Spelled Paycheck Amounts
Designed and wrote a payroll software package to process various payroll system types,
including productivity bonuses, salary, hourly, multiple state taxes, etc.
The package included the feature of printing the spelled check amounts on the paychecks.
Stacked-sequence file system
Designed and wrote a tape operating system with several sort sequences of master files.
This made it unnecessary to sort master files into sequences needed by various reports.
Only transaction files need be sorted. Job run-time is greatly reduced.
Tape handling by operators is greatly reduced.
The entire set of file maintenance and report production is performed with one pass of the master file.
Authored packages at SourceForge:
An open-source mail filter program with web-based tuning tool to deliver only wanted mail by using block/buddy lists and naive Bayesian statistical analysis.
An open-source simple tiny chat-like system that provides live customer support directly from your website, so you can give one-on-one help in real-time, adding the human touch to your website. WeQuest is written in the PHP programming language and uses AJAX. WeQuest uses plain flat files with no need for database services like MySQL, etc.
Although I'm not seeking full-time employment, I'll consider a position in education, management or consulting for an enterprise interested in implementing open-source solutions on the Internet. To assure genuine interest I require compensation to attend an interview and would accept a position based on contract, not employment. Furthermore, I'd be willing to appear no more frequently than several hours per week.

Managed and executed the 3375 to 3380 DASD migration of production files with security implementation. Converted CICS to run in MVS/XA. Designed, programmed and implemented hypertext online help system to all online documentation. Implemented the RUCUS Fortran software. Wrote hundreds of Roscoe programs including structured Roscoe facility and production pickup system. Installed several system software packages. Wrote the SEPTA data security policy. Supervised and trained analysts in the maintenance of systems software including MVS, TSO, ISPF, CICS, ACCOLADE, IMAGINE, DCI, COBOL, FORTRAN, RPF, RACF, etc.
Some Quotes From SEPTA Performance Appraisal: "... has again turned in an excellent performance. ... continued to demonstrate creativity and technical competence, and has devoted much effort to instill these ideals in those around him. ... automated many of the daily functions so ... reduced staff could continue to provide excellent user and programmer support. ... revised IBM resource access processing ... providing more complete protection at a lower manpower requirement ... . ... customization of IBM's CICS ... with only limited off-shift test time, yet the results were accurate and timely."
