About

I have a passion for designing and writing great software. Since starting at twelve on an Apple //e with simple BASIC games and progressing to a complete 6502 assembly text-based-GUI syllabus builder, I've learned several languages and worked on a wide array of applications and architectures.

For over twenty years I've focused on web-based Java and PHP systems backed by MySQL and Oracle databases and dabbled in React.
