Accomplishments

• Developed and maintained datamarts for several clients for email marketing using manual and automated procedures to exchange data with clients and develop profiles of client's customer from stated interests as well as derived interests based on purchase and response histories. Developed using SQL, K Shell, Unix command line utilities, pl/sql, python, perl, and Oracle. Developed web pages to record customer's interests using Java, J2EE, jsp, Javascript, Spring, (an alternative to Struts) and Hibernate (which maps database objects to java objects).
• Ordered, installed, and configured 300 gigabyte Datamart with inputs from over ten different mainframe and mini (AS/400, Sun, AIX) systems using TCP/IP FTP, CORBA and SNA local 3270 gateway for printing function and 'screen scraping', initially over leased SDLC but later revised to SNA routed over TCP/IP. Designed and developed pre-processing routines in REXX and Perl to translate inputs into database readable records. Wrote SQL to correlate different tables and correct/add to records as necessary. Also computed results such as originating repeater records (and rates). Automated these processes (transfers, pre-processing, load, updates, and correlations) using REXX, Perl and Java.
• Installed and maintained Apache web server to post reports on web. Pre-processed reports were generated using SQL, REXX, and Perl. Reports updated according to user preferences using C++ CGI to generate HTML web pages with JavaScript. Direct 'drill down' reports were generated as requested using REXX and Java CGI.
• Ordered, installed, and configured 300 gigabyte Datamart / Data Warehouse in Oracle and then DB2 with inputs from over ten different mainframe and mini (AS/400, Sun, AIX) systems using TCP/IP FTP, CORBA, and SNA local 3270 gateway for printing function and 'screen scraping', initially over leased SDLC but later revised to SNA routed over TCP/IP. Designed and developed pre-processing routines in REXX and Perl to translate inputs into database readable records. Wrote PL/SQL and SQL to correlate different tables and correct/add to records as necessary. Also computed results such as originating repeater records (and rates). Automated these processes (transfers, pre-processing, load, updates, and correlations) using REXX, Perl, and Java.
• Conducted statistical and time series analysis of the causes of troubles in C++ and SQL reported by customers utilizing Oracle, DB2, S-Plus, Rexx, and C++. Data retrieved from IMS and DB2 on AS/400 and 3090 systems.
• Designed and wrote CORBA message based object oriented (OO) knowledge base in C++ to make diagnostic dispatch recommendations based on the results of automated line tests.
• Designed and implemented OS/2 PM system in Object Oriented (OO) C++ to schedule collections of public pay phones based on weather and seasonal histories with GUI interface. Utilized Communications Manager/Server, HLLAPI, TCP/IP, and FTP for interfacing to legacy systems. Data stored and analyzed in Oracle database using SQL and PL/SQL.
• Designed and developed NYC Transit Authority money counting application using OS/2 2.0 PM, DB2 (for data storage and retrieval), Query Manager (for report generation), and Communication Manager (for APPC connection to 3090 CICS application).
• Designed and implemented user interface (PM and C) for remote installation procedure for OS/2 based distributed application (EOCF/2) utilizing Database Manager to determine the required configurations and Communications Manager for remotely executed configuration routines.
• Developed REXX API for real time message processing system using OS/2 DLL's, IPC.
• Designed, implemented, and ran PC Magazine's multi-tasking operating system benchmark (Windows, PM and C). Wrote reviews for October 16, 1990 publication.
• Developed and implemented plan to convert finance industry CASE tool from MS Windows to OS/2 PM via 'C' language macros allowing one source code and dual run-time environments.
• As a member of the original OS/2 task force and, later, consultant to the design and development teams, identified critical problems in the development of OS/2.
• At IBM Research, identified three critical problem areas where IBM Development was not actively pursuing solutions. These were a file system designed for large media devices, a multi-tasking operating system for the 80286 processor, and easy access to mainframe services. Initiated and managed the three efforts to resolve these deficiencies. These efforts resulted in HILDA, CP/286, and PDQ.
• The HILDA file system was a state of the art file system which utilizes large disk algorithms, such as KSAM for directory management. It was the basis for the HPFS released in OS/2 1.2 and a predecessor to the NTFS in Windows XP.
• CP/286 was a modular, large real memory, protected, real-time, multi-tasking operating system for the 80286. CP/286 was used as the basis for the design of OS/2 2.0 kernel.
• PDQ extended the original VSI/CPSI concept implemented in the XT-370 to provide PC applications with transparent access to host (370) file, printer, and communication services. PDQ was the basis for ECF, the IBM product which provided these services.
• Interfaced with different groups in IBM seeking to use the PC as a cost effective I/O device and led the effort to develop a real-time multi-tasking system, CP/88. Developed the working relationships so that over thirty groups could rely on CP/88 in developing their systems.
• Provided guidance and advice to the 3270PC design team to add resource tracking and recovery to the basic kernel services of CP/88. During system integration, assisted the development team in meeting their performance objectives.
• Wrote I/O drivers and interrupt handlers in PL/1 and assembly to collect and output signals through D/A and A/D converters in multitasking minicomputer operating system (Primos)
• Modelled fusing radar system (electronics) in Fortran through different trajectories to determine effects of proposed changes.
• Programmed RS232 communications processors in assembly (Z80 CPUs and UARTS on S100 bus) attached to fiber optic network throughout facility.
• Wrote tutorial program in Lisp to teach logic and probability in a game setting (Wumpus).
