Software - Judson, TX, US
I have developed applications with Xojo (a cross-platform IDE with Visual Basic like syntax with C# based Class/Object structure), FileMaker Pro and Delphi in Object Pascal. Xojo is my preferred environment but I work very well with FileMaker. I have extensive experience on both the macOS and Windows platforms. In fact, Xojo can deploy to both macOS and Windows from a single code base.I have managed large projects with multiple developers for Mainframe systems and have been a "one-man" project team doing everything from Requirements Gathering, Database Design, Application Design, Coding and Testing. I managed a company section of up to seven Programmer/Analysts and support staff with a budget of over a million dollars ( 1990 dollars).I have worked extensively with IBM Mainframe systems running OS, DOS/VSE and VM(Virtual Machine), CICS, SQLDS ( the VSE version of DB/2). I wrote and maintained programs in COBOL, PL/1, Fortran, RPG and ALC (System/360 Assembly Language). File systems included ISAM, VSAM and SQLDS. I was also the Database Administrator for the SQLDS system. I managed the Systems Development staff a defense contractor and had a government secret security clearance.I managed the required programming changes and JCL rewrites for a migration from an IBM System/360 running DOS to an IBM 4361 system with DOS/VSE and VM. This system later became a tandem processor system with two 4361s.I have experience with the now defunct Datapoint Computer systems which were the first real microcomputer system that was appropriate for business applications. Datapoint proceeded the release if IBM PCs.
