I began in IT working on IBM S/370 systems programming in Assembler 370, COBOL/370|COBOL II, CICS Command Level & Macro Level, SAS, JCL, and ISPF scripting. I worked with VSAM file systems and both TCAM and VTAM communications. I then installed and managed VSE/ESA with CICS/VSE and VTAM/VSE on IBM 4381's and 9221's before migrating those environments to RS/6000's running AIX.

Since then, I have worked in both Oracle Enterprise Linux and Windows Server, running Oracle, MySQL, and SQL Server databases; programmed in C, C#, PHP, JavaScript, and WinBatch (a scripting language); and architected GJXDM and NIEM XSDs.
