John Ruffin

Oracle Certified Java Programmer

In almost 2 decades of application development, systems architecture, and IT management: I have designed, coded, tested, and implemented systems in language stacks from cobol db2 cics, java jsf jms spring hibernate, to javascript node react. I've even coded in Assembler. Add Apple WebObjects ObjectiveC, Swift and React Native for iPhone and Apple Watch apps. I've seen a lot and I've done a lot.
