to MQ-Series queue and triggering of the Queues. He also created UNIX scripts needed to start the ERP session to upload the data. Reports were also managed via the HTML front end.Report criteria entered was transferred to the ERP system via JAVA RMI methods.
