Lehman Brothers, Jersey City, NJ Jul 1997 to Jul 2000
Sr. Programmer/Analyst/Project Leader
●Performed mapping of 4 major Ordered Transport System (OTS) applications to usage paradigms. The deliverable was to produce for each application group high-level architectural diagram, and a description of OTS usage in major segments. Examples of a segment: NT client, Solaris client, Solaris Server, MVS Server. Usage paradigms should be a detailed description of interactions between OTS segments and other subsystems, including databases. Wrote recommendations of a migration path from OTS to a TIBCO’s Rendezvous (RV).
●Wrote a pilot system to evaluate TIBCO TIB/Rendezvous to perform throughput analysis. Perform analysis on data publish/subscribe and guaranteed of TIB/ Rendezvous CM product
●Wrote a JAVA gateway to interface with the OTC System. Wrote C++ API’s that interfaced with JNI and JAVA.

●Wrote a pilot system to evaluate OrbixTalk and Orbix 2000 Beta. Set up a server and two clients. Wrote API code to send and receive messages using OrbixTalk. Performed throughput analysis on Orbix2000 beta to provide throughput benchmarks specifying hardware, message size and other relevant assumptions for both information providers & consumers (1-none, 1-many, many-1, many-many).
Ordered Transport System (OTS)
●The OTS system is middleware system that allows for transportation of data firm wide. OTS was built on UDP platform using memory map files and written in C++ under Unix Sun OS and ported to Solaris and Windows NT. Made program enhancements to the OTS daemon. Wrote programs in C++ that performed monitoring of the TCP/IP daemon. Redesigned, wrote and implemented a Channel Server Switch enhancement to OTS. Channel Server switching provides applications a way to guarantee sequential message delivery in a Disaster Recovery Scenario, through the use of an alternate Channel Server host. When the primary Channel Server fails over, an alternate Channel Server application will be started on the alternate Channel Server host and publication will be resumed. Once an alternate Channel Server takes control, the OTS daemon logic will automatically switch upstream messages to the alternate Channel Server host, while allowing for reception of downstream messages from any of the potential Channel Server hosts. Designed and wrote a bridge (connector) from OTS to VITRIA Technologies, Inc Business ware 2.0. This connector was designed and written in C++ both on Windows NT and Sun Solaris. The bridge converted OTS messages in binary streams format and stored the messages on a VIRITA business ware server. Wrote shell scripts to facilitate this endeavor.
