So far, people have visited The Homeless Mathematician, since August 5, 1995.
An undergraduate degree in pure mathematics and graduate study in biophysics provides a firm grounding in the disciplines required for detailed systems analysis and the ability to take in the meaning, nature, and importance of new technologies.
American Real Estate Exchange ( AMREX )
Bethesda, MD ( 1994 - 1995 )
Off-site development of the executive news module for the AMREX information service system, using Windows, DOS, Visual Basic and MS Access, to download articles from various news services and lexically classify them into dynamically defined subjects of interest, for subsequent retrieval within the context of a client-server data base. Performed under contract from the The Apex Group, Inc.
General Electric Information Systems ( GEIS )
Rockville, MD ( 1994 - 1994 )
On-site support for general electric information systems product release effort, for the GEIS BT2000 information services software product using Windows, c, and c++. Responsibility included the review, confirmation, analysis and correction of QDRs ( Quality Defect Reports ) that were reported from the GEIS alpha and beta site customers. During the six month tenure at GEIS, the list of QDRs was reduced from an initial 150+ QDRs to a residual level of less than 10 QDRs . It should be noted that QDRs continued to be reported during the process. Performed under contract from the The Apex Group, Inc.
National Board Of Medical Examiners ( NBME )
Philadelphia, PA ( 1993 - 1994 )
Off-site development of a custom windows DLL to control the functionality of WordPerfect within the context of an Oracle database system. The DLL allows the behavior of WordPerfect to be controlled from an Oracle data base program, to restrict editing and other data manipulation functions on text items loaded from the Oracle data base. The contents of the database are used to construct the NBME certification examination. Performed under contract from the The Apex Group, Inc.
The Apex Group, Inc.
Columbia, MD ( 1990 - 1994 )
Invited to join the Apex Group, from the previous Applied Management Sciences subcontract association, to spearhead development of a Windows software services division. Initial effort involved adapting the Windows version of the Cognos Corporation's PowerHouse software for database statistical analysis, to conform to the object management conventions of the Hewlett-Packard NewWave Desktop environment. This work was successfully completed under a joint contract between Cognos and Hewlett-Packard, with Apex acting as the prime contractor.
Developed a user-friendly Windows program for populating a sample database with non-trivial, market specific information for demonstrating PowerHouse techniques as part of the HP NewWave "demo factory".
Developed a voice recognition interface utility for the NewWave Agent, using a speech recognition board from Texas Instruments. The desktop utility consisted of two components: a Microphone icon to indicate voice recognition mode and a Balloon of recognized sayings.
After successful completion of these projects, HP invited Apex to submit a proposal for a general purpose Work Task Routing System for a network of workstations connected by an OpenMail or an HP Mail network. Submitted a proposal which significantly enlarged the scope of the original request to incorporate general script execution by the NewWave Agent. HP accepted the expanded proposal and ultimately extended NewWave functionality to accommodate specific functional requirements of the WorkRouter software. Several successful releases of the HP WorkRouter product were completed, with virtually no defects being reported.
As a follow-up project, a task tracking utility was prototyped and demonstrated to HP, who then authorized development of a production quality version for both UNIX and V3000 type data bases. The tracking utility provided a Windows based query tool to access a data base that was updated by Workrouter status massages, and allowed a network task manager to track the progress of any task on the network in a both a visual and statistical mode.
Other projects completed for the Apex Group include:
Applied Management Sciences

Charlotte, NC ( 1981 - 1982 )
As an independent consultant contracting through the DASD corporation to the Rexham Corporation, provided HP-3000 technical briefing and conversion services from an Univac 1108 to an HP-3000 environment. Reported to the director of the Rexham data center. Converted custom KSAM file access intrinsic to the HP-3000 environment of SPL-3000 and COBOL-3000, to provided standardized access functions for the Rexham data files. The porting of these custom KSAM intrinsic procedures allowed immediate porting of the Rexham corporate reporting and maintenance COBOL-3000 software.
