Multifaceted, versatile software development engineer, computer scientist, and writer.


Greetings! I'm William Gilreath  (he/him/his)

I am a multifaceted senior software engineer, web developer, mathematician, and computer scientist.

I love working with software--developing, testing, writing, and analyzing. In my spare time, I write both code and technical articles, and narrative prose--novels, short stories, book chapters, and poetry. I am showcasing some of the algorithms, code, programming languages, research papers, and web apps I have created, written, and published.


I have an inactive blog about my technical dabblings and other things...entitled "Much Ado About Nothing" where I write about this, that, and the other, but not of late.


My current project is a new programming language "ZeptoN" from "zepto" + "N". A small programming language that is the Nth programming language (as programming languages go from 1 to N) where this is the Nth language.

This ZeptoN white paper describes the language, its goals, and gives many examples with output to illustate the ZeptoN programming language.

ZeptoN extends Java by adding a program entity construct like a class (without the object-oriented trimmings), with an implicit program entry point as a block. Yet ZeptoN is completely Java syntax and concept compatible. ZeptoN puts the program back into Java programming!

ZeptoN is now available on my GitHub repo for download, or the GitHub page. This is the ZeptoN "Echo" trans-compiler which transpiles to Java, and then uses the Java Compiler API to build a Java bytecode .class file.

I have had an article about ZeptoN published on JavaCodeGeeks describing extending the language.

ZeptoN Code Example...

   prog helloWorld {
      println("Hello, World!!!");


Here are some books I have written.

Here are some theoretical research papers I have written, and have been published by the General Science Journal.
