James (Jim) T. Henry III

Systems Developer, CoreCard Software, Norcross, Georgia
(earlier was called Delos Payment Systems; a spin-off of Paysys International)

• With one other developer, built simulator of Visa/MasterCard networks for testing a commercial credit card application. I was chiefly responsible for the network code and the configuration file parser. We built the simulator using Visual C++ 6.0, MS SQL Server 7.0, and Delos' house language (to re-use code for generating and parsing Visa/MasterCard messages). It has been used extensively for regression and stability testing of CoreCard's chief product.
• New features and defect fixes for the interpreter of CoreCard's house language, including:
  • automatic configurable restart, with or without machine reboot
  • rewrite of configuration file parser for the language's network protocol to make it easier to add new configuration variables
  • improvements to the efficiency of the network protocol
• Occasional build shepherd (managing official build process: announcing code freeze, being first to investigate defects discovered by the testing team and assigning them to appropriate developers, deciding what check-ins to allow during freeze, and deciding when to lift the freeze or branch the source control database)

Systems Developer, PaySys International, Norcross, Georgia

• Developing new features for the interpreter of PaySys' house language (written with MS Visual C++ 6.0, with Unix portability in mind), including:
  • new expression functions for time and string manipulation
  • enhancements to network protocol so a job done acknowledgement message could carry a payload with information about its context
• Developing financial systems software using PaySys' house language
• Defect fixes in the above-mentioned systems
• Writing Perl scripts for testing PaySys' web applications
• Writing bash/awk scripts to analyze multi-megabyte trace files from a financial transaction processing system
• Writing and editing feature requirements documents, configuration file format documents, sections of the reference manual for PaySys' house language, and the like
• Support of testing team
• Occasional build shepherd

Software tester, PaySys International

• Performed regression tests
• Developed new test plans
• Automated regression and performance tests using WinRunner, LoadRunner and shell scripts
• Improved daily/official build process with automation shell scripts and clearer procedure documents
• Redesigned (with two others) schema for regression test database
